649 from the instrument panel.
650 * Fixed a bug when loading the "old" binary scenery which prevented ground
651 lighting from being generated.
652 * Jettison old conditionally compiled plib-1.2.x code, we now require

678 * Converted from hardcoded to configurable keyboard bindings.
679 * Added an FGSubsystem base class so subsystems can be managed with a
681 * Keyboard commands are now completely remapable. Removed BFI and
682 keyboard in place of remapable inputs.
683 * Started to impliment a command manager. This along with the
684 property manager will go a long ways toward building infrastructure

702 program. (Output radio stack settings so current VOR and OBS can be
704 * Autopilot made to work more like a real world autopilot (rather than
705 based on perfect values.) Autopilot wing leveler is slaved off the
706 turn coordinator. Heading hold is slaved from the DG (which drifts).
707 Nav and ILS holds slave off the needle position.
708 * Backcorse ILS needle should move in correct direction now.
709 * Identing of NAV radios (and individual volume control) now work.

743 * Fixes and improvements to the save/restore code.
744 * Added a load/save dialog box for saving/restoring your current flight.

748 * Added a visibility= command line option for setting intial visibility
750 * Range of tiles loaded and drawn are now directly calculated from the current
751 visibility distance so that the ground always blends smoothly into sky.

811 * Complete reengineering of the panel code in preparation for moving the
812 configuration out into a data file.
813 * Lots of hashing around with Joystick support trying to achieve something
814 that is flexible enough to handle the zillions of possible configurations
815 out there. Hopefully we are approaching a workable solution.
816 * Better windows support in our joystick module.
817 * View code simplifications and optimizations contributed by Norman Vine.
819 * Added support for $FG_SCENERY and --fg-scenery=path so scenery can have a

843 remote joystick connected to another machine. This is in support of
844 some custom hardware located in the human factors research lab of the
845 university of minnesota.
846 * HUD controls are a bit different "h" toggles through day/night/off
847 modes and "H" cycles through brightness levels.
848 * Norman Vine contributed code to optionally do antialiased hud lines
849 on hardware that supports this. Norman also contributed additional
850 hud cleanups and updates.
851 * Updates to JSBsim flight dynamics code that includes a generic
852 reconfigurable flight control system, a initial state trimming routine,
853 support for wind and weather, support for flaps, independent trim control,
855 * Updates to LaRCsim flight dynamcis code contributed by UIUC that
856 allows loading aircraft specifications at runtime from config files.
857 UIUC is using flightgear as a platform to do icing research. The UIUC
858 aircraft use the c172 gear model for now which causes some weirdness
859 on the ground for some of the larger aircraft.
860 * Flight model no longer has to be chosen at compile time.
861 * Separated ephemeris code from the actual sky rendering code and gave
862 this whole section a big overhaul. The moon should now consistantly
863 have the correct phase.
864 * Rebuilt the sky dome using ssg.
865 * Removed dependencies on mat3.h and friends (old srgp support lib)
866 * Airport lookups now done through gdbm (a light weight embedded database.)
867 * Converted ssgVTable's to ssgVtxTables which do proper memory
868 management and should facilitate use of compiled vertex arrays once
869 ssg add support for these.
870 * Overhauled autopilot internals, separated out the gui controls from
871 the actual autopilot code.
872 * Cygwin32 build fixes
878 * Lots of code reorganizations
879 * Build requires plib-1.1.x
880 * Build requires SimGear-0.0.x
881 * LaRCsim/c172 is now the default aircraft model.
882 * Added flaps support to control model.
883 * Lots of updates and tweaks for the LaRCsim/c172 model.
884 * Use a more standard texture/blend mode combination for sun/moon halos to
885 avoid render path that's not supported by all cards/drivers.
886 * Change reported speed on hud from V_equiv_kts to V_calibrated_kts
887 * Instrument panel rewrite by David Megginson. This isn't quite as flashy
888 as the first pass, but is much more functional, plays much better with
889 opengl, and it should be relatively easy for someone with graphical skills
890 to make it look more spiffy.
891 * MacOS fixes contributed by Darrell Walisser.
892 * Many JSBsim updates.
893 * Added a screen snapshot facility (F3).
894 * Added a load/save state function contributed by David Megginson.
895 * Added support for various I/O protocols and channels so that flightgear
896 can communicate with itself and other programs through a variety of means.
897 * Bug fix: The aircraft model used for external views was being included in
898 the height above terrain check so when the view position and the aircraft
899 model collided the current altitude kept getting pushed up to compensate,
900 but of course the aircraft model would get pushed up as well because it
901 tracks the current aircraft position and orientation. Thus you had a never
903 * Oliver's multiplayer network code now moved to his own subdirectory:
905 * Added simulated cloud puffs as we pass through the cloud layer.
906 * Cleaned up some memory leaks occuring between ssg and flightgear.
907 * Update to Christian's weather data base code.
910 * Durk Talsma added a nifty cloud layer.

