Quicktime supports only files with 3/4-channels rgba-files and not 1/2-channels rgb-files.
This submission is from Tatsuhiro Nishioka, here's his original quote:
When FlightGear crashes, the error message
"GraphicsImportGetNaturalBounds failed" shows up. By adding printf
debug, I found the error was -8969: codecBadDataErr when loading a
gray-scaled (2 channels) rgba files even though the file can be loaded
with Gimp and osgViewer properly.
So I made an investigation on this problem and found an interesting
thing. This error occurs only when non-rgb files are loaded before rgb
files. The reason is that rgba files can be handled by both
osgdb_rgb.so and osgdb_qt.so, but the error happens only when
osgdb_qt.so try to load a gray-scaled rgba file.
When a program is about to load an rgba file, osgdb_rgb.so is loaded
and it handles the rgba file properly. In contrast, when a gray-scaled
rgb file is being loaded after a non-rgb file (say png) is already
loaded by osgdb_qt.so, osgdb_qt.so tries to load the file instead of
osgdb_rgb, which causes the error above.
Anyway, the bad thing is that QuickTime cannot handle gray-scaled rgb
files properly. The solution for this is not to let osgdb_qt handle
rgb files since osgdb_rgb can handle these properly.
"
This code will add two extra statistics options:
-Camera scene statistics, stats for the scene after culling (updated at 10 Hz)
-View scene statistics, stats for the complete scene (updated at 5 Hz)
Each camera and each view will expand the statistics to the right.
I also added the requests and objects to compile of the databasepager to the databasepager statistics.""
Attached is a change that is able to provide shared textures for the clamp and
the repeat case.
So this appears to be the best fix I guess ...
Also it additionaly shares the TexEnv StateAttribute in a whole ac3d model."
..\..\..\..\src\osgDB\Registry.cpp(910) : warning C4806: '==' : unsafe operation: no value of type 'bool' promoted to type 'osgDB::Registry::LoadStatus' can equal the given constant
A quick review of the code revealed a piece of code that was clearly wrong, possibly due to a copy-and-paste error.
"
The fix was to check whether glGetString( GL_VERSION ) returned a null pointer (Ref. svn diff below). The altered src/osg/GLExtensions.cpp is zipped and attached to this email."
"Soft shadow mapping is basically the same as hard shadow mapping beside that
it uses a different fragment shader.
So for me it makes sense that osgShadow::SoftShadowMap is derived from
osgShadow::ShadowMap, this makes it easier to maintain the two classes.
Additional SoftShadowMap also provides the same Debug methods as ShadowMap."
