          Now you can use your own version of OpenAL.framework for
          selecting various audio output device.  Plus, you can build FG/SG
          on Snow Leopard with cocoa configuration.

        * simgear/scene/material/EffectCullVisitor.cxx: don't render an
          EffectGeode if there is no valid technique

          Normal geometry has a default effect; geometry with no default
          effect is unlikely to look correct with no state set applied.
          This fixes the problem of clouds being displayed as multi-colored
          rectangles when shader effects are turned off.

          SGSoundMgr::stop(): do not try to erase buffer items one at a
          time

2009-12-08 06:37  timoore

        * simgear/scene/model/: ModelRegistry.cxx, ModelRegistry.hxx: take
          locks out of ModelRegistry

          I don't want to get into testing for tr1::unordered_map, and the
          boost compatibility doesn't exist in 1.34.

          Author: Tim Moore <timoore@redhat.com>

          know, the real problem turned out to be the distance attenuation
          function..

2009-11-16 00:11  timoore

        * simgear/scene/model/model.cxx: When instantiating effects, copy
          user data of any created nodes.

          This bug was the cause of the huge memory consumption / death
          reported at some places: the BVH data on "raw" .ac models (random
          objects) was dropped on the floor.

          Author: Tim Moore <timoore@redhat.com>

2009-11-15 01:41  timoore

        * configure.ac: Bump boost version to 1.37

          scene/material/Effect.cxx, scene/material/Effect.hxx,
          scene/material/makeEffect.cxx: optimize creation and sharing of
          effects

          Implement equality test and hash for for property trees.  In an
          Effect, make a hash table of Effects that inherit from it keyed
          on their unmerged property tree. Using that, makeEffect() should
          return a single Effect for given property tree description.
          Animations may change that in the future...

          example, with the random models from the materials library.

        * simgear/props/: props.cxx, props.hxx, props_io.cxx: Property
          system optimizations

          Profiling startup with the new effects code exposed some
          performance gotchas. The objective is to reduce allocation of
          std::string temporaries, especially when looking up node path
          names. Also, I changed some paths to initialize strings with
          strings instead of char *; this causes less allocation, at least
          with glibc. Also, eliminate the old version of find_node and its
          helper functions by writing the template version of find_node_aux
          to handle an explicit index parameter.

          Also, add const char[] as an internal property type

          This doesn't actually add a new type to the property system, but
          allows using character arrays as arguments to certain templates.

        * simgear/props/: props.cxx, props.hxx: Extend properties to
          support new property types.

          An SGRawBase class has been added as a base class to the
          SGRawValue hierarchy so that SGPropertyValue functions don't
          necessarily need to know the type of the value stored in the
          node.

          A new SGRawValueContainer class stores properties that shouldn't
          be stored in the node itself. PropertyTraits indicates if a type
          is stored in the property node or externally.

          Add getValue and SetValue template member functions to
          SGPropertyNode.

          Read and write new extended properties.

          Rearrange props.hxx a bit so that the template magic actually
          works.

          Split out extended raw value virtual functions into a seperate
          base class.

          SGRawExtended is chosen as a base class of SGRawValue for
          extended property types.

          static_cast.

          Move SGPropertyNode::Type out of the class into simgear::props
          namespace. Add a PropertyTraits class so that templates can
          calculate the property type tag based on a C++ type.

          In destructor, delete _value.val if it is not 0 (and the property
          is not aliased).

          of sg, it makes the code's intent clearer and helps to find
          headers. (And it's a few milliseconds faster, too.)

        * simgear/scene/tgdb/obj.cxx: The chunked stuff is no longer needed

          ... I (Mathias Froehlich), believe that it is more performant

          expense of tight culling.  I (Mathias Froehlich) also know that
          the CPU is more performant on smaller chunks building the old
          flat groundcache on such tiles. :) So this code *was* to balance
          these two contrary requirements to some degree.

          Now we have optimized datastructures for drawing and differently
          optimized datastructures for intersection tests.

        * simgear/timing/: sg_time.cxx, sg_time.hxx:  For the first time
          (no pun intended) in almost ten years time (again no
           pun intended) that I'm touching the time library.

           Brian Schack reported that the traffic scheduler messes up the
          timestamps
           of the atlas network output. As it turns out, the c library
          functions
           asctime, and gmtime use a static copy of the tm struct to do the
          internal
           formatting. Our linux port of the SGTime class, incidentally,
          also stored
           it's master time stamp in this very same struct. Thus,
          formatting an
           arbitrary time value, would have the unwanted side effect of
          time travel.
           Usually, this would go unnoticed, because the actual time
          parameters would
           be updated before any damage could be done. But unwanted side
          effects, as
           in Brian's example could occur.

           On the MSVC port this appears to not have been a problem. Since
          that port
           used a copy of the tm struct to store it's master time stamps.
          Since the
           MSVC code also compiles cleanly on linux, it seems to be the way
          to go to
           use that approach. In addition, it also removes some conditional
          compile
           directives.

           I've only run a short test, but didn't see any undesirable side
          effects.

          Buchanan :

          Attached is yet another 3D clouds patch, to fix the following: 1)
          The 3D clouds were not modified by the cloud coverage, due to
          some problems with osg::Switch 2) METAR changes to cloud coverage
          were not obeyed.  3) Making changes via the Cloud dialog had no
          effect unless 3D clouds were toggled.  4) Cloud cover was too
          sparse.  5) 3D Stratus clouds caused performance issues on some

          Tim's improvements - Changes the transparency of the clouds.
          Previously, the clouds were transparent at 0m distance, opaque at
          200m, then gradually more transparent to the fog limits. This
          meant they were generally quite transparent. Now, they are opaque
          from 200m to 15km, then become transparent at 20km. A side effect
          of this is that the current textures could probably benefit from
          being made slightly transparent to improve the blending of the
          sprites against each other.

          This provides the following enhancements & bug fixes - Fix the
          chequer-board bug.  - Add proper cloud coverage function - so
          scattered clouds are now truly scattered.  - Add real-time
          control for visibility range.  - Use a limited set of clouds
          rather than generating a completely new Geode for each cloud.
          This saves sorting and display time.  - Add controls to Rendering
          dialog to allow fine-tuning of the number of sprites, cloud
          visibility and the number of different types of cloud.  - Add
          some variance to the sort back-off to avoid all clouds being
          sorted at the same time.  - Pack attributes into vectors for
          performance - Re-order the cloud type determination code so that
          if a cloud layer could either be stratus or cumulus, cumulus is
          used.  - Lowered the cloud level in the standard cloud
          configuration slightly so a cumulus layer is generated rather
          than stratus.

          These last two mean that you should see some 3D cumuli if
          disabling real weather fetch.

          is still a problem when viewing a layer below the 3d clouds, and
          I'm not sure if/how I'll manage to solve that. Thanks to Tim for
          pointing me at the correct code (again).  2) Performance

          Well, the cause was a bug in my code, but it didn't expose itself
          until we moved to multiple cameras. The attached patch fixes the
          problem.

