Abstract: PROBLEM TO BE SOLVED: To obtain a set operation between three-dimensional objects by holding a parameter value at the endpoint node of each plane when a polyhedron is made and approximately calculating a parameter value on a point on a curved surface with the parameter value and a point projected on a plane. SOLUTION: Free-form surface data and point data are inputted (Step1), and a curved surface is made a polyhedron by using a device making the inputted free-form surface a polyhedron (Step2). When a plane (polygon) of a polyhedron existing in the neighborhood of the point is obtained (Step3) and is made a polyhedron, a parameter value is held at the endpoint node of each plane and, that is, the approximate parameter of the point is obtained from the parameter value of the polygon endpoint node (Step4). Further, a parameter value on the curved surface of the point is approximately calculated by using a device projecting a point onto a plane (Step5). Thus, since an interference line between free-form surfaces can be found, it is possible to perform a set operation between three-dimensional objects.
