2 * Stars added in 8 stages as sky gets darker for a smoother more realistic
4 * rewrote star loader to significantly improve load times.
5 * Tweaked sky brightness and dawn/dusk colors.
6 * Fixed a small problem with moon rendering.
7 * Fog color tries to track the sky color at the center of view in sunrise
9 * Optimizations from Norman Vine
10 * Code fixes and tweaks from Charlie Hotchkiss.
11 * Added an --enable/disable-sound option.
12 * Added a pause key "p"
13 * Added command line options to specify initial position and orientation.
14 * Added command line option to start in paused or unpaused state.
18 * Various HUD intensities so you can find something that is readable for the
19 current conditions and lighting.
20 * Tie visibility to far clip plane & view frustum culling so reducting
21 visibility can increase frame rates by increasing what is culled.
22 * Fixed stupid bug with misplaced initial position.
23 * Hopefully fixed a bug when parsing system.fgfsrc on windoze.
26 * HUD updates from Charlie Hotchkiss (ladder number rotate w/ ladder, control
27 position indicators are back)
28 * Only draw the PUI cursor if Mesa/Glide/Fullscreen.
30 * Calculate the model view transformation matrix once per tile per iteration.
31 Then glLoadMatrixd() it for each fragment rather than calling push(),
33 * Added a basic splash screen.
34 * Added support for switching between fullscreen and window mode for
36 * added an enable/disable splash screen option
37 * added an enable/disable intro music option
38 * added an enable/disable instrument panel option
39 * added an enable/disable mouse pointer option
40 * Ground collision detection. You can now land or test for collision with
42 * Converted angle of attack scale into a radio altimeter.
45 * Managment of multiple textures
46 * Incorporated Friedemann Reinhard's initial panel code.
47 * Fog mode is now GL_FOG_EXP2 instead of GL_FOG_LINEAR
48 * Build the non-shared pieces of the FG sim as static libs.
51 * Incorporated Steve Baker's PUI user interface library written
52 entirely on top of OpenGL
53 * Incorporated Steve Baker's Audio library which currently only
54 supports Linux, but a win32 port is very close to being done.
55 * Sort object fragments by material property before rendering. This
56 will be a big help to performance when we start including objects
57 with a wide variety of material properties and textures.
58 * Overlapped scenery tiles to reduce the chance of an occasional
59 floating point precission induced gaps.
60 * Fixed a bug in zlib exposed by Borland Win32 compiler.
61 * Impose a maximum triangle area during scenery generation so even
62 very flat areas will get split into a few smaller sub triangles.
63 * Fine grained (fragment level) view frustum culling.
64 * view transformation optimizations -- Norman Vine.
65 * Fixed polygon winding problem in scenery generation, so all
66 tri-strips are wound counter clockwise (opengl default).
69 * Course (per tile) view frustum culling.
70 * Added a command line option to specify --fg-root which will override
72 * Hard coded default locations for FG_ROOT for situations when nothing
73 is specified. Unix = /usr/local/lib/FlightGear Win32 = \FlightGear
74 * Restructured the command line processing code so that it can process
75 these sames comands (one per line) out of a config file.
76 * Added a command line option to specify field of view. This is
77 adjustable at run time using "X / x". Supporting code contributed
81 * Complete C++ re-write of the HUD section.
82 * Miscellaneous bug fixes and tweaks.
85 * Added an option to enable/disable wireframe rendering.
86 * Added an option to enable/disable fog/haze.
87 * Added an option to enable/disable sky blending.
88 * Added an option to select smooth/flat polygon shading.
89 * Added an option to enable full-screen mode.
90 * Added a visual frame rate counter on the HUD. (Contributed by Durk Talsma)
91 * Autopilot updates (Jeff Goeke-Smith)
92 * Added an option to control the number of neighboring tiles that are drawn
95 * Fixed a horible bug that cause the time to be *WAY* off when
96 compiling with the CygWin32 compiler.
97 * Wrap up zlib so we can conditionally compile back in normal behavior
98 on systems that have trouble building zlib.
99 * Minor adjustment to texture coordinate generation to reduce texture
101 * Added a command line option to enable/disable texture maps
102 * Minor transformation adjustments to try to keep scenery tiles closer
103 to (0, 0, 0) GLfloats run out of precision at the distances we need
104 to model the earth, but we can do a bunch of pre-transformations
105 using double floats and then cast to GLfloat once everything is
106 close in where we have less precision problems.
107 * command line option to set starting position by airport ID
108 * Cleaned up initialization sequence to eliminate interdependencies
109 between sun position, lighting, and view position. This creates a
110 valid single pass initialization path.
111 * use already calculated LaRCsim values to create the roll/pitch/yaw
112 transformation matrix
115 * material properties bug fixed when rendering terrain.
116 * bug in sky color generation fixed.
117 * bug in fog color generation fixed.
118 * zlib on the fly decompression/compression support.
119 * more code reorganization and clean ups.
120 * a fixed up 30 arcsec DEM file preprocessor. World wide DEM's are
121 available in this format.
124 * Simple autopilot heading hold contributed by
125 Jeff Goeke-Smith <jgoeke@voyager.net>
126 * More code reorganization and clean ups.
129 * Many autoconf cleanups and tweaks
130 * make and make install work in unix
131 * make works for cygnus win32 (but not install yet)
132 * make dist now works
133 * added the Tools directory into the main source tree
136 * Gnu automake/autoconf/libtool make system
137 * Initial texture support