          I've also put in a new heuristic to improve the frame-rate.
          Clouds that are already sorted are likely to still be sorted in
          subsequent frames. Therefore I've put in a back-off mechanism for
          the bubble-sort pass. This should mean that if you stay
          completely stationary, once the clouds become sorted they will
          eventually only perform a bubble sort pass every 128 frames.

        * simgear/scene/sky/CloudShaderGeometry.cxx: Manuel Massing:

          Attached is a small fix for the sorting in
          CloudShaderGeometry.cxx.  I think the sorting problem stems from
          the osg idiosyncracy to store transposed matrices...so the
          intuitive

                 osg::Vec4f p = vm *
          osg::Vec4f(_cloudsprites[i]->position.osg(), 1.0f);

          needs to be replaced with...

                 osg::Vec4f p =
          vm.preMult(osg::Vec4f(_cloudsprites[i]->position.osg(), 1.0f);

          The patch also optimizes the distance calculation - it evaluates
          the distances in model space instead of eye space, which reduces
          computation to a dot- product instead of a matrix multiplication.

          It fixes the following issues (to a greater or lesser extent): 1)
          Performance. Quad trees used to improve culling, and the sprites
          are placed on the surface of a sphere rather than randomly
          throughout the cloud, requiring fewer textures. This saves about
          5-10fps on my machine.  2) Disabled 3D clouds have no performance
          impact. Previously they were still in the scenegraph. Now they
          are removed.  3) Clouds are now loaded on start-up, and don't
          require the scenario to be changed, they also work with METAR.
          4) The cloud field is shifted as you travel. There's a small bug
          in that the clouds "jump" as you reach the edge of the field.  5)
          Iterative sorting of sprites. This doesn't appear to solve the
          alpha blending problem completely, but may help a bit.

          Sync with Nasal upstream (Melchior already had a chance to test
          this, so hopefully not too much breaks).  New syntax features:

          1. Call-by-name function arguments.  You can specify a hash
          literal in place of ordered function arguments, and it will
          become the local variable namespace for the called function,
          making functions with many arguments more readable.  Ex:

             view_manager.lookat(heading:180, pitch:20, roll:0, x:X0, y:Y0,
          z:Z0,
                                 time:now, fov:55);

          Declared arguments are checked and defaulted as would be
          expected: it's an error if you fail to pass a value for an
          undefaulted argument, missing default arguments get assigned, and
          any rest parameter (e.g. "func(a,b=2,rest...){}") will be
          assigned with an empty vector.

          2. Vector slicing.  Vectors (lists) can now be created from
          others using an ordered list of indexes and ranges.  For example:

             var v1 = ["a","b","c","d","e"]

             var v2 = v1[3,2];   # == ["d","c"];
             var v3 = v1[1:3];   # i.e. range from 1 to 3: ["b","c","d"];
             var v4 = v1[1:];    # no value means "to the end":
          ["b","c","d","e"]
             var i = 2;
             var v5 = v1[i];     # runtime expressions are fine: ["c"]
             var v6 = v1[-2,-1]; # negative indexes are relative to end:
          ["d","e"]

          The range values can be computed at runtime (e.g. i=1;
          v5=v1[i:]).  Negative indices work the same way the do with the
          vector functions (-1 is the last element, -2 is 2nd to last,
          etc...).

          3. Multi-assignment expressions.  You can assign more than one
          variable (or lvalue) at a time by putting them in a parenthesized
          list:

             (var a, var b) = (1, 2);
             var (a, b) = (1, 2);               # Shorthand for (var a, var
          b)
             (var a, v[0], obj.field) = (1,2,3) # Any assignable lvalue
          works

             var color = [1, 1, 0.5];
             var (r, g, b) = color;  # works with runtime vectors too

          database pager will get passed through the SharedStateManager
          anyway.

          paging patch from Till Busch

          Comments from Till: I started the project at the end of february
          with a simple idea: move all 3d-model loading to the
          DatabasePager-thread. my first attempts looked promising, though
          they were a little too optimistic (or naive?). the patch has
          evolved a lot since.

          currently it does the following things: 1. revive SGModelLib,
          move functions for xml-model-loading there

          2. replace all calls to sgLoad3dModel with calls to either
          SGModelLib::loadModel() or SGModelLib::loadPagedModel() almost
          all models will be loaded by the DatabasePager. the few
          exceptions are: your own plane, shared models in scenery, random
          objects, AIBallistic models.

          3. simplify mode-loading functions (avoid passing around fg_root)

          4. avoid supurious MatrixTransform nodes in loaded models

          5. fix some memory leaks

          Cleanup and performance tuning of the random trees code.

          The QuadTreeBuilder class was completely revamped as a templated
          class to support flexible creation of scene graph quad trees, and
          a major bug was fixed as well. Now it actually generates
          quadtrees instead of some weird striped thing.

          One StateSet is shared among all the "forests." The trees are
          drawn after normal terrain objects to minimize some of the
          transparency related artifacts.

          Lighting was implemented in the ShaderGeometry shader (for both
          polygon sides). Ambient-diffuse values for trees are hard-coded
          in TreeBin.cxx.

          DotOsg wrappers were added for ShaderGeometry so it can be output
          in the scene graph dump.

          etc.) and we used shorts to index into larger structures.  But
          this capped many of our structure sizes to a maximum of 32768.

          By switching to unsigned shorts in the future, we can double the
          maximum object/index counts without losing anything.  This was a
          pretty major oversight in our original specification.

          I have bumped up the native object file version from 6 to 7 and
          added code in the reader to maintain full backwards compatibilty

          The cause seems to be the condition in SGMaterialAnimation.cxx
          l.277 ignoring any texture update by the UpdateCallback (only
          there <texture-prop> is looked at)  without an already existing
          stateSet.  That in turn will not be created with a <texture-prop>
          alone l. 379ff.

          Unless I overlooked some compelling reason contradicting, I'd
          like to suggest allowing for a stateSet to be created for those
          situations too. I think that would match the behaviour of
          animation.cxx (PRE_OSG_PLIB_20061029) and is imho the more
          expected and also documented one.

        * simgear/sound/: sample_openal.cxx, sample_openal.hxx,

          JUSTUS: workaround for broken Doppler effect in OpenAL

          mf: this patch is meant to be removed as soon as OpenAL got
          fixed. (The     OpenAL developers acknowleged the bug and
          announced that it'll get     fixed.) For removal try     $ cd
          simgear/sound     $ cvs diff -rAFTER_OPENAL_DOPPLER_WORKAROUND

        * simgear/sound/: sample_openal.cxx, sample_openal.hxx,
          soundmgr_openal.cxx, xmlsound.cxx: Maik JUSTUS: Doppler fixes
          (add option to turn off Doppler for sounds that
          shouldn't be affected -- marker beep, ATIS messages, etc.)

          mf: this is the first part of the original patch. It is supposed
          to contain     fixes that are not caused by OpenAL bugs, and thus
          aren't meant to be     reverted later. The second part will
          contain a temprary workaround for     OpenAL bugs. Unfortunately,
          I had to do the split myself as the contributor     refused to do
          it.

