596 * Converted from hardcoded to configurable keyboard bindings.
597 * Added an FGSubsystem base class so subsystems can be managed with a
599 * Keyboard commands are now completely remapable. Removed BFI and
600 keyboard in place of remapable inputs.
601 * Started to impliment a command manager. This along with the
602 property manager will go a long ways toward building infrastructure
604 * Started laying infrastructure for creating ultra-high-res tiled
605 screen shots suitable for printers.
606 * Synced with a recent version of JSBSim.
607 * GUI code split into smaller logical subcomponents.

612 * Support for setting a starting position as and offset distance (and /
613 or radial) from your specified starting postition. This allows you to
614 initialize on final x miles out at y altitude.
615 * Many updates to make a much more realistic single engine and prop model
616 with atmospheric and velocity dependencies. Fuel flow now modeled.
617 * Straightened out magnetic offset issues with VOR stations so we can
618 navigate properly from real avaition charts.
619 * Added a direct network interface support for the "Atlas" moving map
620 program. (Output radio stack settings so current VOR and OBS can be
622 * Autopilot made to work more like a real world autopilot (rather than
623 based on perfect values.) Autopilot wing leveler is slaved off the
624 turn coordinator. Heading hold is slaved from the DG (which drifts).
625 Nav and ILS holds slave off the needle position.
626 * Backcorse ILS needle should move in correct direction now.
627 * Identing of NAV radios (and individual volume control) now work.
628 * Don't play DME ident if no colocated DME.
629 * VOR/ILS/ADF range pickup realistically modeled as per AIM.
630 * Added support for marker beacons.
631 * Support for loading and saving the current 'simulator state' using
632 an xml formated file.
633 * Added threaded tile paging for systems with pthread support.
634 * Added high level support for creating airport taxiway and runway signs.
635 * Many updates and fixes to the "installation and getting started" manual.
636 * Support for adding static objects to the scenery.
637 * Many updates and new features for the xml configurable panel engine.
638 Many corresponding improvements to the default instrument panel.

640 * Added support for a new, smaller, faster binary scenery format.
641 * Added an xml configurable HUD engine.
642 * Added interface glue to propogate wind values to LaRCsim.
646 * Added night ground cover lights with user controllable densities on
647 a per texture basis. Lights have a bit of a "fog punch through" effect.
648 * Support added for "shaped" instrument panels.
649 * Added support for virtual panels that are larger than the screen
650 space which can scroll.
651 * Added waypoint and route flying support to the autopilot and HUD.
652 * New highly detailed runway textures with accurate markings.

655 * Many tweaks and improvements to the c172 instrument panel.
656 * Corrections and additions to the airport and navaid database.
657 * Added an external interface to the property manager so you can
658 "telnet" into a running copy of FlightGear, cd through the property
659 tree and examine and even change values, all from a remote computer.
660 * Improvements to flight model initialization.
661 * Fixes and improvements to the save/restore code.
662 * Added a load/save dialog box for saving/restoring your current flight.
663 * Program notes max texture size for your card/driver so it can load
664 higher resultion textures if they are available and if you can use
666 * Added a visibility= command line option for setting intial visibility
668 * Range of tiles loaded and drawn are now directly calculated from the current
669 visibility distance so that the ground always blends smoothly into sky.
670 * Rewrote the tile caching scheme so it is now more flexible, more dynamic,
671 simpler, and more robust.
672 * Updates to the FDM bus.
673 * Many clean ups with the view code to prepare the way for a greater
674 variety of external views.
675 * MSVC project files now included in the source distribution.
676 * Fixed a view bug that could make the aircraft model appear rotated
678 * Fixed a bug with the autopilot rate of climb hold.
679 * Internal property manager tweaks.
680 * Additional materials can be aliased to an existing material to save
681 texture space (at the expense of less texture variety)
687 * Aircraft now starts at end of runway closest to desired heading.
688 * Runways now have accurate markings.
