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