摘要

The purpose of this study is to generate surface patches which are useful throughout the product-design-process using the three dimensional point data measured by commerically obtainable measuring instruments. Delaunay Triangulation is introduced to construct triangular mesh from the three dimensional measured points. pseudo normal vectors are calculated using triangular mesh in a very short time. Using pseudo normal vectors, product-designers are able to examine the designed surface patches precisely by shading or newly developed color striped shading. Then product-designers are able to select the point data which correspond to the filleted or characteristic part, and generate the surface patches which are easy to manipulate for narrowing down to the final design. A golf club design-process from the measured points is shown as an actual example.
