2 * Tony Peden contributed a c172 flight model replacement for the
3 Navion. Still needs to be debugged a bit before it is usable.
4 * More MacOS portability fixes.
5 * More Borland C++ fixes.
7 * Fixed a bug in handling windows drive letter, colon "C:" notation.
8 * Minor tweaks to the Astro sub section contributed by Durk Talsma.
9 * GUI updated contributed by Norman Vine.
10 * Fixed a problem with ambiguous constructors in the fgText class.
11 * Updates to JSBsim contributed by Jon Berndt.
12 * Created a tile load queue so that we only load one tile per frame.
13 This isn't entirely satisfactory, but it reduces the length of the
14 pause when crossing a tile boundary with several shorter pauses.
15 * Fixed bug with passing PUI keystrokes on to glut.
16 * Fixed a bug in tilecache size which caused occasional tiles to drop
17 out when more than one row is scheduled "simultaneously".
18 * Changes to scenery building tools to handle sliver detection and
20 * Fixed several other minor bugs in the scenery creation tools.
21 * Added urban area support to scenery creation tools.
22 * Made the parallel scenery building tools a bit more robust if a
23 requested client machine happens to be offline by pinging it first
24 to see if it is alive.
25 * Added support for libgpc's new hole tracking interface.
28 * Tons of improvements with scenery creation. Inter-tile gaps have been
29 fixed, distorted textures have been fixed, real coastlines have been added,
30 and many other subtle improvements.
31 * Tools for parallelizing the scenery building tasks. For instance by using
32 20 machines in parallel, scenery for the entire USA can be regenerated in
33 just over 4 hours vs. 70+ hours on a single machine.
34 * Texture scale can be specified (and changed)( in the materials file. The
35 sim must be rerun for the change to take effect.
36 * Windows now uses plib joystick code so rudder pedals should now work.
37 * Now builds against Steve Baker's plib (portable game devel library)
38 distributed separately (www.woodsoup.org/~sbaker/plib/)
39 * Many source code changes for the MacOS port contributed by Darrell
40 Walisser (the port isn't quite there yet ...)
41 * Source code changes for better compiling with the Borland compiler.
42 * Source code changes for better compiling with the native Irix compilers.
43 * Fixed a bug so you can now fly across the international date line (or
44 more precisely the division between longitude = +/-180.
45 * Tweaks to the Astro section contributed by Durk Talsma.
46 * Autopilot improvements contributed by Norman Vine.
47 * Fonts/characters now drawn with texture maps for increased speed.
48 * Instrument panel can be toggled on and off with "P".
49 * GUI interface for tweaking some autopilot parameters.
50 * HUD appearance and layout changes contributed by Norman Vine, includes
51 faster font drawing for much better performance.
52 * Reset function added to reset you to your starting conditions.
53 * GUI function to enter a new airport id (and be transported there)
54 * Added serial output support for an "in-development" full motion cockpit.
55 * "Just in time" texture loading to reduce initial sim loading time.
58 New in 0.59 (This is an intermediate/stepping stone release. Skip this
59 release if you are interested in stability.)
60 * IRIX portability changes and support for native SGI compilers.
61 * Solaris portability tweaks
62 * Incorporated some MacOS portability changes (although the port is not
64 * Changes to allow adjustment of the autopilot settings while it is
66 * Began complete overhaul of scenery generation tools.
67 * Fixed a view frustum culling bug.
68 * separated lib GPC (generic polygon clipper.) GPC is not "freeware" and
69 the author has explicitely refused our request to distribute source code
70 for this library with Flight Gear.
71 * updated installation and getting started guide
72 * switched to a simpler, lighter weight frame rate calculation method.
73 * new tile division scheme.
74 * GPS serial *output* fixes.
75 * Added a nifty halo to both the sun and moon. Preparation for allowing
76 subtle moon lighting effects at night.
77 * Incorporated Jon Berndt's new C++ flight model rewrite.
78 * Autopilot settings can be adjusted while active.
79 * Updates to the instrument panel.
80 * Fixed AOA reading on the HUD.
81 * Added random splash screens.
82 * Modified scenery loader to accept tri-fans.
