CURVED SURFACE GENERATION METHOD, PROGRAM, AND 3-DIMENSIONAL SHAPE PROCESSING DEVICE

摘要

A plurality of representative points are selected from a point group obtained as a result of shape measurement of an object. According to the positional relationship between the representative points and points existing around the representative points, a main curvature at each representative point is calculated. According to the main curvature at the representative point, a curvature line generated. By using the curvature line, a curved surface is generated.
