3 (This is an intermediate/stepping stone release. Skip this if you are
4 interested in stability.)
6 * IRIX portability changes and support for native SGI compilers.
7 * Solaris portability tweaks
8 * Incorporated some MacOS portability changes (although the port is not
10 * Changes to allow adjustment of the autopilot settings while it is
12 * Began complete overhaul of scenery generation tools.
13 * Fixed a view frustum culling bug.
14 * separated lib GPC (generic polygon clipper.) GPC is not "freeware" and
15 the author has explicitely refused our request to distribute source code
16 for this library with Flight Gear.
17 * updated installation and getting started guide
18 * switched to a simpler, lighter weight frame rate calculation method.
19 * new tile division scheme.
20 * GPS serial *output* fixes.
21 * Added a nifty halo to both the sun and moon. Preparation for allowing
22 subtle moon lighting effects at night.
23 * Incorporated Jon Berndt's new C++ flight model rewrite.
24 * Autopilot settings can be adjusted while active.
25 * Updates to the instrument panel.
26 * Fixed AOA reading on the HUD.
27 * Added random splash screens.
28 * Modified scenery loader to accept tri-fans.
29 * Other non-backwards compatible changes to scenery file format and tile
34 * Added JSBsim alpha code ... this is Jon S. Berndts alpha FDM rewrite.
35 Still lots to do, but you can watch a balistic flight for a short time.
36 * Renamed Simulator/Flight to Simulator/FDM
37 * Tweaks to assist building FGFS on solaris platforms.
38 * Moved Lib/DEM to Tools/DEM
39 * Started preparations for scenery generation tools overhaul.
40 * More MSVC++ support.
41 * Removed code that made the sun bigger at the horizon since this is just
42 an optical illusion in real life.
43 * Bug fixed so that the sim can start out at an airport below sea level.
46 * Converted to a simpler frame rate counting method.
47 * Fixed the AOA reading on the HUD.
48 * Removed gpc from the Lib section of distribution by request of the
49 gpc Author. The gpc license is unfortunately not compatible with
50 the GPL. I may look for an alternative library, or just require
51 that developers download this library separately.
52 * First slew of changes from the MacOS porting effort contributed by
53 "Robert Puyol" <puyol@abvent.fr>.
54 * Support for an arbitrary number of serial ports + additional serial port
56 * Serial output tweaks to make things more robust and act more like a GPS.
57 * Portability enhancements for Borland, Solaris, and SGI.
58 * Some internal class renaming and reorganizations. fgFLIGHT becomes FGState.
59 fgCONTROLS becomes FGControls.
60 * Started work on an "external" flight model so the sim can be driven from
61 external input (serial port, network, file, etc.)
62 * Fixed a problem that creeped in with setting the initial startup altitude.
63 This could cause an unrecoverable bounce and you'd end up flipped on your
64 back. Should be fixed now.
65 * Sun now appears to grow in size as it gets very low in the horizon.
66 * Fixed a view frustum culling bug where the scene was not accurately culled
67 when your view was anything other than straight forward.
70 * Changed default HUD units to the more standard feet units. You can still
71 use meters by specifying the command line option "--units-meters".
72 * Added some initial joystick support using Steve's joystick interface class.
73 This works great under Linux, but Steve's class now needs to be ported to
74 Windoze and other platforms.
75 * Also added a fall back to the GLUT joystick routines for windows (until
76 we can find better joystick support.)
77 * Added some initial serial port support for acting like gps and outputing
78 nmea data such that could be fed into a flight map software package.
79 * Miscellaneous code clean ups, portability improvements, and optimizations.
80 * Switched to a streams based error/debug logging system that can be
81 completely stripped out for a release build (./configure --without-logging)
82 * Support for cygwin32 b20 compiler (latest release)
83 * Continued progress on instrument panel
84 * Support for starting fgfs at higher resolutions.
87 * New version of gpc (generic polygon clipping library) from
88 http://www.cs.man.ac.uk/aig/staff/alan/software/
89 * Brakes (use "b" to toggle)
90 * Added an altitude hold module to the autopilot. Lock your current altitude
91 with "ctrl-a", "cntr-a" again will deactivate. (Also lock your current
92 heading with "ctrl-h", and again to deactivate.)
93 * Added a terrain following module ... "ctrl-t" to activate.
94 * Added an autothrottle ... "ctrl-s" to activate.
95 * Fixes so that terrain tools will work in windoze.
96 * More STL & Compiler compatibility fixes.
97 * Changes to use a Point3 class.
