To understand the ideas behind managing the rendering It would
probably be easiest to just read up online one how to do such
rendering using OpenGL.  Topics to look into would be OpenGL, Stencil
Buffer Consutrctive Solid Geometry.

Perhaps members of the community have their favourite tutorials on this topic.

The OSG fully supports stencilling, controls on depth+color buffers,
shaders, controls for managing multi-pass rendering.  The osgreflect
example provide a very simple example of managing stencilling.
