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