I have been Google'n how to code a simple cut extrusion and have not found anything good or remotely what I am looking for. Perhaps "cut" is the wrong word?
Anyway, I have created a modeler to draw extruded walls both angular and curved. Now I would like to be able to "cut" a hole in these walls for door ways and windows and the like. I have some colision detection code already but I am really at a loss to know where to begin coding a negative or "cut" extrusion.
Does anyone have any links or resources??
