Thanks for the detailed explanation. It's very helpful.

So if I want to emulate OpenGL's view parameters in a raytracer (which is my
goal here), using the current camera I can get the parameters needed to create
a View matrix, and the Model matrix would just be a given node's "LocalToWorld"
matrix (as given by osg::computeLocalToWorld() with the node's path in a
NodeVisitor, for example)? Does that sound right?
Thanks for your help,
J-S
