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

239 * make dist now works
240 * added the Tools directory into the main source tree
243 * Gnu automake/autoconf/libtool make system
244 * Initial texture support