        * simgear/props/: props.cxx: - close loophole through which one
          could sneak in illegal property names   containing slashes,
          colons and all sorts of evil characters. In Nasal   this could be
          done via props.globals.getChild("1!@#$//[]{}", 0, 1).setValue(0);
          The cause is that getChild() hands the given name directly over
          to an   alternative SGPropertyNode ("convenience") constructor
          which sets the   name without any checks.  - unify exception
          messages: first character is lower case

        * simgear/scene/model/shadanim.cxx: allocate W*H*4 bytes (rather
          than W*H*3), as it turned out that glGetTexImage() returns that
          much for the default red/white chequer texture, which is used
          when the requested texture couldn't be found.  This could be a
          bug in the implementation (nvidia/100.14.11/Linux x86) or be
          normal for compressed textures
          (GL_COMPRESSED_RGBA_S3TC_DXT5_EXT).  The OSG developers aren't
          sure about their sizes either (see comment in src/osg/Image.cpp,
          revision 7067: computePixelSizeInBits()).

          for the 2x2 RGB red/white chequer texture:

                0 1 2 3 4 5 6 7 8 9 a b c d e f
            IN: ff0000ffffffffffffff0000          (see
          src/ssg/ssgLoadTexture)
           OUT: f70000ffffff....fffffff70000....

          where the positions marked with a dot remained untouched.

          JUSTUS:

          "[...] switches of the Doppler calculation of OpenAL and adds a
          own Doppler calculation."

          mf: necessary because OpenAL Doppler on Windows is broken, which
          the     openal developers acknowledge. The source revisions
          before and after     the patch was applied are tagged with
          BEFORE_OPENAL_WORKAROUND and     AFTER_OPENAL_WORKAROUND, so that
          one can easier find and remove     the changes if required
          (which is quite unlikely. :-)

        * simgear/timing/: lowleveltime.cxx, timezone.cxx: replace exit()
          by throw sg_exception(). Of course, we have to be aware that
          interdependencies between sg libs are generally unwelcome, but
          sg_exception is a rather basic part, and it's already used by
          xml, props, scene, sound and, of course, structure. Since props
          and xml are core libs, we can assume that sg_exceptions are
          available.  (OK'ed by Curt)

          feature than they were two years or something ago, and it's
          helpful for debugging and exploration to get this important node
          property shown in property tree dumps or in the property browser
          (verbose mode).

        * simgear/props/: props_io.cxx: - fix bug where a property tree
          saved with writeProperties() and read back   in with
          readProperties() would not look the same, because element indices
            of '0' were even dropped when a node has a "secret" value *and*
          children

          - introduce "omit-node" modifier attribute for the "include"
          attribute.    This inserts the given file in place of the
          including node, while the    node is dropped. This is desirable
          for multiple includes (which can't    be done by multiply using
          the "include" attribute, as this isn't valid    XML spec syntax)

        * simgear/nasal/mathlib.c: Melchior points out that NaN/Inf

          ("floating point error") when any of the math library functions
          produce a non-finite value.  Note that these are not the only
          locations that can do that (simply dividing by zero will produce
          an Inf), but it's still proper behavior.

          thread-posix.c, thread-win32.c, threadlib.c, utf8lib.c, vector.c:
          Sync with Nasal CVS (soon to become Nasal 1.1).  Notable new
          features:

          Nasal now supports calls to "subcontexts" and errors can be
          thrown across them, leading to complete stack traces when call()
          is used, instead of the truncated ones we now see.

          Vectors can now be concatenated using the ~ operator that used to
          work only for strings.

          Better runtime error messages in general due to a fancier
          naRuntimeError() implementation

          A big data size shrink on 64 bit systems; the size of a naRef
          dropped by a factor of two.

          "Braceless code blocks" have been added to the parser, so you can
          write expressions like "if(a) b();" just like in C.  Note that
          there's still a parser bug in there that fails when you nest a
          braced block within a braceless one.

          Character constants that appear in Nasal source code can now be
          literal multibyte UTF8 characters (this was always supported for
          string literals, but character constants were forced to be a
          single byte).

          New modules: "bits", "thread", "utf8" and (gulp...) "io".  The
          bits library might be useful to FlightGear, the utf8 one probably
          not as Plib does not support wide character text rendering.  The
          thread library will work fine for spawning threads to do Nasal
          stuff, but obviously contact with the rest of FlightGear must be
          hand-synchronized as FlightGear isn't threadsafe.  The io library
          is no doubt the most useful, as it exposes all the basic stdio.h
          facilities; it's also frighteningly dangerous when combined with
          networked code...

            </model>

          Of course, one could add "select" animations for all
          <object-name> in the <model>, but this is tedious and can hardly
          be done e.g. for all objects in all instruments in
          $FG_ROOT/Aircraft/Instruments-3d/ etc.

          The feature will be used in the bo105, so that civilian variants
          can have a HSI instrument, where military variants have a TACAN
          etc.

2006-07-03 07:13  andy

        * simgear/nasal/: code.c, code.h, codegen.c, gc.c, lib.c, vector.c:
          Been hacking at Nasal recently:

          Fix bug with break/continue inside of a foreach or forindex:
          Don't pop the vector/index inside OP_EACH, do it at the end of
          the loop.

          In the process, discovered and fixed a scary corruption issue
          with continue; it never really worked right, although simple
          usage was likely to get away without crashing.  Both the
          continue's OP_BREAK and the cleanup code at the end of a loop
          would pop the "mark" stack, leading to an underflow.  Introduced
          an OP_CONTINUE which adjusts stack but doesn't change markTop

          Re-inline the PUSH macro.  This thing is called all over the
          place from the inner loop.  If the problem is intra-expression
          side effects, then just use another expression in the macro.

          Return an empty vector when requesting zero-length subvec, not
          nil

          Have call() return the call stack in the error vector; see docs
          on plausible.org/nasal or ask Andy about this feature.

          Default closure()'s level argument to zero, not nil

        * simgear/nasal/lib.c: Oops, implement the previously-mentioned fix
          without breaking support for omitting a length argument to mean
          "the rest of the vector".

2006-03-21 23:22  andy

        * simgear/nasal/lib.c: The original code (rather oddly) interprets
          a length of zero in subvec() to mean "the whole vector".
          Melchior showed a use case (removal of the first element from a
          vector) where getting a zero-length subvector is actually
          desired.  And since I can't come up with a good reason for why
          the "feature" was there in the first place, out it goes...

2006-03-21 22:57  andy

        * simgear/nasal/lib.c: Melchior discovered that cmp() was just
          wrong, failing to actually inspect the string pointers.  It also
          failed to properly sort strings where one is a prefix of the
          other.  It looks to me like I just never finished this, and it
          ended up in CVS because it just happened to compile...