689 * Addition of a completely reconfigurable instrument panel.
690 * Tons of panel tweaks and fixes. Gyro now drifts, relocated whisky compass,
691 skid ball moves in the right direction, etc.

724 * Some additional MSVC5 portability fixes.
725 * Tweaks to build with newest gcc under Irix contributed by Erik Hofman.
727 * Clean out a pile of old junk in the material manager library from the
728 pre-ssg days, and majorly overhauled it.
729 * Complete reengineering of the panel code in preparation for moving the
730 configuration out into a data file.
731 * Lots of hashing around with Joystick support trying to achieve something
732 that is flexible enough to handle the zillions of possible configurations
733 out there. Hopefully we are approaching a workable solution.
734 * Better windows support in our joystick module.
735 * View code simplifications and optimizations contributed by Norman Vine.
737 * Added support for $FG_SCENERY and --fg-scenery=path so scenery can have a
738 different location from the base package.
739 * Moved drop in sky module, world time module, ephemeris module, and low
740 level communications modules over to simgear.
741 * Replaced gdbm with metakit
742 * Added David Megginson's property manager
747 * Added a radio stack 2 VOR/ILS and an ADF to the instrument panel.

757 * Added magvar offset to VOR radials.
758 * Heading bug now display magnetic heading rather than true heading.
759 * Autopilot now has modes to track a VOR and GS.
760 * Added custom joystick client support so sim can be flown from a
761 remote joystick connected to another machine. This is in support of
762 some custom hardware located in the human factors research lab of the
763 university of minnesota.
764 * HUD controls are a bit different "h" toggles through day/night/off
765 modes and "H" cycles through brightness levels.
766 * Norman Vine contributed code to optionally do antialiased hud lines
767 on hardware that supports this. Norman also contributed additional
768 hud cleanups and updates.
769 * Updates to JSBsim flight dynamics code that includes a generic
770 reconfigurable flight control system, a initial state trimming routine,
771 support for wind and weather, support for flaps, independent trim control,
773 * Updates to LaRCsim flight dynamcis code contributed by UIUC that
774 allows loading aircraft specifications at runtime from config files.
775 UIUC is using flightgear as a platform to do icing research. The UIUC
776 aircraft use the c172 gear model for now which causes some weirdness
777 on the ground for some of the larger aircraft.
778 * Flight model no longer has to be chosen at compile time.
779 * Separated ephemeris code from the actual sky rendering code and gave
780 this whole section a big overhaul. The moon should now consistantly
781 have the correct phase.
782 * Rebuilt the sky dome using ssg.
783 * Removed dependencies on mat3.h and friends (old srgp support lib)
784 * Airport lookups now done through gdbm (a light weight embedded database.)
785 * Converted ssgVTable's to ssgVtxTables which do proper memory
786 management and should facilitate use of compiled vertex arrays once
787 ssg add support for these.
788 * Overhauled autopilot internals, separated out the gui controls from
789 the actual autopilot code.
790 * Cygwin32 build fixes
796 * Lots of code reorganizations
797 * Build requires plib-1.1.x
798 * Build requires SimGear-0.0.x
799 * LaRCsim/c172 is now the default aircraft model.
800 * Added flaps support to control model.
801 * Lots of updates and tweaks for the LaRCsim/c172 model.
802 * Use a more standard texture/blend mode combination for sun/moon halos to
803 avoid render path that's not supported by all cards/drivers.
804 * Change reported speed on hud from V_equiv_kts to V_calibrated_kts
805 * Instrument panel rewrite by David Megginson. This isn't quite as flashy
806 as the first pass, but is much more functional, plays much better with
807 opengl, and it should be relatively easy for someone with graphical skills
808 to make it look more spiffy.
809 * MacOS fixes contributed by Darrell Walisser.
810 * Many JSBsim updates.
811 * Added a screen snapshot facility (F3).
