Abstract
A method includes: an input step of inputting boundary surface informationon an object to a computer using the computer; a grid sampling step of determining cutting pointswhere the boundary surface cuts across edges of a predetermined rectangular parallelepiped gridand normal vectorsof the boundary surface at the cutting points, and storing them in a storage unit as primary data; a D-polyhedron data generation step of connecting adjacent cutting points with a line segment to form a triangle one by one for generating D-polyhedron dataconstituted of triangles only; and a V-polyhedron data generation step of generating V-polyhedron dataconstituted of intersections of a plurality of infinite planes passing through the cutting points and whose normals coincide with the normal vectors. Any one of the D-polyhedron data and the V-polyhedron data is generated from the primary data, and the other is generated as a dual.
