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