2006-03-15 20:42  andy

        * simgear/nasal/: Makefile.am, bitslib.c, iolib.c: Fix broken
          checkin in iolib.c.  Also add the 'bits' library, which has a
          buf() function needed to make convenient use of io.read().

2006-03-15 20:35  andy

        * simgear/nasal/iolib.c: Melchior found the first bug -- report EOF

          from losing nodes, because other processes removed them (We are
          currently getting a lot of aborts in the condition code when
          running MP. I don't expect this to fix it, but a bug is a bug.)

          (reviewed by Fred, who also fixed *my* bugs :-)

2006-03-12 19:56  mfranz

        * simgear/scene/model/model.cxx: Better use a node that is very
          clearly not used by other services (e.g. animations). The data
          class doesn't mind.

2006-03-12 11:09  mfranz

        * simgear/scene/model/model.cxx: activate model load/unload
          callback again. It turned out *not* to be the cause for the MP
          crashes -- the same crashes did still occur without it.

        * simgear/screen/: RenderTexture.cpp, RenderTexture.h,
          extensions.hxx: Alexander Powell:

          Add MAC OS X Render Texture support:

          Most texture modes seem to work on my Powerbook, but I don't have
          a wide array of machines to test it on otherwise.

          If you have problems, please let me know and I'll see if I can
          help track down the source of the bug.  I'd love to keep working
          on it if time permits (I use RenderTexture in a few other
          projects), so I'll keep you informed if there are any changes
          that I make for the better.

2006-03-09 10:03  mfranz

        * simgear/scene/: material/matmodel.cxx, model/model.cxx,
          model/model.hxx, model/modellib.cxx, model/modellib.hxx:
          model.[ch]xx:   add abstract class SGModelData. If a pointer to
          such a class is handed over   to sgLoad3DModel, then its
          modelLoaded() method is called with path, property   node and
          branch. And then it's added to the scene graph so that it's
          destroyed when the model branch is removed from the graph.

          modellib.[ch]xx:   only cache objects when asked to. This is the
          case for OBJECT_SHARED   and random objects (like before), but no
          longer for OBJECT_STATIC.    These are now removed from the graph
          when they are "out of sight". This    prevents accumulation of
          static models, and makes destroying model data    possible (e.g.
          removing Nasal modules)

          matmodel.cxx:   set cache flag for random objects (same behavior
          as before)

          This patch makes use of the vectors now available in simgear with
          that past patch. And using that it simplyfies the carrier code
          somehow.

          - Small additional factory's to the quaternion code are done in
          the simgear   part. Also more explicit unit names in the factory
          functions.  - The flightgear part makes use of them and
          simplyfies some computations   especially in the carrier code.  -
          The data part fixes the coordinate frames I used for the park
          positions in   the carrier to match the usual ones. I believed
          that I had done so, but it   was definitly different. Also there
          are more parking positions avaliable now.

          was compiled with newer gcc versions (e.g. gcc 4.0.2). These
          compilers implement the c++ standard more strictly, and thus
          don't guarantee that c-style casted pointers to different data
          types really point to the same address. This is only guaranteed
          for union members.

          The patch adds a vector lib I have put together during the last
          time, it is just handy and interfaces well with s(s)g*. Together
          with some small modifications this will later also interface well
          with OpenSceneGraphs vectors/matrices. Using this vector kernel
          is targeted to have a handy matrix/vector lib available and to
          provide a scenegraph independent vector type for use with a small
          scenegraph wrapper aimed for a smooth transition to
          openscenegraph.

          That vector code also includes an improoved geodetic conversion
          routine I have found some time ago published in the 'journal of
          geodesy' which avoids iterative computations for that purpose.

          Also the geodetic position class is more typesafe and unitsafe
          than the Point3D currently is.

          That part is relatively old and in use in my local trees for
          several months now.

          simgear/math/fastmath.hxx, simgear/nasal/mathlib.c: Olaf Flebbe:

          This patch makesFlightGear at least compile on MSVC. I hope I
          have removed reference of my other local changes. DSP and DSW
          files are included for reference. They have been reconstructed
          with am2dsp.pl. I had to introduce a change to am2dsp because of
          the need of filenames with embedded spaces. (Yuck)

          The major direction is to remove clutter like the
          _USE_MATH_DEFINES and have it on the compiler command line sice
          there is no central include file. You will have to put it on the
          command line for your locale Project files, if it not there,
          already. I added the _CRT_SECURE_NO_DEPRECATE define for 2005,
          since it does no harm to other VC version.

          Third Party Libs like plib, OpenALSDK, freeglut, pthreads-win32,
          zlib are unpacked as is side by side. Only change put the
          includes of OpenAL into include/AL rather directly into include.

        * simgear/props/: props.cxx, props.hxx: Melchior FRANZ:

          add optional arg to SGPropertyNode::addChangeListener that
          triggers the listener function call initially. This is useful for
          cases where a freshly installed listener wants to treat the
          current property value as changed from 'unknown' to the actual
          value right away.

          Examples can be found in the Nasal incarnation setlistener(),
          where we have for example this (in $FG_ROOT/Nasal/gui.nas):

            INIT = func {
                ...
                setlistener("/sim/rendering/fps-display", fpsDisplay);
                if (getprop("/sim/rendering/fps-display")) {
                    fgcommand("dialog-show", props.Node.new({"dialog-name":
          "fps"}));
                }
            }

          That is: we first attach a listener that cares for changes to the
          FPS display switch, but then we have to manually open the dialog
          initially.  That's a duplication of code and could be as simple
          as this (INIT part only):

            INIT = func {
                ...
                setlistener("/sim/rendering/fps-display", fpsDisplay, 1);
            }

          That is: the optional third arg makes fpsDisplay be called
          initially, and then again with every write action. My first
          solution was in the Nasal code only, but Andy (rightfully) says
          that this should rather be in sg.

        * simgear/structure/: event_mgr.cxx, event_mgr.hxx: Architectural
          fix allowing the "tip" popups (FOV, view name, etc...) to pop
          themselves down while the simulator is paused.

          The problem was with the "real time" queue in the event manager,
          causing the third argument of Nasal's settimer() (a flag for "sim
          time") to be ignored.  Inverts the default sense of the argument,
          as there are lots of uses of settimer() in the current code,
          almost none of which want to use real time.

          Note this fix introduces a header file incompatibility in SimGear
          -- be sure to update.

          validity of the pos argument.

          removeChildren() will be used in input.cxx, and a lot in the
          upcoming dynamic new_gui dialogs, which are aiming at replacing
          the hard-coded dialogs. I'll discuss them on the list once the

          Correct the bug in the translate animation where the offset was
          part of the multiplication. It now behaves like all other
          animations: out = (prop * factor) + offset

          I feel strongly that the existing is wrong and must be corrected
          - it is non-op if the offset is zero as I have found to my cost!
          It is just a typo I expect.