912 * Added routines to do screen printing contributed by Mark Vallevand.
913 * Added routines to do screen shots to ppm graphics file (all platforms)
914 contributed Rich Kaszeta.
915 * Added a magic carpet (aka slew) mode.
916 * Added a hot air balloon simulator mode. (alpha)
917 * Added a simple (direct lincage) autocoordation feature.
918 * Added a mode to control view (side to side and up and down) with the mouse.
919 * Fixed a DEM decoding problem which caused most of the terrain to be 256
920 meter too high (and regenerated the world scenery with proper elevations.)
922 * Added support for a pilot view offset from the center of gravity.
923 * Various platform portability fixes.
924 * Updated time-offset/syncing command line options.
925 * Updated the FDM <==> Flight Gear interface to be more object oriented.
926 This should hopefully pave the way for being able to simulate several
928 * Removed unimplemented menu entries.
929 * Various scenery tools changes and enhancements in preparation for adding
930 runways (hopefully for the next release.)
933 * Autopilot can now fly great circle routes.
934 * Incorporated a first stab at some networking code contributed by Oliver

938 * Added a flight model acceleration funtion.
939 * Added support for mouse yoke control contributed by David Megginson.
940 * FDM model hertz now definable from the command line.
941 * Added initial timezone support so the user can have better control and more
942 options for setting the starting time of the sim.
943 * We now draw nonexistant tiles as ocean which means we only have to create
944 and distribute tiles that contain some sort of land mass.
946 * Replaced basic render engine with plib's ssg (simple scene graph).
947 * Now expect plib to be installed in it's one true and official location.
948 * Added support for timegm() if it exists which explicitely expects GMT input.
949 * A bit of your basic code reorganization and shuffling.
951 * Removed tools dependency on libgfc. Functionality is now covered by
952 shapelib which has been added into the Tools tree.
953 * Added support for the wonderful GSHHS global land mass data set.
954 * Removed dependecy on process-dem.pl script.
955 * Created a new distributed/parallel tile build system ... hmmm kind of super
956 computer or beowulf style stuff for getting large chunks of scenery built
958 * Only generate tiles that have land mass data since the sim can recreate pure
959 ocean tiles on the fly.
960 * First stab at a water flattening scheme to prevent oceans, lakes, and rivers
961 from running up and down the sides of hills.
962 * Changed the default "Work/" subdirectory layout.

978 fixed, distorted textures have been fixed, real coastlines have been added,
979 and many other subtle improvements.
980 * Tools for parallelizing the scenery building tasks. For instance by using
981 20 machines in parallel, scenery for the entire USA can be regenerated in
982 just over 4 hours vs. 70+ hours on a single machine.
983 * Texture scale can be specified (and changed)( in the materials file. The
984 sim must be rerun for the change to take effect.
985 * Windows now uses plib joystick code so rudder pedals should now work.
986 * Now builds against Steve Baker's plib (portable game devel library)
987 distributed separately (www.woodsoup.org/~sbaker/plib/)
988 * Many source code changes for the MacOS port contributed by Darrell
989 Walisser (the port isn't quite there yet ...)
990 * Source code changes for better compiling with the Borland compiler.
991 * Source code changes for better compiling with the native Irix compilers.
992 * Fixed a bug so you can now fly across the international date line (or