812 * Added a load/save state function contributed by David Megginson.
813 * Added support for various I/O protocols and channels so that flightgear
814 can communicate with itself and other programs through a variety of means.
815 * Bug fix: The aircraft model used for external views was being included in
816 the height above terrain check so when the view position and the aircraft
817 model collided the current altitude kept getting pushed up to compensate,
818 but of course the aircraft model would get pushed up as well because it
819 tracks the current aircraft position and orientation. Thus you had a never
821 * Oliver's multiplayer network code now moved to his own subdirectory:
823 * Added simulated cloud puffs as we pass through the cloud layer.
824 * Cleaned up some memory leaks occuring between ssg and flightgear.
825 * Update to Christian's weather data base code.
828 * Durk Talsma added a nifty cloud layer.
829 * Default to Christian Mayer's new weather system.
830 * Added routines to do screen printing contributed by Mark Vallevand.
831 * Added routines to do screen shots to ppm graphics file (all platforms)
832 contributed Rich Kaszeta.
833 * Added a magic carpet (aka slew) mode.
834 * Added a hot air balloon simulator mode. (alpha)
835 * Added a simple (direct lincage) autocoordation feature.
836 * Added a mode to control view (side to side and up and down) with the mouse.
837 * Fixed a DEM decoding problem which caused most of the terrain to be 256
838 meter too high (and regenerated the world scenery with proper elevations.)
840 * Added support for a pilot view offset from the center of gravity.
841 * Various platform portability fixes.
842 * Updated time-offset/syncing command line options.
843 * Updated the FDM <==> Flight Gear interface to be more object oriented.
844 This should hopefully pave the way for being able to simulate several
846 * Removed unimplemented menu entries.
847 * Various scenery tools changes and enhancements in preparation for adding
848 runways (hopefully for the next release.)
851 * Autopilot can now fly great circle routes.
852 * Incorporated a first stab at some networking code contributed by Oliver
854 * Added Christian Mayer's new weather subsystem.
855 * Started adding support for "external" views ... still needs some work.
856 * Added a flight model acceleration funtion.
857 * Added support for mouse yoke control contributed by David Megginson.
858 * FDM model hertz now definable from the command line.
859 * Added initial timezone support so the user can have better control and more
860 options for setting the starting time of the sim.
861 * We now draw nonexistant tiles as ocean which means we only have to create
862 and distribute tiles that contain some sort of land mass.
864 * Replaced basic render engine with plib's ssg (simple scene graph).
865 * Now expect plib to be installed in it's one true and official location.
866 * Added support for timegm() if it exists which explicitely expects GMT input.
867 * A bit of your basic code reorganization and shuffling.
869 * Removed tools dependency on libgfc. Functionality is now covered by
870 shapelib which has been added into the Tools tree.
871 * Added support for the wonderful GSHHS global land mass data set.
872 * Removed dependecy on process-dem.pl script.
873 * Created a new distributed/parallel tile build system ... hmmm kind of super
874 computer or beowulf style stuff for getting large chunks of scenery built
876 * Only generate tiles that have land mass data since the sim can recreate pure
877 ocean tiles on the fly.
878 * First stab at a water flattening scheme to prevent oceans, lakes, and rivers
879 from running up and down the sides of hills.
880 * Changed the default "Work/" subdirectory layout.
881 * Updates to better handle segment boundaries in preparation for real airport
882 runway and lighting modeling.
883 * Updates and enhancements to my polygon management class.
886 * Updates to Tony's c172 model.
887 * Updated getting started guide from Micheal Basler.
889 * FreeBSD portability tweaks.
890 * MACos portability tweaks.
891 * Borland C++ tweaks.
895 * Tons of improvements with scenery creation. Inter-tile gaps have been
896 fixed, distorted textures have been fixed, real coastlines have been added,
897 and many other subtle improvements.
