Abstract
An shape data approximation method for reducing the amount of data with an adjacency relationship between a plurality of components maintained. The shape data is read, an adjacent region of the shape data is designated, a virtual surface and a virtual edge are created in the designated adjacent region, and each edge in the shape data is evaluated to determine a evaluation score. The evaluation score is based on a change in the shape of the adjacent region on the assumption that the virtual edge is removed. The edges are subjected to data sorting, and an edge having a low evaluation score is removed with high priority, and resulting approximate shape data is thus output.
