Hi,
I am new to OpenGL and am trying to render a scene (off screen) to a frame buffer. In particular I have a number of polygons, each lying in a different z-plane. However the vertices in adjacent polygons are not connected, i.e. I have a plurality of polygons and not a polyhedral mesh (see attachement: Structure.jpeg). The polygons form a polyhedron, which may be convex or concave.
What I need to do is to write a binary mask which only assigns true for all pixels which lie inside of the polyhedron, all other pixels remain false. For this I probably need to use a stencil buffer (?).
This is not a homework question.
Any help would be much appreciated
Thanks
Mark
