Ray casting with CSG tree

Question

I'm working a project in which I have to perform ray casting and use CSG trees. But I don't know how to use the CSG trees or implement it for this project. I can do the ray cast and give the final answer. My problem is really how to implement the tree and link it.

Did you mean CSG? (Constructive Solid Geometry?) – Adrian McCarthy Jun 23 '11 at 20:03 — Adrian McCarthy, Jun 23 '11 at 20:03
Yep, my bad.. I mean CSG (Constructive Solid Geometry) yes. – user812926 Jun 23 '11 at 20:45 — user812926, Jun 23 '11 at 20:45

The following PhD thesis details various CSG rendering techniques in OpenGL. Part of the thesis illustrates how CSG trees are constructed and simplified. A program (with full C++ source code) demonstrates the various algorithms mentioned in the thesis and will also give you an implementation of a CSG tree.
