589 tree and examine and even change values, all from a remote computer.
590 * Improvements to flight model initialization.
591 * Fixes and improvements to the save/restore code.
592 * Added a load/save dialog box for saving/restoring your current flight.
593 * Program notes max texture size for your card/driver so it can load
594 higher resultion textures if they are available and if you can use
596 * Added a visibility= command line option for setting intial visibility
598 * Range of tiles loaded and drawn are now directly calculated from the current
599 visibility distance so that the ground always blends smoothly into sky.
600 * Rewrote the tile caching scheme so it is now more flexible, more dynamic,
601 simpler, and more robust.
602 * Updates to the FDM bus.
603 * Many clean ups with the view code to prepare the way for a greater
604 variety of external views.
605 * MSVC project files now included in the source distribution.
606 * Fixed a view bug that could make the aircraft model appear rotated
608 * Fixed a bug with the autopilot rate of climb hold.
609 * Internal property manager tweaks.
610 * Additional materials can be aliased to an existing material to save
611 texture space (at the expense of less texture variety)
617 * Aircraft now starts at end of runway closest to desired heading.
618 * Runways now have accurate markings.
619 * Addition of a completely reconfigurable instrument panel.
620 * Tons of panel tweaks and fixes. Gyro now drifts, relocated whisky compass,

630 * Fixed a couple namespace problems.
631 * MacOS and MSVC tweaks.
632 * Renamed JSBsim to JSBSim
633 * Added support in the material library for non-repeating textures.
638 * VOR reception now scales with altitude.

649 * Fixes to uiuc includes and initializations
650 * Fixes to periodic scheduler.
651 * Fixed a tile loading bug if the load queue wasn't empty before a reset or
654 * Some additional MSVC5 portability fixes.
655 * Tweaks to build with newest gcc under Irix contributed by Erik Hofman.
657 * Clean out a pile of old junk in the material manager library from the
658 pre-ssg days, and majorly overhauled it.
659 * Complete reengineering of the panel code in preparation for moving the
660 configuration out into a data file.
661 * Lots of hashing around with Joystick support trying to achieve something
662 that is flexible enough to handle the zillions of possible configurations
663 out there. Hopefully we are approaching a workable solution.
664 * Better windows support in our joystick module.
665 * View code simplifications and optimizations contributed by Norman Vine.
667 * Added support for $FG_SCENERY and --fg-scenery=path so scenery can have a
668 different location from the base package.
669 * Moved drop in sky module, world time module, ephemeris module, and low
670 level communications modules over to simgear.
671 * Replaced gdbm with metakit
672 * Added David Megginson's property manager
677 * Added a radio stack 2 VOR/ILS and an ADF to the instrument panel.

689 * Autopilot now has modes to track a VOR and GS.
690 * Added custom joystick client support so sim can be flown from a
691 remote joystick connected to another machine. This is in support of
692 some custom hardware located in the human factors research lab of the
693 university of minnesota.
694 * HUD controls are a bit different "h" toggles through day/night/off
695 modes and "H" cycles through brightness levels.
696 * Norman Vine contributed code to optionally do antialiased hud lines
697 on hardware that supports this. Norman also contributed additional
698 hud cleanups and updates.
699 * Updates to JSBsim flight dynamics code that includes a generic
700 reconfigurable flight control system, a initial state trimming routine,
701 support for wind and weather, support for flaps, independent trim control,
703 * Updates to LaRCsim flight dynamcis code contributed by UIUC that
704 allows loading aircraft specifications at runtime from config files.
705 UIUC is using flightgear as a platform to do icing research. The UIUC
706 aircraft use the c172 gear model for now which causes some weirdness
707 on the ground for some of the larger aircraft.
708 * Flight model no longer has to be chosen at compile time.
709 * Separated ephemeris code from the actual sky rendering code and gave
710 this whole section a big overhaul. The moon should now consistantly
711 have the correct phase.
712 * Rebuilt the sky dome using ssg.
713 * Removed dependencies on mat3.h and friends (old srgp support lib)
714 * Airport lookups now done through gdbm (a light weight embedded database.)
