| Abstract: | Based on the advantages of subdivision surface modeling and the importance of interpolating boundary curves in engineering surface, a new interpolating Catmull-clark subdivision by boundary sampling is proposed in this paper. First, Catmull-Clark subdivision scheme is introduced simply, and then in order to satisfy boundary condition, boundary sampling is proposed. At last the algorithm of interpolating Catmull-Clark subdivision is discussed detailedly. The feasibility and effectiveness of the algorithm is validated through an example. |
