摘要

The aim of this research is to develop methods to rapidly create rough three dimensional shape models for free-formed objects. Such methods are useful for designing concept models of products and animation characters. Conventional para- metric surface modelling methods are too cumbersome for this aim. The basic representation of the shape in this approach is a triangular mesh (a polygon with triangular faces), thus it is easy to change the shape. The theory of "Welch-Witkin Approximations of Thin Plate Surfaces" is used to give surface characteristics to the mesh and makes it possible to ma- nipulate the triangular mesh as if it were a surface model.
