512 on the ground for some of the larger aircraft.
513 * Flight model no longer has to be chosen at compile time.
514 * Separated ephemeris code from the actual sky rendering code and gave

524 the actual autopilot code.
525 * Cygwin32 build fixes
531 * Lots of code reorganizations

538 avoid render path that's not supported by all cards/drivers.
539 * Change reported speed on hud from V_equiv_kts to V_calibrated_kts
540 * Instrument panel rewrite by David Megginson. This isn't quite as flashy
541 as the first pass, but is much more functional, plays much better with
542 opengl, and it should be relatively easy for someone with graphical skills
543 to make it look more spiffy.
544 * MacOS fixes contributed by Darrell Walisser.
545 * Many JSBsim updates.
546 * Added a screen snapshot facility (F3).

548 * Added support for various I/O protocols and channels so that flightgear
549 can communicate with itself and other programs through a variety of means.
550 * Bug fix: The aircraft model used for external views was being included in
551 the height above terrain check so when the view position and the aircraft
552 model collided the current altitude kept getting pushed up to compensate,
553 but of course the aircraft model would get pushed up as well because it
554 tracks the current aircraft position and orientation. Thus you had a never
556 * Oliver's multiplayer network code now moved to his own subdirectory:
558 * Added simulated cloud puffs as we pass through the cloud layer.
559 * Cleaned up some memory leaks occuring between ssg and flightgear.

573 meter too high (and regenerated the world scenery with proper elevations.)
575 * Added support for a pilot view offset from the center of gravity.
576 * Various platform portability fixes.
577 * Updated time-offset/syncing command line options.
578 * Updated the FDM <==> Flight Gear interface to be more object oriented.
579 This should hopefully pave the way for being able to simulate several
581 * Removed unimplemented menu entries.
582 * Various scenery tools changes and enhancements in preparation for adding
583 runways (hopefully for the next release.)
586 * Autopilot can now fly great circle routes.
587 * Incorporated a first stab at some networking code contributed by Oliver
589 * Added Christian Mayer's new weather subsystem.
590 * Started adding support for "external" views ... still needs some work.
591 * Added a flight model acceleration funtion.
592 * Added support for mouse yoke control contributed by David Megginson.
593 * FDM model hertz now definable from the command line.
594 * Added initial timezone support so the user can have better control and more
595 options for setting the starting time of the sim.
596 * We now draw nonexistant tiles as ocean which means we only have to create
597 and distribute tiles that contain some sort of land mass.
599 * Replaced basic render engine with plib's ssg (simple scene graph).
600 * Now expect plib to be installed in it's one true and official location.
601 * Added support for timegm() if it exists which explicitely expects GMT input.
602 * A bit of your basic code reorganization and shuffling.
604 * Removed tools dependency on libgfc. Functionality is now covered by
605 shapelib which has been added into the Tools tree.
606 * Added support for the wonderful GSHHS global land mass data set.
607 * Removed dependecy on process-dem.pl script.
608 * Created a new distributed/parallel tile build system ... hmmm kind of super
609 computer or beowulf style stuff for getting large chunks of scenery built
611 * Only generate tiles that have land mass data since the sim can recreate pure
612 ocean tiles on the fly.
613 * First stab at a water flattening scheme to prevent oceans, lakes, and rivers
614 from running up and down the sides of hills.
615 * Changed the default "Work/" subdirectory layout.
616 * Updates to better handle segment boundaries in preparation for real airport
617 runway and lighting modeling.

631 fixed, distorted textures have been fixed, real coastlines have been added,
632 and many other subtle improvements.
633 * Tools for parallelizing the scenery building tasks. For instance by using
634 20 machines in parallel, scenery for the entire USA can be regenerated in
635 just over 4 hours vs. 70+ hours on a single machine.
636 * Texture scale can be specified (and changed)( in the materials file. The
637 sim must be rerun for the change to take effect.
638 * Windows now uses plib joystick code so rudder pedals should now work.
639 * Now builds against Steve Baker's plib (portable game devel library)
640 distributed separately (www.woodsoup.org/~sbaker/plib/)
641 * Many source code changes for the MacOS port contributed by Darrell
642 Walisser (the port isn't quite there yet ...)
643 * Source code changes for better compiling with the Borland compiler.
644 * Source code changes for better compiling with the native Irix compilers.
645 * Fixed a bug so you can now fly across the international date line (or
646 more precisely the division between longitude = +/-180.
647 * Tweaks to the Astro section contributed by Durk Talsma.
648 * Autopilot improvements contributed by Norman Vine.
649 * Fonts/characters now drawn with texture maps for increased speed.