          The diff also provides non-op default values for the scale
          animation.

          I've also included Harald's latest eye-candy animation which
          allows us to have a very smart heat-haze for exhausts. They have
          been tested by me and others on Linux and Cygwin. You might like

          The patch to simgear-glxproc.diff changes dlopen to not open a
          specific library.  If it is used with a NULL argument, we just
          get a handle to the current running binary including all loaded
          libraries. This has the advantage that we do not rely on the name
          of libGL on the specific platform.  Also a user can link with his
          own different named libGL or with a static libGL.a

          Then the render texture again ...

          glxQueryVersion turns out to return the  minimum of the client
          libraries glx version and the servers glx version. *All* Xorg
          servers return 1.2 here.  So we never get the glxPBuffer
          functions  which are the only ones working with ati's drivers ...
           Reverted back to checking the required functions and just use
          them if they are there. Still prefering the glx standard variants
          since they work on ati's drivers ...

        * simgear/scene/model/: animation.cxx, animation.hxx, model.cxx,
          shadowvolume.cxx, shadowvolume.hxx: Harald JOHSEN:

          Changes =======

          - shadowvolume.cxx, renderer.cxx :   - reduced the polygon offset
          a bit to eliminate some artifact ;   - changed again the cleanup
          code for objects inside a tile because it could crash on rare
          occasion ;   - the culling of shadow casters has been rewritten
          to traverse the scene graph, it should be     a bit faster when
          there is a lot of objects ;   - the range selector was not
          correctly handled, sometimes the wrong LOD was casting shadows.
           - added the option to display aircraft's transparent objects
          after the shadows, this will      reduce the problem of shadows
          being hidden by the transparent object (propeller disk,
          rotor, etc). A side effect is that aircraft's transparent objects
          won't receive shadows      anymore. This is usually a good thing
          except when the aircraft use a 'transparent'      texture where
          it should not. A transparent texture in the plib context is a
          texture      with an alpha channel or a material with alpha <=
          0.99.

          - model.cxx, animation.cxx, shadowvolume.cxx :   - added an

          - shadow volume vertex are now shared, using DrawElements instead

          channel instead of the stencill   buffer.  - releasing memory
          when tiles objects are destroyed - objects sub parts will not
          cast shadows if their name begins with "noshadow"   or if they
          are in a <noshadow> animation

2005-06-27 15:49  ehofman

        * simgear/props/: props.cxx, props.hxx: Melchior FRANZ:

          - introduce removeChildren() and removeChildren(name)  to remove
          all children   or all with a given name - let removeChild() and
          removeChildren() also remove child trees, and let them   return a
          "dirty" boolean that indicates if one or more subnodes had to be
           kept because of refcounting (removeChild returned a
          SGPropertyNode_ptr before) - make alias/unalias increase/decrease
          the refcounter - don't remove refcounted or tied nodes

          This patch makes the SGPropertyNode_ptr actually useful. Until
          today, they did proper refcounting (except for aliases), but no
          other part did check this counter.

          But SGPropertyNode_ptr aren't only useful for the first time,
          they are now highly recommended for every place that relies on a
          node address, and wants to "lock" it (so that removeChild(ren)
          will never try to remove them). This is not guaranteed for
          SGPropertyNode* (and never was). Of course, that's not an
          imminent problem, as only four places currently use
          removeChild(ren) and these are careful to only remove their own
          data.

          Turn the material animation's <transparency> property into a
          group, with members <alpha-prop>/<alpha>, <offset-prop>/<offset>,
          <factor-prop>/<factor>, <min>, and <max>. The "material"
          animation can now fully replace "blend" and "alpha-test" (-->
          <threshold>) animations, with enhanced possibilities: The
          "material" animation can be used for one or more explicit objects
          (like "blend"), but also for all objects that share one material
          (<global>), which avoids problems with objects being forced
          together into one tree. Also, an object doesn't have to be
          semitransparent or textured with a semitransparent texture to
          make blending work. Unlike the "blend" animation, the "material"
          animation also makes fully opaque and untextured objects
          transparent. (This fixes the bo105's formerly semi-transparent
          rotor.)

          depreciated as of now.

          This is another update for the cloud code, a lot of lines but
          this time I have started to add the doxygen doc.

          Misc ====

          - corrected a bug when RTT is not available, the current
          rendering context was   altered - if RTT is not available then 3d
          clouds are not drawn at all - impostors lighting is now
          recomputed when the sun changes position - distant objects are no
          more seen in front of clouds - blending of distant clouds is a
          bit better now - litle optimization of code (uses a less cpu
          time) - use layer wind speed and direction (no more hardcoded
          wind) - fov is no more hardcoded

          Changes =======

          - clouds (cu only) are dissipating/reforming (experimental) -
          compute a turbulence factor that depends on surrounding clouds
          and type of   clouds (experimental) - clouds shapes are defined
          in cloudlayers.xml - type of clouds present in a layer is also
          defined in cloudlayers.xml - cloud layers are generated from
          metar and other misc. data (in progress) - added a rain effect
          around the viewer (enabled in the rendering dialog and   when the
          metar property says so) - added a lightning effect (enabled in
          the rendering dialog) : cb clouds spawn   new lightnings - added
          a dialog to select from different weather source :
          metar/property,   a 'fair weather' environment and a
          'thunderstorm' environment.

        * simgear/props/: props.cxx, props.hxx, props_io.cxx: Melchior
          FRANZ:

          Vivian pointed out that a redefined Ctrl-U key binding didn't
          work correctly. I found out that this is, because the definition
          in $FG_ROOT/keyboard.xml sets <value type="bool"> for binding[1],
          and ... [better sit down first!] ... and assigning <value
          type="double"> in a *-set.xml file doesn't *really* set "double"
          as new type!

          Instead, the boolean is kept, and a double sqeezed into it. In
          other words: once tainted as bool, you can throw all doubles in
          the universe on a property node, and all it will accept is 0 and
          1. Without warning!

          BTW: I changed the patch: I was overly cautious: clear_value()
          does already care for ties and for setting NONE, so we just need
          to make that public as clearValue(), and use that. Makes the
          patch a bit more verbose, though.  :-/

        * simgear/bucket/newbucket.cxx: Phil Cazzola:

          This is a minor bug fix for sgBucketDiff().  If you crossed the
          bucket size boundary, the answer for dx could be wrong.

          E.g.   going from   0:0, 21:7  to 0:7, 21:7   would give you dx =
          7 (correct)   but going from 0:0, 21:7 to 0:3, 22:0 would give
          you dx = 6 (instead of 7)

          Previously it differenced the center longitudes of the buckets.
          When you cross a boundary, the center point of the larger bucket
          now lies on the edge of the smaller bucket.

          The result was a dx with an integer + 1/2 bucket, which rint()
          was rounding to the nearest even int.

          This function only seems to be used in TerraGear.

