7 * Added a flight model acceleration funtion.
8 * Added support for mouse yoke control contributed by David Megginson.
9 * FDM model hertz now definable from the command line.
10 * Added initial timezone support so the user can have better control and more
11 options for setting the starting time of the sim.
12 * We now draw nonexistant tiles as ocean which means we only have to create
13 and distribute tiles that contain some sort of land mass.
15 * Replaced basic render engine with plib's ssg (simple scene graph).
16 * Now expect plib to be installed in it's one true and official location.
17 * Added support for timegm() if it exists which explicitely expects GMT input.
18 * A bit of your basic code reorganization and shuffling.
20 * Removed tools dependency on libgfc. Functionality is now covered by
21 shapelib which has been added into the Tools tree.
22 * Added support for the wonderful GSHHS global land mass data set.
23 * Removed dependecy on process-dem.pl script.
24 * Created a new distributed/parallel tile build system ... hmmm kind of super
25 computer or beowulf style stuff for getting large chunks of scenery built
27 * Only generate tiles that have land mass data since the sim can recreate pure
28 ocean tiles on the fly.
29 * First stab at a water flattening scheme to prevent oceans, lakes, and rivers
30 from running up and down the sides of hills.
31 * Changed the default "Work/" subdirectory layout.

46 * Tons of improvements with scenery creation. Inter-tile gaps have been
47 fixed, distorted textures have been fixed, real coastlines have been added,
48 and many other subtle improvements.
49 * Tools for parallelizing the scenery building tasks. For instance by using
50 20 machines in parallel, scenery for the entire USA can be regenerated in
51 just over 4 hours vs. 70+ hours on a single machine.
52 * Texture scale can be specified (and changed)( in the materials file. The
53 sim must be rerun for the change to take effect.
54 * Windows now uses plib joystick code so rudder pedals should now work.
55 * Now builds against Steve Baker's plib (portable game devel library)
56 distributed separately (www.woodsoup.org/~sbaker/plib/)
57 * Many source code changes for the MacOS port contributed by Darrell
58 Walisser (the port isn't quite there yet ...)
59 * Source code changes for better compiling with the Borland compiler.
60 * Source code changes for better compiling with the native Irix compilers.
61 * Fixed a bug so you can now fly across the international date line (or
62 more precisely the division between longitude = +/-180.
63 * Tweaks to the Astro section contributed by Durk Talsma.
64 * Autopilot improvements contributed by Norman Vine.
65 * Fonts/characters now drawn with texture maps for increased speed.

69 faster font drawing for much better performance.
70 * Reset function added to reset you to your starting conditions.
71 * GUI function to enter a new airport id (and be transported there)
72 * Added serial output support for an "in-development" full motion cockpit.
73 * "Just in time" texture loading to reduce initial sim loading time.
76 New in 0.59 (This is an intermediate/stepping stone release. Skip this
77 release if you are interested in stability.)
78 * IRIX portability changes and support for native SGI compilers.
79 * Solaris portability tweaks
80 * Incorporated some MacOS portability changes (although the port is not
82 * Changes to allow adjustment of the autopilot settings while it is
84 * Began complete overhaul of scenery generation tools.
85 * Fixed a view frustum culling bug.
86 * separated lib GPC (generic polygon clipper.) GPC is not "freeware" and
87 the author has explicitely refused our request to distribute source code
88 for this library with Flight Gear.
89 * updated installation and getting started guide
90 * switched to a simpler, lighter weight frame rate calculation method.
91 * new tile division scheme.
92 * GPS serial *output* fixes.
93 * Added a nifty halo to both the sun and moon. Preparation for allowing
94 subtle moon lighting effects at night.
95 * Incorporated Jon Berndt's new C++ flight model rewrite.
96 * Autopilot settings can be adjusted while active.
97 * Updates to the instrument panel.
98 * Fixed AOA reading on the HUD.
99 * Added random splash screens.
100 * Modified scenery loader to accept tri-fans.
101 * Other non-backwards compatible changes to scenery file format and tile
106 * Added JSBsim alpha code ... this is Jon S. Berndts alpha FDM rewrite.
