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