PROBLEM TO BE SOLVED: To provide an n-dimensional geometric model storage and display device that can achieve a compact data size while maintaining sufficient display quality in a simultaneous wire and shading display.;SOLUTION: When a geometric model of an n-dimensional space is stored, vertex coordinates of polylines are stored in a polyline vertex coordinate table. A vertex coordinate of the vertex coordinates of the triangular meshes on a mesh boundary is replaced by a vertex coordinate of a polyline the most adjacent to the vertex coordinate, and the triangular mesh is stored in a triangular mesh vertex coordinate table. The polyline division number of the polyline corresponding to each polyline is stored in a polyline division number table. The division number of a mesh boundary corresponding to each polyline is stored in a mesh boundary division number table. When the n-dimensional geometric model is to be displayed, triangular meshes are first displayed, and the polylines are displayed by matching the polyline division with the division number of the mesh boundary.;COPYRIGHT: (C)2005,JPO&NCIPI