98 * Fixed win95/98 time problem that limited fps to about 18.3
101 * Implimented audio envelopes so that pitch of engine changes with throttle
102 * Textured moon, and rewritten/restructured Astro code.
103 * More optimizations and code cleanups. (Norman Vine, Bernie Bright, Charlie
105 * Bug fixed that was causing odd display artifacts due to a degenerate
106 fragment being created for every tile.
107 * Bug fixed that caused scenery generation to go bad (misplaced fclose on an
108 invalid file descriptor.)
109 * Code changes to support g++ 2.7 STL (from Bernie Bright)
112 * Some initial "GameGLUT" support contributed by Gary R. Van Sickle
113 (tiberius@braemarinc.com)
114 * Tracked down and eliminated some memory access type bugs that were
115 causing segfaults on some platforms, with some compilers using various
117 * Assorted code optimizations submitted by Norman Vine.
120 - Created a new directory Simulator/Airports/ to handle airport data
122 - Created Simulator/Object/ to handle basic rendering objects
123 * Panel code update from Friedemann Reinhard (use --enable-panel to activate)
124 * Contributions from Bernie Bright
125 - Created some new classes to enable pointers-to-functions and
126 pointers-to-class-methods to be treated like objects. These objects
127 can be registered with fgEVENT_MGR.
128 - File "Include/fg_callback.hxx" contains the callback class defns.
129 - Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
130 some minor tweaks to STL usage.
131 - Added file "Include/fg_stl_config.h" to deal with STL portability
132 issues. Added an initial config for egcs (and probably gcc-2.8.x).
133 Don't have access to Visual C++ so I've left that for someone else.
134 - This file is influenced by the stl_config.h file delivered with egcs.
135 - Added "Include/auto_ptr.hxx" which contains an implementation of the
136 STL auto_ptr class which is not provided in all STL implementations
137 and is needed to use the callback classes.
138 - Deleted fgLightUpdate() which was just a wrapper to call
140 - Modified fg_init.cxx to register two method callbacks in place of the
141 old wrapper functions.
142 - The new classes in libmisc.tgz define a stream interface into zlib.
143 I've put these in a new directory, Lib/Misc. Feel free to rename it
144 to something more appropriate. However you'll have to change the
145 include directives in all the other files. Additionally you'll have
146 add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
148 The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
149 test so I've included the required changes in config.tgz.
151 There are a fair few changes to Simulator/Objects as I've moved
152 things around. Loading tiles is quicker but thats not where the delay
153 is. Tile loading takes a few tenths of a second per file on a P200
154 but it seems to be the post-processing that leads to a noticeable
155 blip in framerate. I suppose its time to start profiling to see where
158 I've included a brief description of each archives contents.
163 C++ stream interface into zlib.
164 Taken from zlib-1.1.3/contrib/iostream/.
165 Minor mods for STL compatibility.
166 There's no copyright associated with these so I assume they're
171 FlightGear input stream using gz_ifstream. Tries to open the
172 given filename. If that fails then filename is examined and a
173 ".gz" suffix is removed or appended and that file is opened.
176 A simple timer for benchmarking. Not used in production code.
177 Taken from the Blitz++ project. Covered by GPL.
181 Some simple string manipulation routines.
184 Load airports database using fgstream.
185 Changed fgAIRPORTS to use set<> instead of map<>.
186 Added bool fgAIRPORTS::search() as a neater way doing the lookup.
187 Returns true if found.
190 Modified fgStarsInit() to load stars database using fgstream.
193 Modified fgObjLoad() to use fgstream.
194 Modified fgMATERIAL_MGR::load_lib() to use fgstream.
195 Many changes to fgMATERIAL.
196 Some changes to fgFRAGMENT but I forget what!
199 * Stars added in 8 stages as sky gets darker for a smoother more realistic
201 * rewrote star loader to significantly improve load times.
202 * Tweaked sky brightness and dawn/dusk colors.
203 * Fixed a small problem with moon rendering.
204 * Fog color tries to track the sky color at the center of view in sunrise
205 and sunset situations.
206 * Optimizations from Norman Vine
207 * Code fixes and tweaks from Charlie Hotchkiss.
208 * Added an --enable/disable-sound option.
209 * Added a pause key "p"
210 * Added command line options to specify initial position and orientation.
211 * Added command line option to start in paused or unpaused state.
215 * Various HUD intensities so you can find something that is readable for the
216 current conditions and lighting.
217 * Tie visibility to far clip plane & view frustum culling so reducting
218 visibility can increase frame rates by increasing what is culled.
219 * Fixed stupid bug with misplaced initial position.
220 * Hopefully fixed a bug when parsing system.fgfsrc on windoze.
