Constructive Solid Geometry

By Alan Baylis 21/03/2003

To make a world editor or clean up existing world data we need to dabble in the art of constructive solid geometry (CSG) and to make a start I have put together this demo. The demo shows how to do csg addition between multiple convex brushes. The details of which can be found in the tutorial.