715 * Converted ssgVTable's to ssgVtxTables which do proper memory
716 management and should facilitate use of compiled vertex arrays once
717 ssg add support for these.
718 * Overhauled autopilot internals, separated out the gui controls from
719 the actual autopilot code.
720 * Cygwin32 build fixes
726 * Lots of code reorganizations
727 * Build requires plib-1.1.x
728 * Build requires SimGear-0.0.x
729 * LaRCsim/c172 is now the default aircraft model.
730 * Added flaps support to control model.
731 * Lots of updates and tweaks for the LaRCsim/c172 model.
732 * Use a more standard texture/blend mode combination for sun/moon halos to
733 avoid render path that's not supported by all cards/drivers.
734 * Change reported speed on hud from V_equiv_kts to V_calibrated_kts
735 * Instrument panel rewrite by David Megginson. This isn't quite as flashy
736 as the first pass, but is much more functional, plays much better with
737 opengl, and it should be relatively easy for someone with graphical skills
738 to make it look more spiffy.
739 * MacOS fixes contributed by Darrell Walisser.
740 * Many JSBsim updates.
741 * Added a screen snapshot facility (F3).
742 * Added a load/save state function contributed by David Megginson.
743 * Added support for various I/O protocols and channels so that flightgear
744 can communicate with itself and other programs through a variety of means.
745 * Bug fix: The aircraft model used for external views was being included in
746 the height above terrain check so when the view position and the aircraft
747 model collided the current altitude kept getting pushed up to compensate,
748 but of course the aircraft model would get pushed up as well because it
749 tracks the current aircraft position and orientation. Thus you had a never
751 * Oliver's multiplayer network code now moved to his own subdirectory:
753 * Added simulated cloud puffs as we pass through the cloud layer.
754 * Cleaned up some memory leaks occuring between ssg and flightgear.
755 * Update to Christian's weather data base code.
758 * Durk Talsma added a nifty cloud layer.
759 * Default to Christian Mayer's new weather system.
760 * Added routines to do screen printing contributed by Mark Vallevand.
761 * Added routines to do screen shots to ppm graphics file (all platforms)
762 contributed Rich Kaszeta.
763 * Added a magic carpet (aka slew) mode.
764 * Added a hot air balloon simulator mode. (alpha)
765 * Added a simple (direct lincage) autocoordation feature.
766 * Added a mode to control view (side to side and up and down) with the mouse.
767 * Fixed a DEM decoding problem which caused most of the terrain to be 256
768 meter too high (and regenerated the world scenery with proper elevations.)
770 * Added support for a pilot view offset from the center of gravity.
771 * Various platform portability fixes.
772 * Updated time-offset/syncing command line options.
773 * Updated the FDM <==> Flight Gear interface to be more object oriented.
774 This should hopefully pave the way for being able to simulate several
776 * Removed unimplemented menu entries.
777 * Various scenery tools changes and enhancements in preparation for adding
778 runways (hopefully for the next release.)
781 * Autopilot can now fly great circle routes.
782 * Incorporated a first stab at some networking code contributed by Oliver
784 * Added Christian Mayer's new weather subsystem.
785 * Started adding support for "external" views ... still needs some work.
786 * Added a flight model acceleration funtion.
787 * Added support for mouse yoke control contributed by David Megginson.
788 * FDM model hertz now definable from the command line.
789 * Added initial timezone support so the user can have better control and more
790 options for setting the starting time of the sim.
791 * We now draw nonexistant tiles as ocean which means we only have to create
792 and distribute tiles that contain some sort of land mass.
794 * Replaced basic render engine with plib's ssg (simple scene graph).
795 * Now expect plib to be installed in it's one true and official location.
796 * Added support for timegm() if it exists which explicitely expects GMT input.
797 * A bit of your basic code reorganization and shuffling.
799 * Removed tools dependency on libgfc. Functionality is now covered by
800 shapelib which has been added into the Tools tree.
801 * Added support for the wonderful GSHHS global land mass data set.
802 * Removed dependecy on process-dem.pl script.
