## Subject: **Clipping 3D Triangle by Convex Polyhedron**

Hi,

I have a (hopefully) quite straightforward problem that I am having

trouble finding a solution to. I need to be able to clip a 3D triangle

by a 3D convex Polyhedron (which will always be an extruded triangle

itself into 3 dimensions).

At first I thought that I could just work out where each line of the

triangle intersected with the polyhedron and reduce the triangle in

this way but the more I have thought about it, the more I see that this

will not always work (e.g. if intersection occurs in the middle of the

triangle with and I need a more definite algorithm for this.

Any ideas?

Thanks,

Mark.
