Hi, Sorry to resurrect this old topic but I am stuck on the same problem (storing the model-view-projection matrix of the last frame in a uniform for each drawable of my scene).
I derived the NodeCallback class and cast the nodevisitor passed to its operator() to a CullVisitor. The said nodecall is then added to a Geode via the addCullCallback() method. However, the matrices I get seem off. For instance, when displaying my uniforms via gDebugger, it appears the coefficients of the CullVisitor::getModelViewMatrix() are quite different from the coefficients of the built-in uniform osg_ModelViewMatrix. For debugging purposes, all transforms (including the camera's) are kept unchanged across frames. What could possibly go wrong? I am using OSG-3.2.1-rc3 on Windows x64 (compiled with Visual Studio 2010). Any insight would be much appreciated. Cheers. :) ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=59837#59837 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