        * simgear/scene/model/: placementtrans.cxx, placementtrans.hxx:
          Mathias:

          I have done a patch to eliminate the jitter of 3D-objects near
          the viewpoint (for example 3D cockpit objects).  The problem is
          the roundoff accuracy of the float values used in the scenegraph
          together with the transforms of the eyepoint relative to the
          scenery center.

          The solution will be to move the scenery center near the view
          point.  This way floats relative accuracy is enough to show a
          stable picture.

          To get that right I have introduced a transform node for the
          scenegraph which is responsible for that shift and uses double
          values as long as possible.  The scenery subsystem now has a list
          of all those transforms required to place objects in the world
          and will tell all those transforms that the scenery center has
          changed when the set_scenery_center() of the scenery subsystem is
          called.  The problem was not solvable by SGModelPlacement and
          SGLocation, since not all objects, especially the scenery, are
          placed using these classes.

          The first approach was to have the scenery center exactly at the
          eyepoint.  This works well for the cockpit.  But then the ground
          jitters a bit below the aircraft. With our default views you
          can't see that, but that F-18 has a camera view below the left
          engine intake with the nose gear and the ground in its field of
          view, here I could see that.  Having the scenery center constant
          will still have this roundoff problems, but like it is now too,
          the roundoff error here is exactly the same in each frame, so you
          will not notice any jitter.

          The real solution is now to keep the scenery center constant as
          long as it is in a ball of 30m radius around the view point. If
          the scenery center is outside this ball, just put it at the view
          point.

          As a sideeffect of now beeing able to switch the scenery center
          in the whole scenegraph with one function call, I was able to
          remove a one half of a problem when switching views, where the
          scenery center was far off for one or two frames past switching
          from one view to the next. Also included is a fix to the other
          half of this problem, where the view position was not yet copied
          into a view when it is switched (at least under glut). This was
          responsible for the 'Error: ...' messages of the cloud subsystem
          when views were switched.

          Changes =======

          - corrected some strange behavior when playing with the render
          dialog options - the density slider is now working : if you are
          fps limited and still want to see clouds in   the distance you
          should play with that - added the choice for texture resolution,
          its more comprehensible now (before it was   wrongly allways
          choosing 64x64 textures) - changed the initial texture size : you
          now have 64 texture of 64x64, this uses 1Mo of   texture memory
          (before it was 20 texture of  256x256, that took more memory and
          there was   not enought impostors) - sun vector is now right so
          the lighting is a bit better - removed useless sort and light
          computations for impostors, this should save a lot of cpu -
          blending of distant cloud is more accurate now - clouds are now
          positioned correctly, they don't try to escape you anymore - no
          more red/white boxes around cloud - textures are now filtered (no
          more big pixels)

          known bugs ==========

          - distant objects are seen in front of clouds

        * simgear/nasal/: code.c, code.h, codegen.c, lex.c, lib.c, parse.c,

          analagous to foreach, except that the variable gets the index
          instead of the list element.  Should be useful, and took almost
          no code to implement.

          Support for operator/assignment syntax: +=, -=, *=, /= and ~= now
          do what you think they should.

          Library support for a bind() function (see the docs Andy is still
          writing), allowing runtime modifications to function lexical
          environments.

          Augment the find() function to take a starting index.  Fix strc()
          to use a default index of zero.  Fix parser precedence of

        * simgear/scene/model/: animation.cxx, animation.hxx, model.cxx,
          model.hxx: Melchior FRANZ:

          here is the promised material animation. It looks a bit longish,
          but that wasn't avoidable -- there are simply too many parameters
          to consider. I tried hard, though, to make the animation fast by
          only doing the necessary stuff.  It doesn't affect the frame rate
          here with my test model. The animation is heavily based on Jim's
          "material-emission" animation.

          * implementation of the "material" animation (this required to
          make the   texture path available) + documentation update
          ($FG_ROOT/Docs/) * fix some more return values (texture
          animations, and select) for the   shadow problem (and some in
          anticipation of other problems  :-) * fix compiler warning

2005-03-19 11:19  ehofman

        * simgear/scene/model/animation.cxx: Melchior FRANZ:

          the cause for the disappearing shadows is, that SimGear doesn't
          tell plib to call the pre-traversal-callback function on culled
          objects. These calls, however, are necessary to execute the
          transform animation that does, for example, translate a shadow
          back into the frustum! Curretnly, the callback is only executed,
          and the shadow only magically pops up again, when the object
          enters the frustum because the view has changed significantly.

          The plib documentation does only talk about TRUE and FALSE for
          possible return values from the pre-traversal-callback. But
          src/ssgEntity.cxx reads like this:

             int ssgEntity::preTravTests ( int *test_needed, int which )
             ...
                 int result = (*preTravCB)(this,which) ;

                 if ( result == 0 ) return FALSE ;
                 if ( result == 2 ) *test_needed = 0 ;
             ...

          So the return value needs to be 2 to bypass the cull test for
          pretraversal, and get the pretraversal in any case. I only
          changed the return values in four animations: scale, rotate,
          translate, and range, because these are the most likely to move
          an object out of the frustum. It's not necessary for
          blend/alpha/texture manipulation etc. Of course, this is a bit
          more work for plib, but the performance will probably not be
          affected, because:

          * these four animations are mainly used for the aircraft model
          (the spin   and billboard (trees!) animations are not affected)

          * the number of extra nodes to process is quite low

          * a part of the time spent for the extra nodes to be processed,
          was before   used for workarounds that are now not necessary any
          more

          I didn't observe a frame rate drop, at least.

          same numerical value.

2005-03-11 20:07  andy

        * simgear/nasal/: codegen.c, parse.h, string.c: Don't parse the
          strings "+" and "-" as numerical zeros.  Also fix the code
          generation of constant objects to use real identity and not Nasal
          equality, so (e.g.) the constants 1 (number) and "1.0" (string)
          do not get turned into the same object in the generated code.

2005-01-29 11:31  ehofman

        * simgear/scene/model/: animation.cxx, animation.hxx, model.cxx:
          Jim Wilson:

          This patch adds support to the model animation system for
          modifying emissive states on the fly so that it is possible to
          make "lights" appear to dimm.

          This is an example of a configuration entry which should explain
          how it is used:

           <animation>
            <type>material-emission</type>
            <object-name>Face</object-name>
            <property>/controls/lighting/instruments-norm</property>
            <emiss-red>1.0</emiss-red>
            <emiss-green>0.8</emiss-green>
            <emiss-blue>0.5</emiss-blue>
           </animation>

          Note the color entries are the emissive colors when the
          "property" value is 1.0.  They are useful for tinting the light.
           The "property" itself must be float or double and is clamped to
          values between 0 ~ 1.0 inclusively.   The "property" value is
          multiplied against the colors to get the actual material
          properties.  Thus property value 0.0 = darkest, and 1.0 =
          brightest.

        * simgear/sound/soundmgr_openal.cxx: Melchior FRANZ:

          If alcOpenDevice( NULL ) is NULL, then context is never assigned
          a value, and it's pointless to ask for it in the next "if". But
          as the ALCcontext that context points to doesn't seem to be fully
          defined (OpenAL bug), valgrind still complains ...

