Hello, I'm working on a CSG ray tracer but I've run into a bit of a snag. I have a CSG tree built using three operations: Union (|), Intersection (&) and Difference (-). Now I'm trying to figure out how to determine the intersections with the various objects descibed in the tree. Does anyone have such an algorithm they are willing to share? Pointers toward such an algorithm? Thanks, Paul Lalonde Paul A.
