|
* Some initial "GameGLUT" support contributed by Gary R. Van Sickle
|
|
(tiberius@braemarinc.com)
|
|
* Tracked down and eliminated some memory access type bugs that were
|
|
causing segfaults on some platforms, with some compilers using various
|
|
optimization flags.
|
|
* Assorted code optimizations submitted by Norman Vine.
|
|
* Renamed fg -> fgfs
|
|
* Shuffled files.
|
|
- Created a new directory Simulator/Airports/ to handle airport data
|
|
specific tasks
|
|
- Created Simulator/Object/ to handle basic rendering objects
|
|
* Panel code update from Friedemann Reinhard (use --enable-panel to activate)
|
|
* Contributions from Bernie Bright
|
|
- Created some new classes to enable pointers-to-functions and
|
|
pointers-to-class-methods to be treated like objects. These objects
|
|
can be registered with fgEVENT_MGR.
|
|
- File "Include/fg_callback.hxx" contains the callback class defns.
|
|
- Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
|
|
some minor tweaks to STL usage.
|
|
- Added file "Include/fg_stl_config.h" to deal with STL portability
|
|
issues. Added an initial config for egcs (and probably gcc-2.8.x).
|
|
Don't have access to Visual C++ so I've left that for someone else.
|
|
- This file is influenced by the stl_config.h file delivered with egcs.
|
|
- Added "Include/auto_ptr.hxx" which contains an implementation of the
|
|
STL auto_ptr class which is not provided in all STL implementations
|
|
and is needed to use the callback classes.
|
|
- Deleted fgLightUpdate() which was just a wrapper to call
|
|
fgLIGHT::Update().
|
|
- Modified fg_init.cxx to register two method callbacks in place of the
|
|
old wrapper functions.
|
|
- The new classes in libmisc.tgz define a stream interface into zlib.
|
|
I've put these in a new directory, Lib/Misc. Feel free to rename it
|
|
to something more appropriate. However you'll have to change the
|
|
include directives in all the other files. Additionally you'll have
|
|
add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
|
|
|
|
The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
|
|
test so I've included the required changes in config.tgz.
|
|
|
|
There are a fair few changes to Simulator/Objects as I've moved
|
|
things around. Loading tiles is quicker but thats not where the delay
|
|
is. Tile loading takes a few tenths of a second per file on a P200
|
|
but it seems to be the post-processing that leads to a noticeable
|
|
blip in framerate. I suppose its time to start profiling to see where
|
|
the delays are.
|
|
|
|
I've included a brief description of each archives contents.
|
|
|
|
Lib/Misc/
|
|
zfstream.cxx
|
|
zfstream.hxx
|
|
C++ stream interface into zlib.
|
|
Taken from zlib-1.1.3/contrib/iostream/.
|
|
Minor mods for STL compatibility.
|
|
There's no copyright associated with these so I assume they're
|
|
covered by zlib's.
|
|
|
|
fgstream.cxx
|
|
fgstream.hxx
|
|
FlightGear input stream using gz_ifstream. Tries to open the
|
|
given filename. If that fails then filename is examined and a
|
|
".gz" suffix is removed or appended and that file is opened.
|
|
|
|
stopwatch.hxx
|
|
A simple timer for benchmarking. Not used in production code.
|
|
Taken from the Blitz++ project. Covered by GPL.
|
|
|
|
strutils.cxx
|
|
strutils.hxx
|
|
Some simple string manipulation routines.
|
|
|
|
Simulator/Airports/
|
|
Load airports database using fgstream.
|
|
Changed fgAIRPORTS to use set<> instead of map<>.
|
|
Added bool fgAIRPORTS::search() as a neater way doing the lookup.
|
|
Returns true if found.
|
|
|
|
Simulator/Astro/
|
|
Modified fgStarsInit() to load stars database using fgstream.
|
|
|
|
Simulator/Objects/
|
|
Modified fgObjLoad() to use fgstream.
|
|
Modified fgMATERIAL_MGR::load_lib() to use fgstream.
|
|
Many changes to fgMATERIAL.
|
|
Some changes to fgFRAGMENT but I forget what!
|
|
|
|
New in 0.52
|
|
* Stars added in 8 stages as sky gets darker for a smoother more realistic
|
|
transition.
|
|
* rewrote star loader to significantly improve load times.
|
|
* Tweaked sky brightness and dawn/dusk colors.
|
|
* Fixed a small problem with moon rendering.
|
|
* Fog color tries to track the sky color at the center of view in sunrise
|
|
and sunset situations.
|
|
* Optimizations from Norman Vine
|
|
* Code fixes and tweaks from Charlie Hotchkiss.
|
|
* Added an --enable/disable-sound option.
|
|