83 * Other non-backwards compatible changes to scenery file format and tile
88 * Added JSBsim alpha code ... this is Jon S. Berndts alpha FDM rewrite.
89 Still lots to do, but you can watch a balistic flight for a short time.
90 * Renamed Simulator/Flight to Simulator/FDM
91 * Tweaks to assist building FGFS on solaris platforms.
92 * Moved Lib/DEM to Tools/DEM
93 * Started preparations for scenery generation tools overhaul.
94 * More MSVC++ support.
95 * Removed code that made the sun bigger at the horizon since this is just
96 an optical illusion in real life.
97 * Bug fixed so that the sim can start out at an airport below sea level.
100 * Converted to a simpler frame rate counting method.
101 * Fixed the AOA reading on the HUD.
102 * Removed gpc from the Lib section of distribution by request of the
103 gpc Author. The gpc license is unfortunately not compatible with
104 the GPL. I may look for an alternative library, or just require
105 that developers download this library separately.
106 * First slew of changes from the MacOS porting effort contributed by
107 "Robert Puyol" <puyol@abvent.fr>.
108 * Support for an arbitrary number of serial ports + additional serial port
110 * Serial output tweaks to make things more robust and act more like a GPS.
111 * Portability enhancements for Borland, Solaris, and SGI.
112 * Some internal class renaming and reorganizations. fgFLIGHT becomes FGState.
113 fgCONTROLS becomes FGControls.
114 * Started work on an "external" flight model so the sim can be driven from
115 external input (serial port, network, file, etc.)
116 * Fixed a problem that creeped in with setting the initial startup altitude.
117 This could cause an unrecoverable bounce and you'd end up flipped on your
118 back. Should be fixed now.
119 * Sun now appears to grow in size as it gets very low in the horizon.
120 * Fixed a view frustum culling bug where the scene was not accurately culled
121 when your view was anything other than straight forward.
124 * Changed default HUD units to the more standard feet units. You can still
125 use meters by specifying the command line option "--units-meters".
126 * Added some initial joystick support using Steve's joystick interface class.
127 This works great under Linux, but Steve's class now needs to be ported to
128 Windoze and other platforms.
129 * Also added a fall back to the GLUT joystick routines for windows (until
130 we can find better joystick support.)
131 * Added some initial serial port support for acting like gps and outputing
132 nmea data such that could be fed into a flight map software package.
133 * Miscellaneous code clean ups, portability improvements, and optimizations.
134 * Switched to a streams based error/debug logging system that can be
135 completely stripped out for a release build (./configure --without-logging)
136 * Support for cygwin32 b20 compiler (latest release)
137 * Continued progress on instrument panel
138 * Support for starting fgfs at higher resolutions.
141 * New version of gpc (generic polygon clipping library) from
142 http://www.cs.man.ac.uk/aig/staff/alan/software/
143 * Brakes (use "b" to toggle)
144 * Added an altitude hold module to the autopilot. Lock your current altitude
145 with "ctrl-a", "cntr-a" again will deactivate. (Also lock your current
146 heading with "ctrl-h", and again to deactivate.)
147 * Added a terrain following module ... "ctrl-t" to activate.
148 * Added an autothrottle ... "ctrl-s" to activate.
149 * Fixes so that terrain tools will work in windoze.
150 * More STL & Compiler compatibility fixes.
151 * Changes to use a Point3 class.
152 * Fixed win95/98 time problem that limited fps to about 18.3
155 * Implimented audio envelopes so that pitch of engine changes with throttle
156 * Textured moon, and rewritten/restructured Astro code.
157 * More optimizations and code cleanups. (Norman Vine, Bernie Bright, Charlie
159 * Bug fixed that was causing odd display artifacts due to a degenerate
160 fragment being created for every tile.
161 * Bug fixed that caused scenery generation to go bad (misplaced fclose on an
162 invalid file descriptor.)
163 * Code changes to support g++ 2.7 STL (from Bernie Bright)
166 * Some initial "GameGLUT" support contributed by Gary R. Van Sickle
167 (tiberius@braemarinc.com)
168 * Tracked down and eliminated some memory access type bugs that were
169 causing segfaults on some platforms, with some compilers using various
171 * Assorted code optimizations submitted by Norman Vine.
