CADCAM,and simulation.After a short description of our CUBI 7 system (a 3D real-time Z-buffer system),and its CRISTAL module which increases RAY-TRACING computations, we present ourhardware project based on :-Parallel architecture for RAY-TRACING, special effects ; This module is alsouseful for pre-processing the image : (rotations, clipping, perspective transform... ).-A or Z-BUFFER which will be designed on VLSI chips polygon filling will be alsodesigned with pipe-lined chips."