107 Still lots to do, but you can watch a balistic flight for a short time.
108 * Renamed Simulator/Flight to Simulator/FDM
109 * Tweaks to assist building FGFS on solaris platforms.
110 * Moved Lib/DEM to Tools/DEM
111 * Started preparations for scenery generation tools overhaul.
112 * More MSVC++ support.
113 * Removed code that made the sun bigger at the horizon since this is just
114 an optical illusion in real life.
115 * Bug fixed so that the sim can start out at an airport below sea level.
118 * Converted to a simpler frame rate counting method.
119 * Fixed the AOA reading on the HUD.
120 * Removed gpc from the Lib section of distribution by request of the
121 gpc Author. The gpc license is unfortunately not compatible with
122 the GPL. I may look for an alternative library, or just require
123 that developers download this library separately.
124 * First slew of changes from the MacOS porting effort contributed by
125 "Robert Puyol" <puyol@abvent.fr>.
126 * Support for an arbitrary number of serial ports + additional serial port
128 * Serial output tweaks to make things more robust and act more like a GPS.
129 * Portability enhancements for Borland, Solaris, and SGI.
130 * Some internal class renaming and reorganizations. fgFLIGHT becomes FGState.
131 fgCONTROLS becomes FGControls.
132 * Started work on an "external" flight model so the sim can be driven from
133 external input (serial port, network, file, etc.)
134 * Fixed a problem that creeped in with setting the initial startup altitude.
135 This could cause an unrecoverable bounce and you'd end up flipped on your
136 back. Should be fixed now.
137 * Sun now appears to grow in size as it gets very low in the horizon.
138 * Fixed a view frustum culling bug where the scene was not accurately culled
139 when your view was anything other than straight forward.
142 * Changed default HUD units to the more standard feet units. You can still
143 use meters by specifying the command line option "--units-meters".
144 * Added some initial joystick support using Steve's joystick interface class.
145 This works great under Linux, but Steve's class now needs to be ported to
146 Windoze and other platforms.
147 * Also added a fall back to the GLUT joystick routines for windows (until
148 we can find better joystick support.)
149 * Added some initial serial port support for acting like gps and outputing
150 nmea data such that could be fed into a flight map software package.
151 * Miscellaneous code clean ups, portability improvements, and optimizations.
152 * Switched to a streams based error/debug logging system that can be
153 completely stripped out for a release build (./configure --without-logging)
154 * Support for cygwin32 b20 compiler (latest release)
155 * Continued progress on instrument panel
156 * Support for starting fgfs at higher resolutions.

160 http://www.cs.man.ac.uk/aig/staff/alan/software/
161 * Brakes (use "b" to toggle)
162 * Added an altitude hold module to the autopilot. Lock your current altitude
163 with "ctrl-a", "cntr-a" again will deactivate. (Also lock your current
164 heading with "ctrl-h", and again to deactivate.)
165 * Added a terrain following module ... "ctrl-t" to activate.
166 * Added an autothrottle ... "ctrl-s" to activate.
167 * Fixes so that terrain tools will work in windoze.
168 * More STL & Compiler compatibility fixes.
169 * Changes to use a Point3 class.
170 * Fixed win95/98 time problem that limited fps to about 18.3
173 * Implimented audio envelopes so that pitch of engine changes with throttle
174 * Textured moon, and rewritten/restructured Astro code.
175 * More optimizations and code cleanups. (Norman Vine, Bernie Bright, Charlie
177 * Bug fixed that was causing odd display artifacts due to a degenerate
178 fragment being created for every tile.
179 * Bug fixed that caused scenery generation to go bad (misplaced fclose on an
180 invalid file descriptor.)
181 * Code changes to support g++ 2.7 STL (from Bernie Bright)
184 * Some initial "GameGLUT" support contributed by Gary R. Van Sickle
185 (tiberius@braemarinc.com)
186 * Tracked down and eliminated some memory access type bugs that were
187 causing segfaults on some platforms, with some compilers using various
189 * Assorted code optimizations submitted by Norman Vine.
