It sounds like your interests in constructing complex 3D objects programmatically is very similar to what I am looking to do. That is why I got involved in implementing a CSG solution for jMonkey. I am hoping to utilize CSG as a tool for building an ‘architecture’ package that will understand buildings/rooms/walls/doors etc.
Please keep posting back to this thread so that we can all learn from your experiences. I am very new at all this and am very interested to see if CSG is a reasonable approach.