898 * Tools for parallelizing the scenery building tasks. For instance by using
899 20 machines in parallel, scenery for the entire USA can be regenerated in
900 just over 4 hours vs. 70+ hours on a single machine.
901 * Texture scale can be specified (and changed)( in the materials file. The
902 sim must be rerun for the change to take effect.
903 * Windows now uses plib joystick code so rudder pedals should now work.
904 * Now builds against Steve Baker's plib (portable game devel library)
905 distributed separately (www.woodsoup.org/~sbaker/plib/)
906 * Many source code changes for the MacOS port contributed by Darrell
907 Walisser (the port isn't quite there yet ...)
908 * Source code changes for better compiling with the Borland compiler.
909 * Source code changes for better compiling with the native Irix compilers.
910 * Fixed a bug so you can now fly across the international date line (or
911 more precisely the division between longitude = +/-180.
912 * Tweaks to the Astro section contributed by Durk Talsma.
913 * Autopilot improvements contributed by Norman Vine.
914 * Fonts/characters now drawn with texture maps for increased speed.
915 * Instrument panel can be toggled on and off with "P".
916 * GUI interface for tweaking some autopilot parameters.

918 faster font drawing for much better performance.
919 * Reset function added to reset you to your starting conditions.
920 * GUI function to enter a new airport id (and be transported there)
921 * Added serial output support for an "in-development" full motion cockpit.
922 * "Just in time" texture loading to reduce initial sim loading time.
925 New in 0.59 (This is an intermediate/stepping stone release. Skip this
926 release if you are interested in stability.)
927 * IRIX portability changes and support for native SGI compilers.
928 * Solaris portability tweaks
929 * Incorporated some MacOS portability changes (although the port is not
931 * Changes to allow adjustment of the autopilot settings while it is
933 * Began complete overhaul of scenery generation tools.
934 * Fixed a view frustum culling bug.
935 * separated lib GPC (generic polygon clipper.) GPC is not "freeware" and
936 the author has explicitely refused our request to distribute source code
937 for this library with Flight Gear.
938 * updated installation and getting started guide
939 * switched to a simpler, lighter weight frame rate calculation method.
940 * new tile division scheme.
941 * GPS serial *output* fixes.
942 * Added a nifty halo to both the sun and moon. Preparation for allowing
943 subtle moon lighting effects at night.
944 * Incorporated Jon Berndt's new C++ flight model rewrite.
945 * Autopilot settings can be adjusted while active.
946 * Updates to the instrument panel.
947 * Fixed AOA reading on the HUD.
948 * Added random splash screens.
949 * Modified scenery loader to accept tri-fans.
950 * Other non-backwards compatible changes to scenery file format and tile
955 * Added JSBsim alpha code ... this is Jon S. Berndts alpha FDM rewrite.
956 Still lots to do, but you can watch a balistic flight for a short time.
957 * Renamed Simulator/Flight to Simulator/FDM
958 * Tweaks to assist building FGFS on solaris platforms.
959 * Moved Lib/DEM to Tools/DEM
960 * Started preparations for scenery generation tools overhaul.
961 * More MSVC++ support.
962 * Removed code that made the sun bigger at the horizon since this is just
963 an optical illusion in real life.
964 * Bug fixed so that the sim can start out at an airport below sea level.
967 * Converted to a simpler frame rate counting method.
968 * Fixed the AOA reading on the HUD.
969 * Removed gpc from the Lib section of distribution by request of the
970 gpc Author. The gpc license is unfortunately not compatible with
971 the GPL. I may look for an alternative library, or just require
972 that developers download this library separately.
973 * First slew of changes from the MacOS porting effort contributed by
974 "Robert Puyol" <puyol@abvent.fr>.
975 * Support for an arbitrary number of serial ports + additional serial port
977 * Serial output tweaks to make things more robust and act more like a GPS.
978 * Portability enhancements for Borland, Solaris, and SGI.
979 * Some internal class renaming and reorganizations. fgFLIGHT becomes FGState.
