摘要

In reverse engineering, it is necessary to reconstruct surfaces from curves extracted from the cloud points in advance. A typical approach of such a technique is skinning, where serial section curves are provided to create a skinned surface. However, there is another type of requirement in which one or two directors incorporated with several generators are specified. The objective of this study is to propose a surface reconstruction technique for such a requirement. A sweeping technique based on coordinate transformation is proposed to generate section curves for various combinations of generators and directors. A skinning approach based on either interpolation, or fitting is then implemented to form a surface from. the section curves. Several examples are demonstrated to illustrate the feasibility of the proposed method for different combinations of generators and directors.
