Abstract in different language: A new algorithm for image-space CSG rendering is presented, based on subtraction of convex objects in a specific sequence. The algorithm has been implemented on OpenGL PC graphics hardware, as well as SGI workstations. Advantages of the algorithm include simpler implementation, closer affinity to hardware copabilities and comparable performance to other image-space CSG algorithms. The new algorithm is described, and compared to previous algorithms, experimentally and theoretically. Some graphics hardware issues related to image-space CSG performance are also discussed.
