Hi Robert (and all) -- I want to get the view matrix, projection matrix, and viewport from the current slave Camera in a multi-display environment, and I want to get them from a cull callback (which could be buried beneath a HUD Camera or post-render processing Camera).
I think this is what I want to call: CullVisitor::getRenderStage(); I can see from the code that it returns the "root" RenderStage. But what exactly is that? Is it the RenderStage associated with the slave Camera? Or with the top-level osgViewer::Viewer's "master" Camera that drives the slaves? Thanks for any info. -- -Paul
