ABSTRACT:
In the proposed geometric processing system geometry and space are partitioned into a plurality of subspaces by virtual partitioning lines passing characteristic points of the geometry and geometric sides. Pointers are respectively set for the characteristic points on the left and right side of each subspace. These two pointers set in one subspace point to each other. Each subspace is represented by such a pair of pointers. Based on the above-mentioned partition method, a plurality of subspaces are then adjacent to each characteristic point. Pointers for each characteristic point are grouped so that they correspond to each characteristic point on a one to one basis. This geometric processing system includes a data bse comprising data grouped in such a way. The propsed geometric/graphic data structure enables high-speed geometric processing for a wide range of applications including LSI/VLSI design.