192 - Created a new directory Simulator/Airports/ to handle airport data
194 - Created Simulator/Object/ to handle basic rendering objects
195 * Panel code update from Friedemann Reinhard (use --enable-panel to activate)
196 * Contributions from Bernie Bright
197 - Created some new classes to enable pointers-to-functions and
198 pointers-to-class-methods to be treated like objects. These objects
199 can be registered with fgEVENT_MGR.
200 - File "Include/fg_callback.hxx" contains the callback class defns.
201 - Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
202 some minor tweaks to STL usage.
203 - Added file "Include/fg_stl_config.h" to deal with STL portability
204 issues. Added an initial config for egcs (and probably gcc-2.8.x).
205 Don't have access to Visual C++ so I've left that for someone else.
206 - This file is influenced by the stl_config.h file delivered with egcs.
207 - Added "Include/auto_ptr.hxx" which contains an implementation of the
208 STL auto_ptr class which is not provided in all STL implementations
209 and is needed to use the callback classes.
210 - Deleted fgLightUpdate() which was just a wrapper to call
212 - Modified fg_init.cxx to register two method callbacks in place of the
213 old wrapper functions.
214 - The new classes in libmisc.tgz define a stream interface into zlib.
215 I've put these in a new directory, Lib/Misc. Feel free to rename it
216 to something more appropriate. However you'll have to change the
217 include directives in all the other files. Additionally you'll have
218 add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
220 The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
221 test so I've included the required changes in config.tgz.
223 There are a fair few changes to Simulator/Objects as I've moved
224 things around. Loading tiles is quicker but thats not where the delay
225 is. Tile loading takes a few tenths of a second per file on a P200
226 but it seems to be the post-processing that leads to a noticeable
227 blip in framerate. I suppose its time to start profiling to see where
230 I've included a brief description of each archives contents.
235 C++ stream interface into zlib.
236 Taken from zlib-1.1.3/contrib/iostream/.
237 Minor mods for STL compatibility.
238 There's no copyright associated with these so I assume they're
243 FlightGear input stream using gz_ifstream. Tries to open the
244 given filename. If that fails then filename is examined and a
245 ".gz" suffix is removed or appended and that file is opened.
248 A simple timer for benchmarking. Not used in production code.
249 Taken from the Blitz++ project. Covered by GPL.
253 Some simple string manipulation routines.
256 Load airports database using fgstream.
257 Changed fgAIRPORTS to use set<> instead of map<>.
258 Added bool fgAIRPORTS::search() as a neater way doing the lookup.
259 Returns true if found.
262 Modified fgStarsInit() to load stars database using fgstream.
265 Modified fgObjLoad() to use fgstream.
266 Modified fgMATERIAL_MGR::load_lib() to use fgstream.
267 Many changes to fgMATERIAL.
268 Some changes to fgFRAGMENT but I forget what!
271 * Stars added in 8 stages as sky gets darker for a smoother more realistic
273 * rewrote star loader to significantly improve load times.
274 * Tweaked sky brightness and dawn/dusk colors.
275 * Fixed a small problem with moon rendering.
276 * Fog color tries to track the sky color at the center of view in sunrise
277 and sunset situations.
278 * Optimizations from Norman Vine
279 * Code fixes and tweaks from Charlie Hotchkiss.
280 * Added an --enable/disable-sound option.
281 * Added a pause key "p"
282 * Added command line options to specify initial position and orientation.
283 * Added command line option to start in paused or unpaused state.
287 * Various HUD intensities so you can find something that is readable for the
288 current conditions and lighting.
289 * Tie visibility to far clip plane & view frustum culling so reducting
290 visibility can increase frame rates by increasing what is culled.
291 * Fixed stupid bug with misplaced initial position.
292 * Hopefully fixed a bug when parsing system.fgfsrc on windoze.
295 * HUD updates from Charlie Hotchkiss (ladder number rotate w/ ladder, control
296 position indicators are back)
297 * Only draw the PUI cursor if Mesa/Glide/Fullscreen.
299 * Calculate the model view transformation matrix once per tile per iteration.