650 * Instrument panel can be toggled on and off with "P".
651 * GUI interface for tweaking some autopilot parameters.
652 * HUD appearance and layout changes contributed by Norman Vine, includes
653 faster font drawing for much better performance.
654 * Reset function added to reset you to your starting conditions.
655 * GUI function to enter a new airport id (and be transported there)
656 * Added serial output support for an "in-development" full motion cockpit.
657 * "Just in time" texture loading to reduce initial sim loading time.
660 New in 0.59 (This is an intermediate/stepping stone release. Skip this
661 release if you are interested in stability.)
662 * IRIX portability changes and support for native SGI compilers.
663 * Solaris portability tweaks
664 * Incorporated some MacOS portability changes (although the port is not
666 * Changes to allow adjustment of the autopilot settings while it is
668 * Began complete overhaul of scenery generation tools.
669 * Fixed a view frustum culling bug.
670 * separated lib GPC (generic polygon clipper.) GPC is not "freeware" and
671 the author has explicitely refused our request to distribute source code
672 for this library with Flight Gear.
673 * updated installation and getting started guide
674 * switched to a simpler, lighter weight frame rate calculation method.
675 * new tile division scheme.
676 * GPS serial *output* fixes.
677 * Added a nifty halo to both the sun and moon. Preparation for allowing
678 subtle moon lighting effects at night.
679 * Incorporated Jon Berndt's new C++ flight model rewrite.
680 * Autopilot settings can be adjusted while active.
681 * Updates to the instrument panel.
682 * Fixed AOA reading on the HUD.
683 * Added random splash screens.
684 * Modified scenery loader to accept tri-fans.
685 * Other non-backwards compatible changes to scenery file format and tile
690 * Added JSBsim alpha code ... this is Jon S. Berndts alpha FDM rewrite.
691 Still lots to do, but you can watch a balistic flight for a short time.
692 * Renamed Simulator/Flight to Simulator/FDM
693 * Tweaks to assist building FGFS on solaris platforms.
694 * Moved Lib/DEM to Tools/DEM
695 * Started preparations for scenery generation tools overhaul.
696 * More MSVC++ support.
697 * Removed code that made the sun bigger at the horizon since this is just
698 an optical illusion in real life.
699 * Bug fixed so that the sim can start out at an airport below sea level.
702 * Converted to a simpler frame rate counting method.
703 * Fixed the AOA reading on the HUD.
704 * Removed gpc from the Lib section of distribution by request of the
705 gpc Author. The gpc license is unfortunately not compatible with
706 the GPL. I may look for an alternative library, or just require
707 that developers download this library separately.
708 * First slew of changes from the MacOS porting effort contributed by
709 "Robert Puyol" <puyol@abvent.fr>.
710 * Support for an arbitrary number of serial ports + additional serial port
712 * Serial output tweaks to make things more robust and act more like a GPS.
713 * Portability enhancements for Borland, Solaris, and SGI.
714 * Some internal class renaming and reorganizations. fgFLIGHT becomes FGState.
715 fgCONTROLS becomes FGControls.
716 * Started work on an "external" flight model so the sim can be driven from
717 external input (serial port, network, file, etc.)
718 * Fixed a problem that creeped in with setting the initial startup altitude.
719 This could cause an unrecoverable bounce and you'd end up flipped on your
720 back. Should be fixed now.
721 * Sun now appears to grow in size as it gets very low in the horizon.
722 * Fixed a view frustum culling bug where the scene was not accurately culled
723 when your view was anything other than straight forward.
726 * Changed default HUD units to the more standard feet units. You can still
727 use meters by specifying the command line option "--units-meters".
728 * Added some initial joystick support using Steve's joystick interface class.
729 This works great under Linux, but Steve's class now needs to be ported to
730 Windoze and other platforms.
731 * Also added a fall back to the GLUT joystick routines for windows (until
732 we can find better joystick support.)
733 * Added some initial serial port support for acting like gps and outputing
734 nmea data such that could be fed into a flight map software package.
735 * Miscellaneous code clean ups, portability improvements, and optimizations.
736 * Switched to a streams based error/debug logging system that can be
737 completely stripped out for a release build (./configure --without-logging)
738 * Support for cygwin32 b20 compiler (latest release)
739 * Continued progress on instrument panel
740 * Support for starting fgfs at higher resolutions.

744 http://www.cs.man.ac.uk/aig/staff/alan/software/
745 * Brakes (use "b" to toggle)
746 * Added an altitude hold module to the autopilot. Lock your current altitude
747 with "ctrl-a", "cntr-a" again will deactivate. (Also lock your current
748 heading with "ctrl-h", and again to deactivate.)
