A system architecture for parallel geometric modelling

Methods to increase the performance of advanced CAD systems, especially of geometric modellers, by parallel processing are represented in this paper. First, the exploration of parallelism in geometric modellers and the organization of the parallel processing are shown. Apart from that, it is hinted at the great portion of time for accessing model data and handling its structure-information. In this context a functional unit for parallel handling of model accesses is sketched out. Finally, the hardware architecture is described