          Erik Hofman: Extend this some further and define context=0
          otherwise and check for context != 0 before using it.

2005-01-27 11:42  ehofman

        * simgear/screen/texture.cxx: Melchior FRANZ:

          Trying to find the bug in tower.cxx (that crashes fgfs quite
          frequently for me!), I'm playing with valgrind again. Until I'm
          in the ATC subsystem there will be some other bugs and nitpicking
          along the way.

          valgrind doesn't like that imgage->tmp is once allocated with new
          and once with new[], sometimes with malloc() (via map), and
          sometimes freed with delete (not delete[]!) and sometimes with
          free(). With simple types such as GLubyte this shouldn't really
          make a difference, but anyway.

          Also, I promised that I'd send patches for "if (foo) delete foo;"
          as I'm making other changes to concerned files. texture.cxx is
          one with a few occurrences thereof. (Remember: C++ explicitly
          allows to delete null-pointers, so this check is redundant, and
          hence not tolerated in other projects, such as KDE. Doesn't have
          to impress us, of course.  :-)

          Also, fixes 4 signed/unsigned warnings (gcc 3.3.4)

        * simgear/nasal/code.c: Move error handling in setupFuncall above

          enclosing scope, not the called (non-)function.  This bug was
          fixed a few months back in my private tree, but Melchior just
          discovered that the new Concorde scripts tickle it.  I really
          need to re-synchronize SimGear with my own Nasal tree...

        * simgear/scene/sky/: cloud.cxx, sky.cxx: - Fix a couple oops's in
          cloud.cxx - In sky.cxx blend low density cloud layers
          (few/scattered) into nothing (but   don't touch visibility
          distance) as we approach them so we can fly through   clean.  -
          For high density cloud layers (broken/overcast) we do not fade
          the layers   out, but we fade visibility to nearly nothing as we
          approach the layer.

          We use this effect in combination with lowering visibility as we
          approach a cloud layer to hide the fact that it is simply a 2d
          textured polygon being drawn across the sky.

          FRANZ:

          My recent fix for the load/save fgfs.sav feature was a bit too
          ambitious.  While aliases lead to abortion before, I tried to
          copy them properly, although this wasn't a requirement.
          Unfortunately, this seems to have worked for absolute aliases
          only, not for relative ones, and hence broke several panel
          instruments. The attached patch backs most of the previous patch
          out again, and goes a simpler route: just ignore aliases.

2004-12-19 11:19  ehofman

        * simgear/props/: props.cxx, props.hxx, props_io.cxx: Melchior
          FRANZ:

          fgLoadFlight() loads a property file ("fgfs.sav") to a new
          property tree, and then copies that over to the main tree.
          copyProperties() didn't know how to handle type
          SGPropertyNode::ALIAS and hence threw an exception that made fgfs
          abort.

          The attached patch adds support for ALIAS to copyProperties():
          aliased nodes are created in the target tree if necessary, and
          then linked like in the source tree. It seemed useful to add an
          optional argument to props.[ch]xx/getType() that would indeed
          return the property type "ALIAS" for aliased nodes, and not the
          type of the node that it refers to. The patch also fixes a bug in
          writeNode() that caused extra lines after alias entries.

          If there's resistance to the change to getType() (David?) I can
          easily use isAlias(). This just makes copyProperties() a tad
          uglier, but I can live with it. It's useful for scanning a tree,
          though, if an alias node can be treated exactly like all other
          nodes, without automatic redirection.

          At last I've found the reason why fgfs crashed routinely for me.
          When I still used KDE's artsdsp (preloads lib with OSS
          replacement functions) I saw this crash only occasionally. After
          letting OpenAl communicate with artsd directly (by means of
          ~/.openalrc setting), I got the crash always when I left fgfs.

          model/model.cxx: Frederic Bouvier:

          I was not very happy with the size of the halo, so I created a
          new animation to control it. Now we can control the scale value
          with the distance from the viewer to the object. The towers are
          now beginning to look good. They might need some tuning though.
          If you want to play, locate in radio-*.xml this code :

           <animation>
            <type>dist-scale</type>
            <object-name>RedLight.2</object-name>
            <interpolation>
             <entry><ind>0</ind><dep>0.1</dep></entry>
             <entry><ind>500</ind><dep>0.3</dep></entry>
             <entry><ind>16000</ind><dep>3</dep></entry>
            </interpolation>
           </animation>

          You get the idea ? ind is the distance, dep is the resulting
          scale value.  The medium tower appears brighter than the tall
          one, because the lights are closer to each other. Maybe they need
          a smaller scale factor at distance. Feel free to modify these
          values if you find a better setup.

          About the code : I renamed flash to custtrans because the ssg
          branch is now less specialized. It needs a callback to compute
          the so called 'custom transformation'. It can be used for the
          SGFlashAnimation and the new SGDistScaleAnimation. So please cvs
          remove flash.[ch]xx and add custtrans.[ch]xx. I also undo some of
          the code I send you yesterday that was totally useless. It is
          replaced by something simpler and that works.

          There is also a patch to matmodel.cxx. This is not related and
          was something I forgot. Its purpose is to set the alpha test on
          material billboard models that are likely to be trees to lessen a
          transparency weird effect with clouds.

          period is also random as you noticed. I also put all the flashing
          light of the pole in the same animation so they flash in the same
          rhythm.

          I have 2 new files : personality.[ch]xx . They store the
          personality data that would be deleted when the object is
          destroyed, instead of staying in the animation maps. I also
          manage the current animation step better and the towers are not
          flashing randomly now.  Makefile.am is updated.

        * simgear/scene/model/: animation.cxx, animation.hxx, flash.cxx,
          flash.hxx, modellib.cxx: Frederic Bouvier:

          modellib.cxx :   Add a branch between the model and its
          transformation to add  a unique identifier for the model. I
          called it "personality  branch" and it maintains a
          "current_object" in SGAnimation.   Animations specifically
          written to support it ( currently only   the timed animation )
          can add a degree of variety among the   occurrences of the same
          model that would look otherwise cloned.

          flash.[ch]xx :   Better compute the view vector. The flash is now
          syncronized with  its axis even at the edge of the screen.

          animation.[ch]xx :   Lots of changes :  - add a condition to
          'rotate', 'spin', 'translate' and 'range'.    When a condition is
          specified *and* it evaluates to false, the    animation becomes a
          no-op. Possible usage : no rotation during    daylight, LOD range
          variable along the day, ...

           - use different durations for each branch in the timed
          animation.
            Enable the use of multiple <branch-duration-sec>, one for each
            <object-name> specified. Usage : strobes with flash light.

           - allow randomization of the <branch-duration-sec>, by using
            <random><min>_min_value_</min><max>_max_value_</max></random>.
            The value computed once is between _min_value_ and _max_value_.