174 - Created a new directory Simulator/Airports/ to handle airport data
176 - Created Simulator/Object/ to handle basic rendering objects
177 * Panel code update from Friedemann Reinhard (use --enable-panel to activate)
178 * Contributions from Bernie Bright
179 - Created some new classes to enable pointers-to-functions and
180 pointers-to-class-methods to be treated like objects. These objects
181 can be registered with fgEVENT_MGR.
182 - File "Include/fg_callback.hxx" contains the callback class defns.
183 - Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
184 some minor tweaks to STL usage.
185 - Added file "Include/fg_stl_config.h" to deal with STL portability
186 issues. Added an initial config for egcs (and probably gcc-2.8.x).
187 Don't have access to Visual C++ so I've left that for someone else.
188 - This file is influenced by the stl_config.h file delivered with egcs.
189 - Added "Include/auto_ptr.hxx" which contains an implementation of the
190 STL auto_ptr class which is not provided in all STL implementations
191 and is needed to use the callback classes.
192 - Deleted fgLightUpdate() which was just a wrapper to call
194 - Modified fg_init.cxx to register two method callbacks in place of the
195 old wrapper functions.
196 - The new classes in libmisc.tgz define a stream interface into zlib.
197 I've put these in a new directory, Lib/Misc. Feel free to rename it
198 to something more appropriate. However you'll have to change the
199 include directives in all the other files. Additionally you'll have
200 add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
202 The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
203 test so I've included the required changes in config.tgz.
205 There are a fair few changes to Simulator/Objects as I've moved
206 things around. Loading tiles is quicker but thats not where the delay
207 is. Tile loading takes a few tenths of a second per file on a P200
208 but it seems to be the post-processing that leads to a noticeable
209 blip in framerate. I suppose its time to start profiling to see where
212 I've included a brief description of each archives contents.
217 C++ stream interface into zlib.
218 Taken from zlib-1.1.3/contrib/iostream/.
219 Minor mods for STL compatibility.
220 There's no copyright associated with these so I assume they're
225 FlightGear input stream using gz_ifstream. Tries to open the
226 given filename. If that fails then filename is examined and a
227 ".gz" suffix is removed or appended and that file is opened.
230 A simple timer for benchmarking. Not used in production code.
231 Taken from the Blitz++ project. Covered by GPL.
235 Some simple string manipulation routines.
238 Load airports database using fgstream.
239 Changed fgAIRPORTS to use set<> instead of map<>.
240 Added bool fgAIRPORTS::search() as a neater way doing the lookup.
241 Returns true if found.
244 Modified fgStarsInit() to load stars database using fgstream.
247 Modified fgObjLoad() to use fgstream.
248 Modified fgMATERIAL_MGR::load_lib() to use fgstream.
249 Many changes to fgMATERIAL.
250 Some changes to fgFRAGMENT but I forget what!
253 * Stars added in 8 stages as sky gets darker for a smoother more realistic
255 * rewrote star loader to significantly improve load times.
256 * Tweaked sky brightness and dawn/dusk colors.
257 * Fixed a small problem with moon rendering.
258 * Fog color tries to track the sky color at the center of view in sunrise
259 and sunset situations.
260 * Optimizations from Norman Vine
261 * Code fixes and tweaks from Charlie Hotchkiss.
262 * Added an --enable/disable-sound option.
263 * Added a pause key "p"
264 * Added command line options to specify initial position and orientation.
265 * Added command line option to start in paused or unpaused state.
269 * Various HUD intensities so you can find something that is readable for the
270 current conditions and lighting.
271 * Tie visibility to far clip plane & view frustum culling so reducting
272 visibility can increase frame rates by increasing what is culled.
273 * Fixed stupid bug with misplaced initial position.
274 * Hopefully fixed a bug when parsing system.fgfsrc on windoze.
277 * HUD updates from Charlie Hotchkiss (ladder number rotate w/ ladder, control
278 position indicators are back)
279 * Only draw the PUI cursor if Mesa/Glide/Fullscreen.
281 * Calculate the model view transformation matrix once per tile per iteration.