980 fgCONTROLS becomes FGControls.
981 * Started work on an "external" flight model so the sim can be driven from
982 external input (serial port, network, file, etc.)
983 * Fixed a problem that creeped in with setting the initial startup altitude.
984 This could cause an unrecoverable bounce and you'd end up flipped on your
985 back. Should be fixed now.
986 * Sun now appears to grow in size as it gets very low in the horizon.
987 * Fixed a view frustum culling bug where the scene was not accurately culled
988 when your view was anything other than straight forward.
991 * Changed default HUD units to the more standard feet units. You can still
992 use meters by specifying the command line option "--units-meters".
993 * Added some initial joystick support using Steve's joystick interface class.
994 This works great under Linux, but Steve's class now needs to be ported to
995 Windoze and other platforms.
996 * Also added a fall back to the GLUT joystick routines for windows (until
997 we can find better joystick support.)
998 * Added some initial serial port support for acting like gps and outputing
999 nmea data such that could be fed into a flight map software package.
1000 * Miscellaneous code clean ups, portability improvements, and optimizations.
1001 * Switched to a streams based error/debug logging system that can be
1002 completely stripped out for a release build (./configure --without-logging)
1003 * Support for cygwin32 b20 compiler (latest release)
1004 * Continued progress on instrument panel
1005 * Support for starting fgfs at higher resolutions.

1009 http://www.cs.man.ac.uk/aig/staff/alan/software/
1010 * Brakes (use "b" to toggle)
1011 * Added an altitude hold module to the autopilot. Lock your current altitude
1012 with "ctrl-a", "cntr-a" again will deactivate. (Also lock your current
1013 heading with "ctrl-h", and again to deactivate.)
1014 * Added a terrain following module ... "ctrl-t" to activate.
1015 * Added an autothrottle ... "ctrl-s" to activate.
1016 * Fixes so that terrain tools will work in windoze.
1017 * More STL & Compiler compatibility fixes.
1018 * Changes to use a Point3 class.
1019 * Fixed win95/98 time problem that limited fps to about 18.3
1022 * Implimented audio envelopes so that pitch of engine changes with throttle
1023 * Textured moon, and rewritten/restructured Astro code.
1024 * More optimizations and code cleanups. (Norman Vine, Bernie Bright, Charlie
1026 * Bug fixed that was causing odd display artifacts due to a degenerate
1027 fragment being created for every tile.
1028 * Bug fixed that caused scenery generation to go bad (misplaced fclose on an
1029 invalid file descriptor.)
1030 * Code changes to support g++ 2.7 STL (from Bernie Bright)
1033 * Some initial "GameGLUT" support contributed by Gary R. Van Sickle
1034 (tiberius@braemarinc.com)
1035 * Tracked down and eliminated some memory access type bugs that were
1036 causing segfaults on some platforms, with some compilers using various
1038 * Assorted code optimizations submitted by Norman Vine.
1039 * Renamed fg -> fgfs
1041 - Created a new directory Simulator/Airports/ to handle airport data
1043 - Created Simulator/Object/ to handle basic rendering objects
1044 * Panel code update from Friedemann Reinhard (use --enable-panel to activate)
1045 * Contributions from Bernie Bright
1046 - Created some new classes to enable pointers-to-functions and
1047 pointers-to-class-methods to be treated like objects. These objects
1048 can be registered with fgEVENT_MGR.
1049 - File "Include/fg_callback.hxx" contains the callback class defns.
1050 - Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
1051 some minor tweaks to STL usage.
1052 - Added file "Include/fg_stl_config.h" to deal with STL portability
1053 issues. Added an initial config for egcs (and probably gcc-2.8.x).
1054 Don't have access to Visual C++ so I've left that for someone else.
1055 - This file is influenced by the stl_config.h file delivered with egcs.
1056 - Added "Include/auto_ptr.hxx" which contains an implementation of the
1057 STL auto_ptr class which is not provided in all STL implementations
1058 and is needed to use the callback classes.