803 * Created a new distributed/parallel tile build system ... hmmm kind of super
804 computer or beowulf style stuff for getting large chunks of scenery built
806 * Only generate tiles that have land mass data since the sim can recreate pure
807 ocean tiles on the fly.
808 * First stab at a water flattening scheme to prevent oceans, lakes, and rivers
809 from running up and down the sides of hills.
810 * Changed the default "Work/" subdirectory layout.
811 * Updates to better handle segment boundaries in preparation for real airport
812 runway and lighting modeling.
813 * Updates and enhancements to my polygon management class.
816 * Updates to Tony's c172 model.

826 fixed, distorted textures have been fixed, real coastlines have been added,
827 and many other subtle improvements.
828 * Tools for parallelizing the scenery building tasks. For instance by using
829 20 machines in parallel, scenery for the entire USA can be regenerated in
830 just over 4 hours vs. 70+ hours on a single machine.
831 * Texture scale can be specified (and changed)( in the materials file. The
832 sim must be rerun for the change to take effect.
833 * Windows now uses plib joystick code so rudder pedals should now work.
834 * Now builds against Steve Baker's plib (portable game devel library)
835 distributed separately (www.woodsoup.org/~sbaker/plib/)
836 * Many source code changes for the MacOS port contributed by Darrell
837 Walisser (the port isn't quite there yet ...)
838 * Source code changes for better compiling with the Borland compiler.
839 * Source code changes for better compiling with the native Irix compilers.
840 * Fixed a bug so you can now fly across the international date line (or
841 more precisely the division between longitude = +/-180.
842 * Tweaks to the Astro section contributed by Durk Talsma.
843 * Autopilot improvements contributed by Norman Vine.
844 * Fonts/characters now drawn with texture maps for increased speed.
845 * Instrument panel can be toggled on and off with "P".

848 faster font drawing for much better performance.
849 * Reset function added to reset you to your starting conditions.
850 * GUI function to enter a new airport id (and be transported there)
851 * Added serial output support for an "in-development" full motion cockpit.
852 * "Just in time" texture loading to reduce initial sim loading time.
855 New in 0.59 (This is an intermediate/stepping stone release. Skip this
856 release if you are interested in stability.)
857 * IRIX portability changes and support for native SGI compilers.
858 * Solaris portability tweaks
859 * Incorporated some MacOS portability changes (although the port is not
861 * Changes to allow adjustment of the autopilot settings while it is
863 * Began complete overhaul of scenery generation tools.
864 * Fixed a view frustum culling bug.
865 * separated lib GPC (generic polygon clipper.) GPC is not "freeware" and
866 the author has explicitely refused our request to distribute source code
867 for this library with Flight Gear.
868 * updated installation and getting started guide
869 * switched to a simpler, lighter weight frame rate calculation method.
870 * new tile division scheme.
871 * GPS serial *output* fixes.
872 * Added a nifty halo to both the sun and moon. Preparation for allowing
873 subtle moon lighting effects at night.
874 * Incorporated Jon Berndt's new C++ flight model rewrite.
875 * Autopilot settings can be adjusted while active.
876 * Updates to the instrument panel.
877 * Fixed AOA reading on the HUD.
878 * Added random splash screens.
879 * Modified scenery loader to accept tri-fans.
880 * Other non-backwards compatible changes to scenery file format and tile
885 * Added JSBsim alpha code ... this is Jon S. Berndts alpha FDM rewrite.
886 Still lots to do, but you can watch a balistic flight for a short time.
887 * Renamed Simulator/Flight to Simulator/FDM
888 * Tweaks to assist building FGFS on solaris platforms.
889 * Moved Lib/DEM to Tools/DEM
890 * Started preparations for scenery generation tools overhaul.
891 * More MSVC++ support.
892 * Removed code that made the sun bigger at the horizon since this is just
893 an optical illusion in real life.
894 * Bug fixed so that the sim can start out at an airport below sea level.
897 * Converted to a simpler frame rate counting method.
898 * Fixed the AOA reading on the HUD.