282 Then glLoadMatrixd() it for each fragment rather than calling push(),
284 * Added a basic splash screen.
285 * Added support for switching between fullscreen and window mode for
287 * added an enable/disable splash screen option
288 * added an enable/disable intro music option
289 * added an enable/disable instrument panel option
290 * added an enable/disable mouse pointer option
291 * Ground collision detection. You can now land or test for collision with
293 * Converted angle of attack scale into a radio altimeter.
296 * Managment of multiple textures
297 * Incorporated Friedemann Reinhard's initial panel code.
298 * Fog mode is now GL_FOG_EXP2 instead of GL_FOG_LINEAR
299 * Build the non-shared pieces of the FG sim as static libs.
302 * Incorporated Steve Baker's PUI user interface library written
303 entirely on top of OpenGL
304 * Incorporated Steve Baker's Audio library which currently only
305 supports Linux, but a win32 port is very close to being done.
306 * Sort object fragments by material property before rendering. This
307 will be a big help to performance when we start including objects
308 with a wide variety of material properties and textures.
309 * Overlapped scenery tiles to reduce the chance of an occasional
310 floating point precission induced gaps.
311 * Fixed a bug in zlib exposed by Borland Win32 compiler.
312 * Impose a maximum triangle area during scenery generation so even
313 very flat areas will get split into a few smaller sub triangles.
314 * Fine grained (fragment level) view frustum culling.
315 * view transformation optimizations -- Norman Vine.
316 * Fixed polygon winding problem in scenery generation, so all
317 tri-strips are wound counter clockwise (opengl default).
320 * Course (per tile) view frustum culling.
321 * Added a command line option to specify --fg-root which will override
323 * Hard coded default locations for FG_ROOT for situations when nothing
324 is specified. Unix = /usr/local/lib/FlightGear Win32 = \FlightGear
325 * Restructured the command line processing code so that it can process
326 these sames comands (one per line) out of a config file.
327 * Added a command line option to specify field of view. This is
328 adjustable at run time using "X / x". Supporting code contributed
332 * Complete C++ re-write of the HUD section.
333 * Miscellaneous bug fixes and tweaks.
336 * Added an option to enable/disable wireframe rendering.
337 * Added an option to enable/disable fog/haze.
338 * Added an option to enable/disable sky blending.
339 * Added an option to select smooth/flat polygon shading.
340 * Added an option to enable full-screen mode.
341 * Added a visual frame rate counter on the HUD. (Contributed by Durk Talsma)
342 * Autopilot updates (Jeff Goeke-Smith)
343 * Added an option to control the number of neighboring tiles that are drawn
346 * Fixed a horible bug that cause the time to be *WAY* off when
347 compiling with the CygWin32 compiler.
348 * Wrap up zlib so we can conditionally compile back in normal behavior
349 on systems that have trouble building zlib.
350 * Minor adjustment to texture coordinate generation to reduce texture
352 * Added a command line option to enable/disable texture maps
353 * Minor transformation adjustments to try to keep scenery tiles closer
354 to (0, 0, 0) GLfloats run out of precision at the distances we need
355 to model the earth, but we can do a bunch of pre-transformations
356 using double floats and then cast to GLfloat once everything is
357 close in where we have less precision problems.
358 * command line option to set starting position by airport ID
359 * Cleaned up initialization sequence to eliminate interdependencies
360 between sun position, lighting, and view position. This creates a
361 valid single pass initialization path.
362 * use already calculated LaRCsim values to create the roll/pitch/yaw
363 transformation matrix
366 * material properties bug fixed when rendering terrain.
367 * bug in sky color generation fixed.
368 * bug in fog color generation fixed.
369 * zlib on the fly decompression/compression support.
370 * more code reorganization and clean ups.
371 * a fixed up 30 arcsec DEM file preprocessor. World wide DEM's are
372 available in this format.
375 * Simple autopilot heading hold contributed by
376 Jeff Goeke-Smith <jgoeke@voyager.net>
377 * More code reorganization and clean ups.
380 * Many autoconf cleanups and tweaks
381 * make and make install work in unix

384 * added the Tools directory into the main source tree
387 * Gnu automake/autoconf/libtool make system
388 * Initial texture support
