摘要
充分利用可调控Catmull-C lark细分规则与均匀的Catmull-C lark细分规则的优点,提出了自适应细分方法。该方法简单,比传统的单一细分方法有更好的灵活性,通过适当调节控制因子,可使得曲面造型比较灵活。通过分析曲面上点的曲率来控制细分,可以在较低的细分次数下达到良好的曲面造型效果,为曲面造型提供了一个新的方法。
This paper proposed surfaces modeling with adaptive refinements which has more flexible than the traditional single subdivision scheme through propriety to adjust control genes and takes full advantages of the excellence of control Catmull-Calrk subdivision scheme and the excellence of uniform Catmull-Clark subdivision scheme. We can control subdivision times by analysis the point curvature in surfaces, so we get a well surfaces modeling scheme which can subdivided with lower times. This subdivision scheme provided a new method in surfaces modeling.