749 * Added a terrain following module ... "ctrl-t" to activate.
750 * Added an autothrottle ... "ctrl-s" to activate.
751 * Fixes so that terrain tools will work in windoze.
752 * More STL & Compiler compatibility fixes.
753 * Changes to use a Point3 class.
754 * Fixed win95/98 time problem that limited fps to about 18.3
757 * Implimented audio envelopes so that pitch of engine changes with throttle
758 * Textured moon, and rewritten/restructured Astro code.
759 * More optimizations and code cleanups. (Norman Vine, Bernie Bright, Charlie
761 * Bug fixed that was causing odd display artifacts due to a degenerate
762 fragment being created for every tile.
763 * Bug fixed that caused scenery generation to go bad (misplaced fclose on an
764 invalid file descriptor.)
765 * Code changes to support g++ 2.7 STL (from Bernie Bright)
768 * Some initial "GameGLUT" support contributed by Gary R. Van Sickle
769 (tiberius@braemarinc.com)
770 * Tracked down and eliminated some memory access type bugs that were
771 causing segfaults on some platforms, with some compilers using various
773 * Assorted code optimizations submitted by Norman Vine.
776 - Created a new directory Simulator/Airports/ to handle airport data
778 - Created Simulator/Object/ to handle basic rendering objects
779 * Panel code update from Friedemann Reinhard (use --enable-panel to activate)
780 * Contributions from Bernie Bright
781 - Created some new classes to enable pointers-to-functions and
782 pointers-to-class-methods to be treated like objects. These objects
783 can be registered with fgEVENT_MGR.
784 - File "Include/fg_callback.hxx" contains the callback class defns.
785 - Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
786 some minor tweaks to STL usage.
787 - Added file "Include/fg_stl_config.h" to deal with STL portability
788 issues. Added an initial config for egcs (and probably gcc-2.8.x).
789 Don't have access to Visual C++ so I've left that for someone else.
790 - This file is influenced by the stl_config.h file delivered with egcs.
791 - Added "Include/auto_ptr.hxx" which contains an implementation of the
792 STL auto_ptr class which is not provided in all STL implementations
793 and is needed to use the callback classes.
794 - Deleted fgLightUpdate() which was just a wrapper to call
796 - Modified fg_init.cxx to register two method callbacks in place of the
797 old wrapper functions.
798 - The new classes in libmisc.tgz define a stream interface into zlib.
799 I've put these in a new directory, Lib/Misc. Feel free to rename it
800 to something more appropriate. However you'll have to change the
801 include directives in all the other files. Additionally you'll have
802 add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
804 The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
805 test so I've included the required changes in config.tgz.
807 There are a fair few changes to Simulator/Objects as I've moved
808 things around. Loading tiles is quicker but thats not where the delay
809 is. Tile loading takes a few tenths of a second per file on a P200
810 but it seems to be the post-processing that leads to a noticeable
811 blip in framerate. I suppose its time to start profiling to see where
814 I've included a brief description of each archives contents.
819 C++ stream interface into zlib.
820 Taken from zlib-1.1.3/contrib/iostream/.
821 Minor mods for STL compatibility.
822 There's no copyright associated with these so I assume they're
827 FlightGear input stream using gz_ifstream. Tries to open the
828 given filename. If that fails then filename is examined and a
829 ".gz" suffix is removed or appended and that file is opened.
832 A simple timer for benchmarking. Not used in production code.
833 Taken from the Blitz++ project. Covered by GPL.
837 Some simple string manipulation routines.
840 Load airports database using fgstream.
841 Changed fgAIRPORTS to use set<> instead of map<>.
842 Added bool fgAIRPORTS::search() as a neater way doing the lookup.
843 Returns true if found.
846 Modified fgStarsInit() to load stars database using fgstream.
849 Modified fgObjLoad() to use fgstream.
850 Modified fgMATERIAL_MGR::load_lib() to use fgstream.
851 Many changes to fgMATERIAL.
852 Some changes to fgFRAGMENT but I forget what!
855 * Stars added in 8 stages as sky gets darker for a smoother more realistic
857 * rewrote star loader to significantly improve load times.
858 * Tweaked sky brightness and dawn/dusk colors.
859 * Fixed a small problem with moon rendering.
860 * Fog color tries to track the sky color at the center of view in sunrise
861 and sunset situations.
862 * Optimizations from Norman Vine
863 * Code fixes and tweaks from Charlie Hotchkiss.
864 * Added an --enable/disable-sound option.
865 * Added a pause key "p"
866 * Added command line options to specify initial position and orientation.
867 * Added command line option to start in paused or unpaused state.
