The fbx plugin won't compile using gcc 4.3.2. I made the following
minor changes:
1. WriterNodeVisitor.cpp needed limits.h added to the headers.
2. gcc does not allow structures to be defined inside of functions, so
I moved the definition of PolygonRef out of the function to a global
scope (right above the function readMesh).
I also removed a bunch of embedded carriage returns
- missing copy attribute _referenceFrame in ClipNode in copy constructor
- checked iterators against the end in osgText
- close codec context in ffmpeg plugin to avoid memory leak
"
"enable thread locking in libavcodec
This is required for a multithreaded application using ffmpeg from
another thread."
"Prevent the audio from videos from hanging on exit if they are paused.
The video decoder already has similar logic."
"Add a way to retrieve the creation time for MPEG-4 files."
"fmpeg, improve wait for close logic
Both audio and video destructors have been succesfully using the logic,
if(isRunning())
{
m_exit = true;
join();
}
since it was introduced,
but the close routines are using,
m_exit = true;
if(isRunning() && waitForThreadToExit)
{
while(isRunning()) { OpenThreads::Thread::YieldCurrentThread(); }
}
which not only is it doing an unnecessary busy wait, but it doesn't
guaranteed that the other thread has terminated, just that it has
progressed far enough that OpenThreads has set the thread status as
not running. Like the destructor set the m_exit after checking
isRunning() to avoid the race condition of not getting to join()
because the thread was running, but isRunning() returns false.
Now that FFmpeg*close is fixed, call it from the destructor as well
to have that code in only one location."
osgViewer behaves smarter, when the computer will reboot or shutdown. In
older versions the reboot/shutdown got cancelled by GraphicsWindowCocoa,
now it behaves more system conform.
"
seems that the number of current active texture is wrong. It's because
of the line in Texture::TextureObjectSet::flushDeletedTextureObjects
_parent->getNumberActiveTextureObjects() += numDeleted;"
about the Observer header:
/home/cubicool/local/include/osg/Observer: In copy constructor
?osg::ObserverSet::ObserverSet(const osg::ObserverSet&)?:
/home/cubicool/local/include/osg/Observer:66: warning: base class ?class
osg::Referenced? should be explicitly initialized in the copy
constructor
I've been fixing this by hand by using the attached Observer header; it
does exactly what the warning requests. Purely cosmetic, I believe, but
other than that OSG seems to compile w/ -W -Wall just fine."
no PixelBufferObject 00000000, 00000000 pbo=00000000
It's kind of annoying since there is nothing actually wrong. The message is generated from TextureRectangle::applyTexImage_subload when it fails to create a pbo, even if the Image object is not even requesting to use a pbo. This message is not generated by all the other code in TextureRectangle.cpp & Texture.cpp that also attempts to create pbo's. I've modified TextureRectangle.cpp to remove this message, so it is at least consistent with the other code."
uncovered what looks like a type in the "src\osgPlugins\dae\
daeRMaterials.cpp" file. Line 1094 reads:
^^^
parameters.filter_min = getFilterMode(sampler->getMagfilter()->
getValue(), false);
whereas it should read
^^^
parameters.filter_mag = getFilterMode(sampler->getMagfilter()->
getValue(), false);

Out application has the ability to switch to different types of terrains on the fly. This problem only exists in this type of situation.
The TXPArchive is held by the ReadWriterTXP class. When the TXPNode, which is the top level node, is released from memory, the archive associated to that TXPNode is also released. The issue is that the reference count on the TXPArchive never gets to zero.
The reason why the reference count never gets to zero is because the TXPParse, which is owned by the TXPArchive, stores a ref_ptr to the TXPArchive. You can then see why this becomes a problem. The TXPParser's ref_ptr cannot be unreferenced since the TXPArchive has not released the TXPParser.
Since the TXPParser is fully contained within the TXPArchive, I don't see the reason to have the TXPParser have a ref_ptr to the TXPArchive. I've made this change locally and have had no problems and our memory leak has been fixed.

"changed the CmakeFiles for OpenThreads and the
osg-frameworks, so they are versioned by OPENSCENEGRAPH_SOVERSION. "
And from a later email:
"Attached you'll find a fixed version of ModulInstall.cmake. Hopefully it
works for old CMake-versions. I removed the offending line, and the
compile went fine on my end."
short oit. This rendering technique is also known as depth peeling.
Attached is the example that makes depth peeling work with the fixed function
pipeline. Ok, this is 'old fashioned' but required for our use case that
still has to work on older UNIX OpenGL implementations as well as together
with a whole existing application making use of the fixed function pipeline.
I can imagine to add support for shaders when we have that shader composition
framework where we can add a second depth test in a generic way.
This does *not* implement the dual depth peeling described in a paper from the
ETH Zurich.
This example could serve as a test case for the feature that you can on the
fly remove pre render cameras that you made work a few time ago.
It is also a test case for the new TraversalOrderBin that is used to composite
the depth layers in the correct blend order.
This example also stresses your new texture object cache since you can change
some parameters for the oit implementation at runtime.
You can just load any model with osgoit and see how it works.
Use the usual help key to see what you can change.
There is already an osgdepthpeeling example that I could not really make sense
of up to now. So I just made something new without touching what I do not
understand."
