fun, It may be an easier approach to create triangular surfaces and then cull the ones you don't need. Subdividing a trimmed triangular surface will produce all the quad surfaces from the untrimmed shape which, using data branching, can be easily split back up into tris. Then you can test all the tris against the original surface to cull any outside of it.
