In the attached file (src/osgWrappers/deprecated-dotosg/osgParticle/IO_Particle.cpp) I have added a check for the existence of the drawable before writing it to the file.
"
- using m.getPerspective( fovy, tmp, tmp, tmp ) to get only FOV does not work.
The reason is that getPerspective is taking tmp as reference - thus all the three variables points to the same memory location. Then, zNear (third parameter) is used inside the method, while zNear content was spoiled by zFar that was written to the same place, resulting in fovy set to nan. I consider that it is the right of programmers to use 3 times tmp as parameter and I fixed the code in the method. I have done the same for getFrustum and getLookAt.
- I fixed makeFrustum to accept infinite zFar. (Some graphics techniques like shadow volumes require placing zFar to infinity to avoid visual artifacts.)"
Note from Robert Osfield, change the local near & far variable names to temp_near and temp_far MS Visual Studio has a record of using near and far names.
This problem caused because osgManipulator::Dragger uses matrices of top camera instead last
absolute Camera in NodePath.
I attached modified osgManipulator/Dragger.cpp file, where added code for finding last absolute
camera. With this changes draggers works in HUD.
Example for demonstrate this problem you can find in osg-users list [1].

attached. The problem was that the output files were not properly
setting the debug/release libs due to this cmake bug. What occurred was
the release lib was set in all configurations."
to download the texture object to graphics card.
Calling IncrementalCompileOperation::assignForceTextureDownloadGeometry() assigns a geometry
to the job.
changed extensions from .c to .cpp and got compiling as C files as part of the osg core library.
Updated and cleaned up the rest of the OSG to use the new internal GLU.
change was to use doubles for reading and writing matrices regardless of type of Matrix
being serialized.
Change does break backwards compatibility though, so code
path supporting original format has been left in for the
time being. However, this code is not reliable enough and
is over complicated compared to the simplified handling. Once
the new code has been bedded down for a while I'll remove this code block.
a discrepancy in getOrCreateObserverSet. For the atomic- and
mutex-codepaths the newly created observerset gets manually ref'ed, but
not in the codepath used when OPENTHREADS_ATOMIC_USE_MUTEX is defined. I
added the manual ref and tadaaa, the crash went away."
I also uderstand that there is a need to select system wide default method and have also modified DisplaySettings to contain swapMethod parameter. Swap method in Traits uses value set in DisplaySettings as default. Proper environment and command line args were added. Its possible to define default DeisplaySettings swap method in standard way via system flags or with comand line.
Env Vars:
OSG_SWAP_METHOD = DEFAULT | COPY | EXCHANGE
or Command Line:
--swap-method DEFAULT | COPY | EXCHANGE
I also added handling of WM_ERASEBKGND in GraphicsWindowWin32. It may be unneccessary but code should be safer this way than without handling it. I have placed a comment explaining the reason above the change.
Changes were made against today trunk.
PS. I tested only Windows code. I briefly checked X11 & Cocoa files but have not noticed SwapMethod to be used there.
