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.