899 * Removed gpc from the Lib section of distribution by request of the
900 gpc Author. The gpc license is unfortunately not compatible with
901 the GPL. I may look for an alternative library, or just require
902 that developers download this library separately.
903 * First slew of changes from the MacOS porting effort contributed by
904 "Robert Puyol" <puyol@abvent.fr>.
905 * Support for an arbitrary number of serial ports + additional serial port
907 * Serial output tweaks to make things more robust and act more like a GPS.
908 * Portability enhancements for Borland, Solaris, and SGI.
909 * Some internal class renaming and reorganizations. fgFLIGHT becomes FGState.
910 fgCONTROLS becomes FGControls.
911 * Started work on an "external" flight model so the sim can be driven from
912 external input (serial port, network, file, etc.)
913 * Fixed a problem that creeped in with setting the initial startup altitude.
914 This could cause an unrecoverable bounce and you'd end up flipped on your
915 back. Should be fixed now.
916 * Sun now appears to grow in size as it gets very low in the horizon.
917 * Fixed a view frustum culling bug where the scene was not accurately culled
918 when your view was anything other than straight forward.
921 * Changed default HUD units to the more standard feet units. You can still
922 use meters by specifying the command line option "--units-meters".
923 * Added some initial joystick support using Steve's joystick interface class.
924 This works great under Linux, but Steve's class now needs to be ported to
925 Windoze and other platforms.
926 * Also added a fall back to the GLUT joystick routines for windows (until
927 we can find better joystick support.)
928 * Added some initial serial port support for acting like gps and outputing
929 nmea data such that could be fed into a flight map software package.
930 * Miscellaneous code clean ups, portability improvements, and optimizations.
931 * Switched to a streams based error/debug logging system that can be
932 completely stripped out for a release build (./configure --without-logging)
933 * Support for cygwin32 b20 compiler (latest release)
934 * Continued progress on instrument panel
935 * Support for starting fgfs at higher resolutions.
938 * New version of gpc (generic polygon clipping library) from
939 http://www.cs.man.ac.uk/aig/staff/alan/software/
940 * Brakes (use "b" to toggle)
941 * Added an altitude hold module to the autopilot. Lock your current altitude
942 with "ctrl-a", "cntr-a" again will deactivate. (Also lock your current
943 heading with "ctrl-h", and again to deactivate.)
944 * Added a terrain following module ... "ctrl-t" to activate.
945 * Added an autothrottle ... "ctrl-s" to activate.
946 * Fixes so that terrain tools will work in windoze.
947 * More STL & Compiler compatibility fixes.
948 * Changes to use a Point3 class.
949 * Fixed win95/98 time problem that limited fps to about 18.3
952 * Implimented audio envelopes so that pitch of engine changes with throttle
953 * Textured moon, and rewritten/restructured Astro code.
954 * More optimizations and code cleanups. (Norman Vine, Bernie Bright, Charlie
956 * Bug fixed that was causing odd display artifacts due to a degenerate
957 fragment being created for every tile.
958 * Bug fixed that caused scenery generation to go bad (misplaced fclose on an
959 invalid file descriptor.)
960 * Code changes to support g++ 2.7 STL (from Bernie Bright)
963 * Some initial "GameGLUT" support contributed by Gary R. Van Sickle
964 (tiberius@braemarinc.com)
965 * Tracked down and eliminated some memory access type bugs that were
966 causing segfaults on some platforms, with some compilers using various
968 * Assorted code optimizations submitted by Norman Vine.
971 - Created a new directory Simulator/Airports/ to handle airport data
973 - Created Simulator/Object/ to handle basic rendering objects
974 * Panel code update from Friedemann Reinhard (use --enable-panel to activate)
975 * Contributions from Bernie Bright
976 - Created some new classes to enable pointers-to-functions and
977 pointers-to-class-methods to be treated like objects. These objects
978 can be registered with fgEVENT_MGR.
979 - File "Include/fg_callback.hxx" contains the callback class defns.
980 - Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
981 some minor tweaks to STL usage.
