Shape analysis system, three-dimensional shape model difference detection system, similar shape search system, shape analysis method, and storage medium
Through comparison of electronic shape data for parts, the invention automatically detects a difference in shapes of products due to the design change, and/or searches for a product that is similar in shape. A shape analysis system comprises: an analysis tree node generator; a neighbor graph generator, for creating an edge between the nodes that are generated by the analysis tree node generator and that are geometrically adjacent, so as to produce a neighbor graph; and an analysis tree generator, for merging nodes in the neighbor graph that are generated by the neighbor graph generator and that are connected by the edge, for generating a new node in correlation with a 3d-shape that encloses patches included in the merged nodes and a shape analysis tree wherein the node acquired by merging is defined as a parent node and the other nodes, before being merged, are defined as child nodes.
