ABSTRACT:
A solid modeling method for modeling solids which include free-form surfaces calculates intersecting portions of two solids and storing calculated results as first data, stores free-form shapes of the two solids as second data, approximates free-form surface portions of the two solids by polyhedrons so as to describe the two solids in a form of polyhedrons, obtains a union, a difference or an intersection of the two solids by carrying out set operations on the polyhedrons, and returns the polyhedrons obtained by the set operations into solids including free-form surfaces based on the stored first and second data.
