Let me take a crack at this; if I'm wrong, I'd like to
be publicly shamed so that the correct answer will be engraved into my
head.
My understanding is that Producer::Camera (and
CameraGroup) is/are excellent for multithreaded rendering (with the traversal in
a separate thread) and also for rendering to multiple displays (each with their
own graphics card). osg::CameraNode, on the other hand, is well-suited for
render-to-texture applications in which you'd like the offscreen rendering to be
automatically culled if the results are not needed for the final rendered
image.