1003 * Added serial output support for an "in-development" full motion cockpit.
1004 * "Just in time" texture loading to reduce initial sim loading time.
1007 New in 0.59 (This is an intermediate/stepping stone release. Skip this
1008 release if you are interested in stability.)
1009 * IRIX portability changes and support for native SGI compilers.
1010 * Solaris portability tweaks
1011 * Incorporated some MacOS portability changes (although the port is not
1013 * Changes to allow adjustment of the autopilot settings while it is
1015 * Began complete overhaul of scenery generation tools.
1016 * Fixed a view frustum culling bug.
1017 * separated lib GPC (generic polygon clipper.) GPC is not "freeware" and
1018 the author has explicitely refused our request to distribute source code
1019 for this library with Flight Gear.
1020 * updated installation and getting started guide
1021 * switched to a simpler, lighter weight frame rate calculation method.
1022 * new tile division scheme.
1023 * GPS serial *output* fixes.
1024 * Added a nifty halo to both the sun and moon. Preparation for allowing
1025 subtle moon lighting effects at night.
1026 * Incorporated Jon Berndt's new C++ flight model rewrite.
1027 * Autopilot settings can be adjusted while active.
1028 * Updates to the instrument panel.

1038 Still lots to do, but you can watch a balistic flight for a short time.
1039 * Renamed Simulator/Flight to Simulator/FDM
1040 * Tweaks to assist building FGFS on solaris platforms.
1041 * Moved Lib/DEM to Tools/DEM
1042 * Started preparations for scenery generation tools overhaul.
1043 * More MSVC++ support.
1044 * Removed code that made the sun bigger at the horizon since this is just
1045 an optical illusion in real life.
1046 * Bug fixed so that the sim can start out at an airport below sea level.
1049 * Converted to a simpler frame rate counting method.
1050 * Fixed the AOA reading on the HUD.
1051 * Removed gpc from the Lib section of distribution by request of the
1052 gpc Author. The gpc license is unfortunately not compatible with
1053 the GPL. I may look for an alternative library, or just require
1054 that developers download this library separately.
1055 * First slew of changes from the MacOS porting effort contributed by
1056 "Robert Puyol" <puyol@abvent.fr>.

1064 external input (serial port, network, file, etc.)
1065 * Fixed a problem that creeped in with setting the initial startup altitude.
1066 This could cause an unrecoverable bounce and you'd end up flipped on your
1067 back. Should be fixed now.
1068 * Sun now appears to grow in size as it gets very low in the horizon.
1069 * Fixed a view frustum culling bug where the scene was not accurately culled
1070 when your view was anything other than straight forward.
1073 * Changed default HUD units to the more standard feet units. You can still
1074 use meters by specifying the command line option "--units-meters".
1075 * Added some initial joystick support using Steve's joystick interface class.
1076 This works great under Linux, but Steve's class now needs to be ported to
1077 Windoze and other platforms.
1078 * Also added a fall back to the GLUT joystick routines for windows (until
1079 we can find better joystick support.)
1080 * Added some initial serial port support for acting like gps and outputing
1081 nmea data such that could be fed into a flight map software package.
1082 * Miscellaneous code clean ups, portability improvements, and optimizations.
1083 * Switched to a streams based error/debug logging system that can be

1091 http://www.cs.man.ac.uk/aig/staff/alan/software/
1092 * Brakes (use "b" to toggle)
1093 * Added an altitude hold module to the autopilot. Lock your current altitude
1094 with "ctrl-a", "cntr-a" again will deactivate. (Also lock your current
1095 heading with "ctrl-h", and again to deactivate.)
1096 * Added a terrain following module ... "ctrl-t" to activate.
1097 * Added an autothrottle ... "ctrl-s" to activate.
1098 * Fixes so that terrain tools will work in windoze.
1099 * More STL & Compiler compatibility fixes.
1100 * Changes to use a Point3 class.
1101 * Fixed win95/98 time problem that limited fps to about 18.3
1104 * Implimented audio envelopes so that pitch of engine changes with throttle
1105 * Textured moon, and rewritten/restructured Astro code.
1106 * More optimizations and code cleanups. (Norman Vine, Bernie Bright, Charlie
1108 * Bug fixed that was causing odd display artifacts due to a degenerate
1109 fragment being created for every tile.
1110 * Bug fixed that caused scenery generation to go bad (misplaced fclose on an
1111 invalid file descriptor.)

