Abstract:
A three-dimensional shape data processing apparatus that measures a length of a path on a surface of a three-dimensional shape represented by three-dimensional shape data, comprising:a point acceptance section for accepting input of at least four points that designates the path on the surface of the three-dimensional shape;a grouping section for grouping the points that have been accepted by the point acceptance section to form groups, each of which includes three accepted points, wherein two accepted points in one group are also included in another group;a first length obtaining section for obtaining each first length that is a length between two adjacent accepted points of three accepted points in one of the groups along a line of intersection of a plane including the three accepted points and the surface of the three-dimensional shape for each of the groups;a second length obtaining section for obtaining each second length that is a length between two accepted points commonly included in two of the groups along the path that has been designated by the point acceptance section according to first lengths that have been obtained by the first length obtaining section.