223 * HUD updates from Charlie Hotchkiss (ladder number rotate w/ ladder, control
224 position indicators are back)
225 * Only draw the PUI cursor if Mesa/Glide/Fullscreen.
227 * Calculate the model view transformation matrix once per tile per iteration.
228 Then glLoadMatrixd() it for each fragment rather than calling push(),
230 * Added a basic splash screen.
231 * Added support for switching between fullscreen and window mode for
233 * added an enable/disable splash screen option
234 * added an enable/disable intro music option
235 * added an enable/disable instrument panel option
236 * added an enable/disable mouse pointer option
237 * Ground collision detection. You can now land or test for collision with
239 * Converted angle of attack scale into a radio altimeter.
242 * Managment of multiple textures
243 * Incorporated Friedemann Reinhard's initial panel code.
244 * Fog mode is now GL_FOG_EXP2 instead of GL_FOG_LINEAR
245 * Build the non-shared pieces of the FG sim as static libs.
248 * Incorporated Steve Baker's PUI user interface library written
249 entirely on top of OpenGL
250 * Incorporated Steve Baker's Audio library which currently only
251 supports Linux, but a win32 port is very close to being done.
252 * Sort object fragments by material property before rendering. This
253 will be a big help to performance when we start including objects
254 with a wide variety of material properties and textures.
255 * Overlapped scenery tiles to reduce the chance of an occasional
256 floating point precission induced gaps.
257 * Fixed a bug in zlib exposed by Borland Win32 compiler.
258 * Impose a maximum triangle area during scenery generation so even
259 very flat areas will get split into a few smaller sub triangles.
260 * Fine grained (fragment level) view frustum culling.
261 * view transformation optimizations -- Norman Vine.
262 * Fixed polygon winding problem in scenery generation, so all
263 tri-strips are wound counter clockwise (opengl default).
266 * Course (per tile) view frustum culling.
267 * Added a command line option to specify --fg-root which will override
269 * Hard coded default locations for FG_ROOT for situations when nothing
270 is specified. Unix = /usr/local/lib/FlightGear Win32 = \FlightGear
271 * Restructured the command line processing code so that it can process
272 these sames comands (one per line) out of a config file.
273 * Added a command line option to specify field of view. This is
274 adjustable at run time using "X / x". Supporting code contributed
278 * Complete C++ re-write of the HUD section.
279 * Miscellaneous bug fixes and tweaks.
282 * Added an option to enable/disable wireframe rendering.
283 * Added an option to enable/disable fog/haze.
284 * Added an option to enable/disable sky blending.
285 * Added an option to select smooth/flat polygon shading.
286 * Added an option to enable full-screen mode.
287 * Added a visual frame rate counter on the HUD. (Contributed by Durk Talsma)
288 * Autopilot updates (Jeff Goeke-Smith)
289 * Added an option to control the number of neighboring tiles that are drawn
292 * Fixed a horible bug that cause the time to be *WAY* off when
293 compiling with the CygWin32 compiler.
294 * Wrap up zlib so we can conditionally compile back in normal behavior
295 on systems that have trouble building zlib.
296 * Minor adjustment to texture coordinate generation to reduce texture
298 * Added a command line option to enable/disable texture maps
299 * Minor transformation adjustments to try to keep scenery tiles closer
300 to (0, 0, 0) GLfloats run out of precision at the distances we need
301 to model the earth, but we can do a bunch of pre-transformations
302 using double floats and then cast to GLfloat once everything is
303 close in where we have less precision problems.
304 * command line option to set starting position by airport ID
305 * Cleaned up initialization sequence to eliminate interdependencies
306 between sun position, lighting, and view position. This creates a
307 valid single pass initialization path.
308 * use already calculated LaRCsim values to create the roll/pitch/yaw
309 transformation matrix
312 * material properties bug fixed when rendering terrain.
313 * bug in sky color generation fixed.
314 * bug in fog color generation fixed.
315 * zlib on the fly decompression/compression support.
316 * more code reorganization and clean ups.
317 * a fixed up 30 arcsec DEM file preprocessor. World wide DEM's are
318 available in this format.
321 * Simple autopilot heading hold contributed by
322 Jeff Goeke-Smith <jgoeke@voyager.net>
323 * More code reorganization and clean ups.
326 * Many autoconf cleanups and tweaks
327 * make and make install work in unix
328 * make works for cygnus win32 (but not install yet)
329 * make dist now works
330 * added the Tools directory into the main source tree
333 * Gnu automake/autoconf/libtool make system
334 * Initial texture support