1118 causing segfaults on some platforms, with some compilers using various
1120 * Assorted code optimizations submitted by Norman Vine.
1121 * Renamed fg -> fgfs
1123 - Created a new directory Simulator/Airports/ to handle airport data
1125 - Created Simulator/Object/ to handle basic rendering objects
1126 * Panel code update from Friedemann Reinhard (use --enable-panel to activate)
1127 * Contributions from Bernie Bright
1128 - Created some new classes to enable pointers-to-functions and
1129 pointers-to-class-methods to be treated like objects. These objects
1130 can be registered with fgEVENT_MGR.
1131 - File "Include/fg_callback.hxx" contains the callback class defns.
1132 - Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
1133 some minor tweaks to STL usage.
1134 - Added file "Include/fg_stl_config.h" to deal with STL portability
1135 issues. Added an initial config for egcs (and probably gcc-2.8.x).
1136 Don't have access to Visual C++ so I've left that for someone else.
1137 - This file is influenced by the stl_config.h file delivered with egcs.
1138 - Added "Include/auto_ptr.hxx" which contains an implementation of the
1139 STL auto_ptr class which is not provided in all STL implementations
1140 and is needed to use the callback classes.
1141 - Deleted fgLightUpdate() which was just a wrapper to call
1143 - Modified fg_init.cxx to register two method callbacks in place of the
1144 old wrapper functions.
1145 - The new classes in libmisc.tgz define a stream interface into zlib.
1146 I've put these in a new directory, Lib/Misc. Feel free to rename it
1147 to something more appropriate. However you'll have to change the
1148 include directives in all the other files. Additionally you'll have
1149 add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
1151 The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
1152 test so I've included the required changes in config.tgz.
1154 There are a fair few changes to Simulator/Objects as I've moved
1155 things around. Loading tiles is quicker but thats not where the delay
1156 is. Tile loading takes a few tenths of a second per file on a P200
1157 but it seems to be the post-processing that leads to a noticeable
1158 blip in framerate. I suppose its time to start profiling to see where
1161 I've included a brief description of each archives contents.
1166 C++ stream interface into zlib.
1167 Taken from zlib-1.1.3/contrib/iostream/.
1168 Minor mods for STL compatibility.
1169 There's no copyright associated with these so I assume they're
1174 FlightGear input stream using gz_ifstream. Tries to open the
1175 given filename. If that fails then filename is examined and a
1176 ".gz" suffix is removed or appended and that file is opened.
1179 A simple timer for benchmarking. Not used in production code.
1180 Taken from the Blitz++ project. Covered by GPL.
1184 Some simple string manipulation routines.
1187 Load airports database using fgstream.
1188 Changed fgAIRPORTS to use set<> instead of map<>.
1189 Added bool fgAIRPORTS::search() as a neater way doing the lookup.
1190 Returns true if found.
1193 Modified fgStarsInit() to load stars database using fgstream.
1196 Modified fgObjLoad() to use fgstream.
1197 Modified fgMATERIAL_MGR::load_lib() to use fgstream.
1198 Many changes to fgMATERIAL.
1199 Some changes to fgFRAGMENT but I forget what!
1202 * Stars added in 8 stages as sky gets darker for a smoother more realistic
1204 * rewrote star loader to significantly improve load times.
1205 * Tweaked sky brightness and dawn/dusk colors.
1206 * Fixed a small problem with moon rendering.
1207 * Fog color tries to track the sky color at the center of view in sunrise
1208 and sunset situations.
1209 * Optimizations from Norman Vine
1210 * Code fixes and tweaks from Charlie Hotchkiss.
1211 * Added an --enable/disable-sound option.
1212 * Added a pause key "p"
1213 * Added command line options to specify initial position and orientation.
1214 * Added command line option to start in paused or unpaused state.
1218 * Various HUD intensities so you can find something that is readable for the
1219 current conditions and lighting.
1220 * Tie visibility to far clip plane & view frustum culling so reducting
1221 visibility can increase frame rates by increasing what is culled.
1222 * Fixed stupid bug with misplaced initial position.
1223 * Hopefully fixed a bug when parsing system.fgfsrc on windoze.
1226 * HUD updates from Charlie Hotchkiss (ladder number rotate w/ ladder, control
1227 position indicators are back)
1228 * Only draw the PUI cursor if Mesa/Glide/Fullscreen.
1230 * Calculate the model view transformation matrix once per tile per iteration.
1231 Then glLoadMatrixd() it for each fragment rather than calling push(),