1059 - Deleted fgLightUpdate() which was just a wrapper to call
1061 - Modified fg_init.cxx to register two method callbacks in place of the
1062 old wrapper functions.
1063 - The new classes in libmisc.tgz define a stream interface into zlib.
1064 I've put these in a new directory, Lib/Misc. Feel free to rename it
1065 to something more appropriate. However you'll have to change the
1066 include directives in all the other files. Additionally you'll have
1067 add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
1069 The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
1070 test so I've included the required changes in config.tgz.
1072 There are a fair few changes to Simulator/Objects as I've moved
1073 things around. Loading tiles is quicker but thats not where the delay
1074 is. Tile loading takes a few tenths of a second per file on a P200
1075 but it seems to be the post-processing that leads to a noticeable
1076 blip in framerate. I suppose its time to start profiling to see where
1079 I've included a brief description of each archives contents.
1084 C++ stream interface into zlib.
1085 Taken from zlib-1.1.3/contrib/iostream/.
1086 Minor mods for STL compatibility.
1087 There's no copyright associated with these so I assume they're
1092 FlightGear input stream using gz_ifstream. Tries to open the
1093 given filename. If that fails then filename is examined and a
1094 ".gz" suffix is removed or appended and that file is opened.
1097 A simple timer for benchmarking. Not used in production code.
1098 Taken from the Blitz++ project. Covered by GPL.
1102 Some simple string manipulation routines.
1105 Load airports database using fgstream.
1106 Changed fgAIRPORTS to use set<> instead of map<>.
1107 Added bool fgAIRPORTS::search() as a neater way doing the lookup.
1108 Returns true if found.
1111 Modified fgStarsInit() to load stars database using fgstream.
1114 Modified fgObjLoad() to use fgstream.
1115 Modified fgMATERIAL_MGR::load_lib() to use fgstream.
1116 Many changes to fgMATERIAL.
1117 Some changes to fgFRAGMENT but I forget what!
1120 * Stars added in 8 stages as sky gets darker for a smoother more realistic
1122 * rewrote star loader to significantly improve load times.
1123 * Tweaked sky brightness and dawn/dusk colors.
1124 * Fixed a small problem with moon rendering.
1125 * Fog color tries to track the sky color at the center of view in sunrise
1126 and sunset situations.
1127 * Optimizations from Norman Vine
1128 * Code fixes and tweaks from Charlie Hotchkiss.
1129 * Added an --enable/disable-sound option.
1130 * Added a pause key "p"
1131 * Added command line options to specify initial position and orientation.
1132 * Added command line option to start in paused or unpaused state.
1136 * Various HUD intensities so you can find something that is readable for the
1137 current conditions and lighting.
1138 * Tie visibility to far clip plane & view frustum culling so reducting
1139 visibility can increase frame rates by increasing what is culled.
1140 * Fixed stupid bug with misplaced initial position.
1141 * Hopefully fixed a bug when parsing system.fgfsrc on windoze.
1144 * HUD updates from Charlie Hotchkiss (ladder number rotate w/ ladder, control
1145 position indicators are back)
1146 * Only draw the PUI cursor if Mesa/Glide/Fullscreen.
1148 * Calculate the model view transformation matrix once per tile per iteration.
1149 Then glLoadMatrixd() it for each fragment rather than calling push(),
1151 * Added a basic splash screen.
1152 * Added support for switching between fullscreen and window mode for
1154 * added an enable/disable splash screen option
1155 * added an enable/disable intro music option
1156 * added an enable/disable instrument panel option
1157 * added an enable/disable mouse pointer option
1158 * Ground collision detection. You can now land or test for collision with
1159 any scenery surface.
1160 * Converted angle of attack scale into a radio altimeter.
1163 * Managment of multiple textures
1164 * Incorporated Friedemann Reinhard's initial panel code.
