Shape acquisition apparatus, target surface shape object manufacturing apparatus, target surface shape object manufacturing method, and program

摘要

The shape acquisition device is divided into a target surface curvature line acquisition unit for obtaining a plurality of maximum main curvature lines and a plurality of minimum main curvature lines on the formation target surface, and the formation target surface is divided by the maximum main curvature line and the minimum main curvature line. And an on-plane area obtaining unit that obtains data indicating the shape of the area on the corresponding plane.