           - implement model personality in timed animation. If
            <use-personality type="bool">true</use-personality> is
          specified,
            a different set of duration is created for every model in the
            scenegraph using this animation. Best if used with
          randomization.
            When using strobes where the population of the same object is
            dense, it avoids the "cheasy" clone effect.

        * simgear/scene/model/: Makefile.am, animation.cxx, animation.hxx,
          flash.cxx, flash.hxx, model.cxx: Frederic Bouvier:

          this patch introduce a new kind of animation and ssg branch.  I
          called them flash animation, because they help me to enhance the
          look of the rotating beacon and possible future lighthouse. It
          computes the cosine of the angle between an arbitrary axis,
          transformed by the current modelview matrix, and the view
          direction. No trig involved, just a dot/scalar product.

          The computed value can be modified by three parameters, power,
          factor and offset, according to the formulae :

           value = factor * pow( cosine, power ) + offset.

          It is clamped between a minimum and a maximum.  This value is
          then used as the scale factor of a matrix transformation applied
          to the children of the SGFlash branch.

          The xml syntax, with default values, is :

          <animation>  <type>flash</type>
          <object-name>HaloObject</object-name>  <center>   <x-m>0</x-m>
          <y-m>0</y-m>   <z-m>0</z-m>  </center>  <axis>   <x>0</x>
          <y>0</y>   <z>1</z>  </axis>  <power>1</power>
          <factor>1</factor>  <offset>0</offset>  <min>0</min>
          <max>1</max>  <two-sides>false</two-sides> </animation>

        * simgear/scene/sky/: cloud.cxx, cloud.hxx, sky.cxx: Frederic
          Bouvier:

          This is a new patch that allow to define a different texture for
          top and bottom of clouds. It uses the overcast_top.rgb you made
          for me last time.

          What the patch do is to install a ssgStateSelector instead of a
          ssgSimpleState for each layer.  The SGCloudLayer::draw method is
          modified to accept a boolean that will select the proper state:
          0/false for bottom, 1/true for top.

          Then, in SGSky::drawUpperClouds and SGSky::drawLowerClouds,
          SGCloudLayer::draw is called with false and true because we see
          the bottom of upper clouds and the top of lower clouds.

          Only overcast has 2 textures, the other types share the same
          state for top and bottom, but that could be modified in
          SGCloudLayer::rebuild.

        * simgear/scene/tgdb/obj.cxx: Frederic Bouvier:

           put all leaf is a seperated branch so that it is
           possible to use a pretrav callback to cull out
           terrain without culling out light or dynamic
           objects. It appears that plib is not calling the
           pretrav callback for leaves.

           add an optional parameter that would be called to
           build the aircraft panel, so that flightgear's
           model_panel no longer duplicate code.

           add a pretrav callback to models so that we can
           filter out models when calling ssgCullAndDraw on
           the global scene.
           sgSetModelFilter( true ) means that we want to draw
           the models. Use false to cull them out.

        * simgear/scene/model/location.cxx: Frederic Bouvier:

          The message 'Alert: catching up on tile delete queue' comes from
          the fact that 48 tiles are scheduled and added to the cache at
          startup before the plane location is initialized. My proposed
          patch is to initialize SGLocation with an invalid position and
          detect this fact before scheduling tiles. I prefer to do that
          rather than testing for lon and lat being 0,0 because it is a
          valid position and someone could want to fly near Accra.

          It seems that this animation refers to 'PanelInstruments' that is
          a panel outside the model, so, when loaded with
          SGModelLib::load_model the object is not found in the model and
          there is a non tested read access through a null pointer in
          sgMakeAnimation.

          mix between fg-root, fg-scenery and PLIB's model-dir.  It has
          been reported on the list that users are not able to see the
          buildings, especially those running the win32 builds because they
          run 'runfgfs.bat' that set FG_ROOT=./DATA.

          I decided not to use model-dir because it just add confusion and
          to build a valid path earlier.

2003-07-10 11:49  ehofman

        * simgear/scene/model/: animation.cxx, animation.hxx, model.cxx:
          Jim Wilson: This update adds the ability to do multiple texture
          transforms (Steve B. thinks supporting them at the plib level
          would be inefficient, which is probably true).

          Removed units (e.g. "_m") from texture translation property and
          variable names since the texture translation values are
          dimensionless.

          Added the ability to specify a scroll factor for stepped texture
          animation that needs to scroll smoothly when approaching the step
          interval (e.g. odometer movement).

          doxygen main page.  - Added documentation for SGCloudLayer -
          Updated the SGSky interface a bit to make it more sensible,
          flexible,   and generic.  This requires a code tweak on the
          FlightGear side as well.

        * simgear/: scene/sky/dome.cxx, timing/sg_time.cxx,
          timing/sg_time.hxx: Make sky dome scaling values sensible (i.e.
          the sky dome will now fill up   the dimensions provided.)  We
          draw the sky dome before everything else   and draw it with depth
          buffer off so it really doesn't matter, but it just   makes a
          little more sense this way.  Updated a few doxygen comments.

        * simgear/scene/model/: animation.cxx, animation.hxx: Add the
          ability to include stepped texture translations for things like
          digital displays in 3D model animation.

2003-06-08 15:19  ehofman

        * simgear/scene/model/: animation.cxx, animation.hxx, model.cxx:
          Jim Wilson: 1. Added support for defining arbitrary rotation axes
          using (x1,y1,z1), (x2,y2,z2).  The center is calculated
          automatically (midpoint on line) or you may specify an alternate
          "center" using the current scheme.  This makes it about  100
          times easier to animate flaps, ailerons, etc.

          2. Added support for plib's ssgTexTrans.  This will allow more
          sophisticated 3D instrument features by allowing the texture
          mapping itself to be animated. Included function for "texrotate"
          and "textranslate".  They configure the same as the geometry,
          except the arbitrary axis definition is not necessary (textures
          are flat).

          getting promoted to an int so it would match a method with a
          const SGPropertyNode * as the first argument.  But that made it
          match the wrong version of prop->getNode() and things were

          dependencies on flightgear's global   state (all the globals->
          stuff, the flightgear property tree, etc.)  SimGear   code can't
          depend on it so that data has to be passed as parameters to the
          functions/methods/constructors.

          This patch adds some missing default ISO C++ headers to SimGear,
          especially usefull for Irix/MipsPro. To the best of my knowledge
          this only affects the Irix/MipsPro compiler combination although
          it might be usefull for others as well.

          This patch does not yet remove any compiler specific code, but
          that would be my next task. The powerfull macros as defined in
          the compiler.h file allowed me to split it up into multiple
          patches.

        * configure.ac: James Turner:

          I've had to hack Simgear's configure.ac quite a bit [for Mac OS
          X], using the Plib one as a reference.  The basic construct (a
          big switch statement based on the target type) is nice, I think,
          since it moves lots of IRIX / cygwin / OS-X specialties out of
          the way cleanly. Much more re-factoring of the current tests in
          configure is possible if people are able to test.
