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.

cbc43841e1 From Roland Smeenk, "this submission adds a "Fast Drawable" line to the camera scene statistics.
It shows the total number of sorted and unsorted drawables that use the fastpath for rendering."

7c38643a77 From Tim Moore, "I noticed that the "Materials" statistic in the camera scene stats display seemed to be identical to the number of drawables. In fact, it displays the nummat member of osgUtil::Statistics, but that variable has nothing to do with materials. nummat tracks the number of matrices associated with Drawable objects in a RenderBin; as I understand it, Drawables pretty much always have a model-view matrix tied to them in RenderBins, so this statistic doesn't seem very useful. So, I added statistics for the number of StateGraph objects in RenderBins and also for the number of Drawables in the "fine grain ordering" of RenderBins. The latter corresponds to the number of Drawables in the scene that are sorted by some criteria other than graphics state; usually that is distance for semi-transparent objects, though it could be traversal order. These two statistics give an idea of the number of graphic state changes happening in a visible scene: each StateGraph implies a state change, and there could be a change for each sorted object too. You can also subtract the number of sorted Drawables from the total number of Drawables and get an idea of how many Drawables are being drawn for each StateGraph.

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

aa69137fb8 Added collateReferencesToDependentCameras() and clearReferencesToDependentCameras() methods into RenderStage and SceneView, and use
of these methods in src/osgViewer/Renderer.cpp to make sure that the draw thread keeps references to all in scene graph Cameras
that are being used by the drawing threads, to keep the Camera's alive even when the main thread removes these Cameras from the scene graph.

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.
