bada884342 From Pjotr Svetachov, "when you restart threading
with startThreading/stopThreading the _drawQueue and _availableQueue
are not reset properly. This can lead to a deadlock when threading is
started again. So before threading is started again the queues must be
reset. This deadlock is also reported earlier by someone else in here:

e4b1b6228d From Tim Moore, "This patch fixes a race condition in Renderer::ThreadSafeQueue that was causing some notifications of available SceneView objects to be missed. I saw a very noticeable performance problem (60 fps -> 8 fps) in DrawThreadPerContext mode in an osgEarth application before this patch. I had high hopes that this change might fix the much-discussed multiple GPU problem; no such luck, but I think the root cause of that is probably a similar threading issue." 2011-01-11 16:58:17 +00:00

68f37c4dcb From Tim More and Robert Osfield, implementation of ARB_timer_query based GPU timing stats syncronization.
Initial email from Tim : "I've implemented using a timestamp, available with ARB_timer_query and OpenGL 3.3, to gather GPU stats. This is nice because it can accurately fix the GPU draw time with respect to the other times on the stats graph, rather than having to estimate the wall time of the end of GPU drawing. This also prevents anomalies like the GPU phase starting before the draw phase..."
Changes to Tim's submission by Robert:  Removal of need for swap buffer callback in ViewerBase.cpp, by
integrating a osg::State::frameCompleted() method that does the stats timing collection.  Introduction of a
GraphicsContext::swapBuffersCallbackOrImplementation() method that calls the State::frameCompleted() and
the swap buffers callback or the swapImplementation as required.

c0e9fcbb67 From Tim Moore, "This contains a couple of fixes to support changing FrameBufferObject configurations on the fly; the user changes the camera attachments and calls Renderer::setCameraRequiresSetUp(). The major part of this submission is a comprehensive example of setting up floating point depth buffers. The user can change the near plane value and cycle through the available combinations of depth format and multisample buffer formats." 2010-04-19 11:43:06 +00:00

4d7b2edd4c Moved compile setup from osgViewer::ViewerBase into osgViewer::Renderer to
avoid threading issues associated with compile running in a parallel with 
update/cull on the first frame.

Also added automatic recompile when a new SceneData is applied to a View.