|
* Added command line option to start in paused or unpaused state.
|
|
|
|
New in 0.51
|
|
* Translucent menus
|
|
* Various HUD intensities so you can find something that is readable for the
|
|
current conditions and lighting.
|
|
* Tie visibility to far clip plane & view frustum culling so reducting
|
|
visibility can increase frame rates by increasing what is culled.
|
|
* Fixed stupid bug with misplaced initial position.
|
|
* Hopefully fixed a bug when parsing system.fgfsrc on windoze.
|
|
|
|
New in 0.50
|
|
* HUD updates from Charlie Hotchkiss (ladder number rotate w/ ladder, control
|
|
position indicators are back)
|
|
* Only draw the PUI cursor if Mesa/Glide/Fullscreen.
|
|
* Added mipmapping.
|
|
* Calculate the model view transformation matrix once per tile per iteration.
|
|
Then glLoadMatrixd() it for each fragment rather than calling push(),
|
|
translate(), pop().
|
|
* Added a basic splash screen.
|
|
* Added support for switching between fullscreen and window mode for
|
|
Mesa/3dfx/glide.
|
|
* added an enable/disable splash screen option
|
|
* added an enable/disable intro music option
|
|
* added an enable/disable instrument panel option

|
|
|
|
New in 0.49
|
|
* Managment of multiple textures
|
|

* Build the non-shared pieces of the FG sim as static libs.
|
|
|
|
New in 0.48
|
|
* Incorporated Steve Baker's PUI user interface library written
|
|
entirely on top of OpenGL
|
|
* Incorporated Steve Baker's Audio library which currently only
|
|
supports Linux, but a win32 port is very close to being done.
|
|
* Sort object fragments by material property before rendering. This
|
|
will be a big help to performance when we start including objects
|
|
with a wide variety of material properties and textures.
|
|
* Overlapped scenery tiles to reduce the chance of an occasional
|
|
floating point precission induced gaps.
|
|
* Fixed a bug in zlib exposed by Borland Win32 compiler.
|
|
* Impose a maximum triangle area during scenery generation so even
|
|
very flat areas will get split into a few smaller sub triangles.
|
|
* Fine grained (fragment level) view frustum culling.
|
|
* view transformation optimizations -- Norman Vine.
|
|
* Fixed polygon winding problem in scenery generation, so all
|
|
tri-strips are wound counter clockwise (opengl default).
|
|
|
|
New in 0.47
|
|
* Course (per tile) view frustum culling.
|
|
* Added a command line option to specify --fg-root which will override
|
|
$FG_ROOT
|
|
* Hard coded default locations for FG_ROOT for situations when nothing
|
|
is specified. Unix = /usr/local/lib/FlightGear Win32 = \FlightGear
|
|
* Restructured the command line processing code so that it can process
|
|
these sames comands (one per line) out of a config file.
|
|
* Added a command line option to specify field of view. This is
|
|
adjustable at run time using "X / x". Supporting code contributed
|
|
by Norman Vine.
|
|
|
|

|
New in 0.44:
|
|
* Fixed a horible bug that cause the time to be *WAY* off when
|
|
compiling with the CygWin32 compiler.
|
|
* Wrap up zlib so we can conditionally compile back in normal behavior
|
|
on systems that have trouble building zlib.
|
|
* Minor adjustment to texture coordinate generation to reduce texture
|
|
swimming.
|
|
* Added a command line option to enable/disable texture maps
|
|
* Minor transformation adjustments to try to keep scenery tiles closer
|
|
to (0, 0, 0) GLfloats run out of precision at the distances we need
|
|
to model the earth, but we can do a bunch of pre-transformations
|
|
using double floats and then cast to GLfloat once everything is
|
|
close in where we have less precision problems.
|
|
* command line option to set starting position by airport ID
|
|
* Cleaned up initialization sequence to eliminate interdependencies
|
|
between sun position, lighting, and view position. This creates a
|
|
valid single pass initialization path.
|
|
* use already calculated LaRCsim values to create the roll/pitch/yaw
|
|
transformation matrix
|