982 - Added file "Include/fg_stl_config.h" to deal with STL portability
983 issues. Added an initial config for egcs (and probably gcc-2.8.x).
984 Don't have access to Visual C++ so I've left that for someone else.
985 - This file is influenced by the stl_config.h file delivered with egcs.
986 - Added "Include/auto_ptr.hxx" which contains an implementation of the
987 STL auto_ptr class which is not provided in all STL implementations
988 and is needed to use the callback classes.
989 - Deleted fgLightUpdate() which was just a wrapper to call
991 - Modified fg_init.cxx to register two method callbacks in place of the
992 old wrapper functions.
993 - The new classes in libmisc.tgz define a stream interface into zlib.
994 I've put these in a new directory, Lib/Misc. Feel free to rename it
995 to something more appropriate. However you'll have to change the
996 include directives in all the other files. Additionally you'll have
997 add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
999 The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
1000 test so I've included the required changes in config.tgz.
1002 There are a fair few changes to Simulator/Objects as I've moved
1003 things around. Loading tiles is quicker but thats not where the delay
1004 is. Tile loading takes a few tenths of a second per file on a P200
1005 but it seems to be the post-processing that leads to a noticeable
1006 blip in framerate. I suppose its time to start profiling to see where
1009 I've included a brief description of each archives contents.
1014 C++ stream interface into zlib.
1015 Taken from zlib-1.1.3/contrib/iostream/.
1016 Minor mods for STL compatibility.
1017 There's no copyright associated with these so I assume they're
1022 FlightGear input stream using gz_ifstream. Tries to open the
1023 given filename. If that fails then filename is examined and a
1024 ".gz" suffix is removed or appended and that file is opened.
1027 A simple timer for benchmarking. Not used in production code.
1028 Taken from the Blitz++ project. Covered by GPL.
1032 Some simple string manipulation routines.
1035 Load airports database using fgstream.
1036 Changed fgAIRPORTS to use set<> instead of map<>.
1037 Added bool fgAIRPORTS::search() as a neater way doing the lookup.
1038 Returns true if found.
1041 Modified fgStarsInit() to load stars database using fgstream.
1044 Modified fgObjLoad() to use fgstream.
1045 Modified fgMATERIAL_MGR::load_lib() to use fgstream.
1046 Many changes to fgMATERIAL.
1047 Some changes to fgFRAGMENT but I forget what!
1050 * Stars added in 8 stages as sky gets darker for a smoother more realistic
1052 * rewrote star loader to significantly improve load times.
1053 * Tweaked sky brightness and dawn/dusk colors.
1054 * Fixed a small problem with moon rendering.
1055 * Fog color tries to track the sky color at the center of view in sunrise
1056 and sunset situations.
1057 * Optimizations from Norman Vine
1058 * Code fixes and tweaks from Charlie Hotchkiss.
1059 * Added an --enable/disable-sound option.
1060 * Added a pause key "p"
1061 * Added command line options to specify initial position and orientation.
1062 * Added command line option to start in paused or unpaused state.
1066 * Various HUD intensities so you can find something that is readable for the
1067 current conditions and lighting.
1068 * Tie visibility to far clip plane & view frustum culling so reducting
1069 visibility can increase frame rates by increasing what is culled.
1070 * Fixed stupid bug with misplaced initial position.
1071 * Hopefully fixed a bug when parsing system.fgfsrc on windoze.
1074 * HUD updates from Charlie Hotchkiss (ladder number rotate w/ ladder, control
1075 position indicators are back)
1076 * Only draw the PUI cursor if Mesa/Glide/Fullscreen.
1078 * Calculate the model view transformation matrix once per tile per iteration.
1079 Then glLoadMatrixd() it for each fragment rather than calling push(),
1081 * Added a basic splash screen.
1082 * Added support for switching between fullscreen and window mode for
1084 * added an enable/disable splash screen option
1085 * added an enable/disable intro music option
1086 * added an enable/disable instrument panel option
1087 * added an enable/disable mouse pointer option
1088 * Ground collision detection. You can now land or test for collision with
1089 any scenery surface.