300 Then glLoadMatrixd() it for each fragment rather than calling push(),
302 * Added a basic splash screen.
303 * Added support for switching between fullscreen and window mode for
305 * added an enable/disable splash screen option
306 * added an enable/disable intro music option
307 * added an enable/disable instrument panel option
308 * added an enable/disable mouse pointer option
309 * Ground collision detection. You can now land or test for collision with
311 * Converted angle of attack scale into a radio altimeter.
314 * Managment of multiple textures
315 * Incorporated Friedemann Reinhard's initial panel code.
316 * Fog mode is now GL_FOG_EXP2 instead of GL_FOG_LINEAR
317 * Build the non-shared pieces of the FG sim as static libs.
320 * Incorporated Steve Baker's PUI user interface library written
321 entirely on top of OpenGL
322 * Incorporated Steve Baker's Audio library which currently only
323 supports Linux, but a win32 port is very close to being done.
324 * Sort object fragments by material property before rendering. This
325 will be a big help to performance when we start including objects
326 with a wide variety of material properties and textures.
327 * Overlapped scenery tiles to reduce the chance of an occasional
328 floating point precission induced gaps.
329 * Fixed a bug in zlib exposed by Borland Win32 compiler.
330 * Impose a maximum triangle area during scenery generation so even
331 very flat areas will get split into a few smaller sub triangles.
332 * Fine grained (fragment level) view frustum culling.
333 * view transformation optimizations -- Norman Vine.
334 * Fixed polygon winding problem in scenery generation, so all
335 tri-strips are wound counter clockwise (opengl default).
338 * Course (per tile) view frustum culling.
339 * Added a command line option to specify --fg-root which will override
341 * Hard coded default locations for FG_ROOT for situations when nothing
342 is specified. Unix = /usr/local/lib/FlightGear Win32 = \FlightGear
343 * Restructured the command line processing code so that it can process
344 these sames comands (one per line) out of a config file.
345 * Added a command line option to specify field of view. This is
346 adjustable at run time using "X / x". Supporting code contributed
350 * Complete C++ re-write of the HUD section.
351 * Miscellaneous bug fixes and tweaks.
354 * Added an option to enable/disable wireframe rendering.
355 * Added an option to enable/disable fog/haze.
356 * Added an option to enable/disable sky blending.
357 * Added an option to select smooth/flat polygon shading.
358 * Added an option to enable full-screen mode.
359 * Added a visual frame rate counter on the HUD. (Contributed by Durk Talsma)
360 * Autopilot updates (Jeff Goeke-Smith)
361 * Added an option to control the number of neighboring tiles that are drawn
364 * Fixed a horible bug that cause the time to be *WAY* off when
365 compiling with the CygWin32 compiler.
366 * Wrap up zlib so we can conditionally compile back in normal behavior
367 on systems that have trouble building zlib.
368 * Minor adjustment to texture coordinate generation to reduce texture
370 * Added a command line option to enable/disable texture maps
371 * Minor transformation adjustments to try to keep scenery tiles closer
372 to (0, 0, 0) GLfloats run out of precision at the distances we need
373 to model the earth, but we can do a bunch of pre-transformations
374 using double floats and then cast to GLfloat once everything is
375 close in where we have less precision problems.
376 * command line option to set starting position by airport ID
377 * Cleaned up initialization sequence to eliminate interdependencies
378 between sun position, lighting, and view position. This creates a
379 valid single pass initialization path.
380 * use already calculated LaRCsim values to create the roll/pitch/yaw
381 transformation matrix
384 * material properties bug fixed when rendering terrain.
385 * bug in sky color generation fixed.
386 * bug in fog color generation fixed.
387 * zlib on the fly decompression/compression support.
388 * more code reorganization and clean ups.
389 * a fixed up 30 arcsec DEM file preprocessor. World wide DEM's are
390 available in this format.
393 * Simple autopilot heading hold contributed by
394 Jeff Goeke-Smith <jgoeke@voyager.net>
395 * More code reorganization and clean ups.
398 * Many autoconf cleanups and tweaks
399 * make and make install work in unix