871 * Various HUD intensities so you can find something that is readable for the
872 current conditions and lighting.
873 * Tie visibility to far clip plane & view frustum culling so reducting
874 visibility can increase frame rates by increasing what is culled.
875 * Fixed stupid bug with misplaced initial position.
876 * Hopefully fixed a bug when parsing system.fgfsrc on windoze.
879 * HUD updates from Charlie Hotchkiss (ladder number rotate w/ ladder, control
880 position indicators are back)
881 * Only draw the PUI cursor if Mesa/Glide/Fullscreen.
883 * Calculate the model view transformation matrix once per tile per iteration.
884 Then glLoadMatrixd() it for each fragment rather than calling push(),
886 * Added a basic splash screen.
887 * Added support for switching between fullscreen and window mode for
889 * added an enable/disable splash screen option
890 * added an enable/disable intro music option
891 * added an enable/disable instrument panel option
892 * added an enable/disable mouse pointer option
893 * Ground collision detection. You can now land or test for collision with
895 * Converted angle of attack scale into a radio altimeter.
898 * Managment of multiple textures
899 * Incorporated Friedemann Reinhard's initial panel code.
900 * Fog mode is now GL_FOG_EXP2 instead of GL_FOG_LINEAR
901 * Build the non-shared pieces of the FG sim as static libs.
904 * Incorporated Steve Baker's PUI user interface library written
905 entirely on top of OpenGL
906 * Incorporated Steve Baker's Audio library which currently only
907 supports Linux, but a win32 port is very close to being done.
908 * Sort object fragments by material property before rendering. This
909 will be a big help to performance when we start including objects
910 with a wide variety of material properties and textures.
911 * Overlapped scenery tiles to reduce the chance of an occasional
912 floating point precission induced gaps.
913 * Fixed a bug in zlib exposed by Borland Win32 compiler.
914 * Impose a maximum triangle area during scenery generation so even
915 very flat areas will get split into a few smaller sub triangles.
916 * Fine grained (fragment level) view frustum culling.
917 * view transformation optimizations -- Norman Vine.
918 * Fixed polygon winding problem in scenery generation, so all
919 tri-strips are wound counter clockwise (opengl default).
922 * Course (per tile) view frustum culling.
923 * Added a command line option to specify --fg-root which will override
925 * Hard coded default locations for FG_ROOT for situations when nothing
926 is specified. Unix = /usr/local/lib/FlightGear Win32 = \FlightGear
927 * Restructured the command line processing code so that it can process
928 these sames comands (one per line) out of a config file.
929 * Added a command line option to specify field of view. This is
930 adjustable at run time using "X / x". Supporting code contributed
934 * Complete C++ re-write of the HUD section.
935 * Miscellaneous bug fixes and tweaks.
938 * Added an option to enable/disable wireframe rendering.
939 * Added an option to enable/disable fog/haze.
940 * Added an option to enable/disable sky blending.
941 * Added an option to select smooth/flat polygon shading.
942 * Added an option to enable full-screen mode.
943 * Added a visual frame rate counter on the HUD. (Contributed by Durk Talsma)
944 * Autopilot updates (Jeff Goeke-Smith)
945 * Added an option to control the number of neighboring tiles that are drawn
948 * Fixed a horible bug that cause the time to be *WAY* off when
949 compiling with the CygWin32 compiler.
950 * Wrap up zlib so we can conditionally compile back in normal behavior
951 on systems that have trouble building zlib.
952 * Minor adjustment to texture coordinate generation to reduce texture
954 * Added a command line option to enable/disable texture maps
955 * Minor transformation adjustments to try to keep scenery tiles closer
956 to (0, 0, 0) GLfloats run out of precision at the distances we need
957 to model the earth, but we can do a bunch of pre-transformations
958 using double floats and then cast to GLfloat once everything is
959 close in where we have less precision problems.
960 * command line option to set starting position by airport ID
961 * Cleaned up initialization sequence to eliminate interdependencies
962 between sun position, lighting, and view position. This creates a
963 valid single pass initialization path.
964 * use already calculated LaRCsim values to create the roll/pitch/yaw
965 transformation matrix
968 * material properties bug fixed when rendering terrain.
969 * bug in sky color generation fixed.
970 * bug in fog color generation fixed.
971 * zlib on the fly decompression/compression support.
972 * more code reorganization and clean ups.
973 * a fixed up 30 arcsec DEM file preprocessor. World wide DEM's are
974 available in this format.
977 * Simple autopilot heading hold contributed by
978 Jeff Goeke-Smith <jgoeke@voyager.net>
979 * More code reorganization and clean ups.
982 * Many autoconf cleanups and tweaks
983 * make and make install work in unix
