| Research Abstract |
In style design system, tensor-product quadrilateral surfaces are used but it is difficult to connect them each other at arbitrary boundaries. Hence we have developed methods to represent free-form shapes with high-quality by a subdivision surface composed of a triangle mesh. We have proposed a method of anisotropic smoothing for measured data by using normalized discrete Laplacian, and a simplified Newton method for fitting a mesh with high quality and efficiently along with a method for determining boundary condition at sharp features to represent cross boundary curvature.
