摘要
A system for topology directed subdivision of a pair of surfaces to identify intersecting portions thereof includes the steps of obtaining a pair of surfaces from a main pool of surface representations and performing a mutual point exclusion test to determine if the surfaces may have an intersection. For those pairs of surfaces possibly having an intersection, the transversality of the surface is checked. If tranversal, the intersection set is computed. For those pairs which are not transversal, recursive subdivision is performed until transversality is established or until a flatness criteria is met. A parallel processing system including a master processor and a plurality of slave processors performs the subdivision operation on the surfaces in a parallel fashion.
