SHAPE DATA GENERATION METHOD AND DEVICE

摘要

This shape data generation method includes processes that: set, with respect to a target shape which is a shape of a deformation target which is specified by image data, an input shape having a simple shape having the same topology as the target shape; specifies, from a plurality of vertices of the input shape, a first vertex which satisfies a prescribed condition including a condition of a normal having an intersection with the target shape; deforms the input shape such that the specified first vertex moves in the direction of the normal for the first vertex by a first distance which is shorter than the distance to the target shape; changes the post-deformation input shape to an input shape to be processed and executes the specification of the first vertex and the change of the input shape a prescribed number of iterations.