1090 * Converted angle of attack scale into a radio altimeter.
1093 * Managment of multiple textures
1094 * Incorporated Friedemann Reinhard's initial panel code.
1095 * Fog mode is now GL_FOG_EXP2 instead of GL_FOG_LINEAR
1096 * Build the non-shared pieces of the FG sim as static libs.
1099 * Incorporated Steve Baker's PUI user interface library written
1100 entirely on top of OpenGL
1101 * Incorporated Steve Baker's Audio library which currently only
1102 supports Linux, but a win32 port is very close to being done.
1103 * Sort object fragments by material property before rendering. This
1104 will be a big help to performance when we start including objects
1105 with a wide variety of material properties and textures.
1106 * Overlapped scenery tiles to reduce the chance of an occasional
1107 floating point precission induced gaps.
1108 * Fixed a bug in zlib exposed by Borland Win32 compiler.
1109 * Impose a maximum triangle area during scenery generation so even
1110 very flat areas will get split into a few smaller sub triangles.
1111 * Fine grained (fragment level) view frustum culling.
1112 * view transformation optimizations -- Norman Vine.
1113 * Fixed polygon winding problem in scenery generation, so all
1114 tri-strips are wound counter clockwise (opengl default).
1117 * Course (per tile) view frustum culling.
1118 * Added a command line option to specify --fg-root which will override
1120 * Hard coded default locations for FG_ROOT for situations when nothing
1121 is specified. Unix = /usr/local/lib/FlightGear Win32 = \FlightGear
1122 * Restructured the command line processing code so that it can process
1123 these sames comands (one per line) out of a config file.
1124 * Added a command line option to specify field of view. This is
1125 adjustable at run time using "X / x". Supporting code contributed
1129 * Complete C++ re-write of the HUD section.
1130 * Miscellaneous bug fixes and tweaks.
1133 * Added an option to enable/disable wireframe rendering.
1134 * Added an option to enable/disable fog/haze.
1135 * Added an option to enable/disable sky blending.
1136 * Added an option to select smooth/flat polygon shading.
1137 * Added an option to enable full-screen mode.
1138 * Added a visual frame rate counter on the HUD. (Contributed by Durk Talsma)
1139 * Autopilot updates (Jeff Goeke-Smith)
1140 * Added an option to control the number of neighboring tiles that are drawn
1143 * Fixed a horible bug that cause the time to be *WAY* off when
1144 compiling with the CygWin32 compiler.
1145 * Wrap up zlib so we can conditionally compile back in normal behavior
1146 on systems that have trouble building zlib.
1147 * Minor adjustment to texture coordinate generation to reduce texture
1149 * Added a command line option to enable/disable texture maps
1150 * Minor transformation adjustments to try to keep scenery tiles closer
1151 to (0, 0, 0) GLfloats run out of precision at the distances we need
1152 to model the earth, but we can do a bunch of pre-transformations
1153 using double floats and then cast to GLfloat once everything is
1154 close in where we have less precision problems.
1155 * command line option to set starting position by airport ID
1156 * Cleaned up initialization sequence to eliminate interdependencies
1157 between sun position, lighting, and view position. This creates a
1158 valid single pass initialization path.
1159 * use already calculated LaRCsim values to create the roll/pitch/yaw
1160 transformation matrix
1163 * material properties bug fixed when rendering terrain.
1164 * bug in sky color generation fixed.
1165 * bug in fog color generation fixed.
1166 * zlib on the fly decompression/compression support.
1167 * more code reorganization and clean ups.
1168 * a fixed up 30 arcsec DEM file preprocessor. World wide DEM's are
1169 available in this format.
1172 * Simple autopilot heading hold contributed by
1173 Jeff Goeke-Smith <jgoeke@voyager.net>
1174 * More code reorganization and clean ups.
1177 * Many autoconf cleanups and tweaks
1178 * make and make install work in unix
1179 * make works for cygnus win32 (but not install yet)
1180 * make dist now works
1181 * added the Tools directory into the main source tree
1184 * Gnu automake/autoconf/libtool make system
1185 * Initial texture support