1165 * Fog mode is now GL_FOG_EXP2 instead of GL_FOG_LINEAR
1166 * Build the non-shared pieces of the FG sim as static libs.
1169 * Incorporated Steve Baker's PUI user interface library written
1170 entirely on top of OpenGL
1171 * Incorporated Steve Baker's Audio library which currently only
1172 supports Linux, but a win32 port is very close to being done.
1173 * Sort object fragments by material property before rendering. This
1174 will be a big help to performance when we start including objects
1175 with a wide variety of material properties and textures.
1176 * Overlapped scenery tiles to reduce the chance of an occasional
1177 floating point precission induced gaps.
1178 * Fixed a bug in zlib exposed by Borland Win32 compiler.
1179 * Impose a maximum triangle area during scenery generation so even
1180 very flat areas will get split into a few smaller sub triangles.
1181 * Fine grained (fragment level) view frustum culling.
1182 * view transformation optimizations -- Norman Vine.
1183 * Fixed polygon winding problem in scenery generation, so all
1184 tri-strips are wound counter clockwise (opengl default).
1187 * Course (per tile) view frustum culling.
1188 * Added a command line option to specify --fg-root which will override
1190 * Hard coded default locations for FG_ROOT for situations when nothing
1191 is specified. Unix = /usr/local/lib/FlightGear Win32 = \FlightGear
1192 * Restructured the command line processing code so that it can process
1193 these sames comands (one per line) out of a config file.
1194 * Added a command line option to specify field of view. This is
1195 adjustable at run time using "X / x". Supporting code contributed
1199 * Complete C++ re-write of the HUD section.
1200 * Miscellaneous bug fixes and tweaks.
1203 * Added an option to enable/disable wireframe rendering.
1204 * Added an option to enable/disable fog/haze.
1205 * Added an option to enable/disable sky blending.
1206 * Added an option to select smooth/flat polygon shading.
1207 * Added an option to enable full-screen mode.
1208 * Added a visual frame rate counter on the HUD. (Contributed by Durk Talsma)
1209 * Autopilot updates (Jeff Goeke-Smith)
1210 * Added an option to control the number of neighboring tiles that are drawn
1213 * Fixed a horible bug that cause the time to be *WAY* off when
1214 compiling with the CygWin32 compiler.
1215 * Wrap up zlib so we can conditionally compile back in normal behavior
1216 on systems that have trouble building zlib.
1217 * Minor adjustment to texture coordinate generation to reduce texture
1219 * Added a command line option to enable/disable texture maps
1220 * Minor transformation adjustments to try to keep scenery tiles closer
1221 to (0, 0, 0) GLfloats run out of precision at the distances we need
1222 to model the earth, but we can do a bunch of pre-transformations
1223 using double floats and then cast to GLfloat once everything is
1224 close in where we have less precision problems.
1225 * command line option to set starting position by airport ID
1226 * Cleaned up initialization sequence to eliminate interdependencies
1227 between sun position, lighting, and view position. This creates a
1228 valid single pass initialization path.
1229 * use already calculated LaRCsim values to create the roll/pitch/yaw
1230 transformation matrix
1233 * material properties bug fixed when rendering terrain.
1234 * bug in sky color generation fixed.
1235 * bug in fog color generation fixed.
1236 * zlib on the fly decompression/compression support.
1237 * more code reorganization and clean ups.
1238 * a fixed up 30 arcsec DEM file preprocessor. World wide DEM's are
1239 available in this format.
1242 * Simple autopilot heading hold contributed by
1243 Jeff Goeke-Smith <jgoeke@voyager.net>
1244 * More code reorganization and clean ups.
1247 * Many autoconf cleanups and tweaks
1248 * make and make install work in unix
1249 * make works for cygnus win32 (but not install yet)
1250 * make dist now works
1251 * added the Tools directory into the main source tree
1254 * Gnu automake/autoconf/libtool make system
1255 * Initial texture support
