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

265 * added the Tools directory into the main source tree
268 * Gnu automake/autoconf/libtool make system
269 * Initial texture support