1233 * Added a basic splash screen.
1234 * Added support for switching between fullscreen and window mode for
1236 * added an enable/disable splash screen option
1237 * added an enable/disable intro music option
1238 * added an enable/disable instrument panel option
1239 * added an enable/disable mouse pointer option
1240 * Ground collision detection. You can now land or test for collision with
1241 any scenery surface.
1242 * Converted angle of attack scale into a radio altimeter.
1245 * Managment of multiple textures
1246 * Incorporated Friedemann Reinhard's initial panel code.
1247 * Fog mode is now GL_FOG_EXP2 instead of GL_FOG_LINEAR
1248 * Build the non-shared pieces of the FG sim as static libs.
1251 * Incorporated Steve Baker's PUI user interface library written
1252 entirely on top of OpenGL
1253 * Incorporated Steve Baker's Audio library which currently only
1254 supports Linux, but a win32 port is very close to being done.
1255 * Sort object fragments by material property before rendering. This
1256 will be a big help to performance when we start including objects
1257 with a wide variety of material properties and textures.
1258 * Overlapped scenery tiles to reduce the chance of an occasional
1259 floating point precission induced gaps.
1260 * Fixed a bug in zlib exposed by Borland Win32 compiler.
1261 * Impose a maximum triangle area during scenery generation so even
1262 very flat areas will get split into a few smaller sub triangles.
1263 * Fine grained (fragment level) view frustum culling.
1264 * view transformation optimizations -- Norman Vine.
1265 * Fixed polygon winding problem in scenery generation, so all
1266 tri-strips are wound counter clockwise (opengl default).
1269 * Course (per tile) view frustum culling.
1270 * Added a command line option to specify --fg-root which will override
1272 * Hard coded default locations for FG_ROOT for situations when nothing
1273 is specified. Unix = /usr/local/lib/FlightGear Win32 = \FlightGear
1274 * Restructured the command line processing code so that it can process
1275 these sames comands (one per line) out of a config file.
1276 * Added a command line option to specify field of view. This is
1277 adjustable at run time using "X / x". Supporting code contributed
1281 * Complete C++ re-write of the HUD section.
1282 * Miscellaneous bug fixes and tweaks.
1285 * Added an option to enable/disable wireframe rendering.
1286 * Added an option to enable/disable fog/haze.
1287 * Added an option to enable/disable sky blending.
1288 * Added an option to select smooth/flat polygon shading.
1289 * Added an option to enable full-screen mode.
1290 * Added a visual frame rate counter on the HUD. (Contributed by Durk Talsma)
1291 * Autopilot updates (Jeff Goeke-Smith)
1292 * Added an option to control the number of neighboring tiles that are drawn
1295 * Fixed a horible bug that cause the time to be *WAY* off when
1296 compiling with the CygWin32 compiler.
1297 * Wrap up zlib so we can conditionally compile back in normal behavior
1298 on systems that have trouble building zlib.
1299 * Minor adjustment to texture coordinate generation to reduce texture
1301 * Added a command line option to enable/disable texture maps
1302 * Minor transformation adjustments to try to keep scenery tiles closer
1303 to (0, 0, 0) GLfloats run out of precision at the distances we need
1304 to model the earth, but we can do a bunch of pre-transformations
1305 using double floats and then cast to GLfloat once everything is
1306 close in where we have less precision problems.
1307 * command line option to set starting position by airport ID
1308 * Cleaned up initialization sequence to eliminate interdependencies
1309 between sun position, lighting, and view position. This creates a
1310 valid single pass initialization path.
1311 * use already calculated LaRCsim values to create the roll/pitch/yaw
1312 transformation matrix
1315 * material properties bug fixed when rendering terrain.
1316 * bug in sky color generation fixed.
1317 * bug in fog color generation fixed.
1318 * zlib on the fly decompression/compression support.
1319 * more code reorganization and clean ups.
1320 * a fixed up 30 arcsec DEM file preprocessor. World wide DEM's are
1321 available in this format.
1324 * Simple autopilot heading hold contributed by
1325 Jeff Goeke-Smith <jgoeke@voyager.net>
1326 * More code reorganization and clean ups.
1329 * Many autoconf cleanups and tweaks
1330 * make and make install work in unix
1331 * make works for cygnus win32 (but not install yet)
1332 * make dist now works
1333 * added the Tools directory into the main source tree
1336 * Gnu automake/autoconf/libtool make system
1337 * Initial texture support
