提出了一种构造插值Loop细分曲面的新方法。新方法是B样条渐进插值技术的推广。给定一个三角形网格M,其思想是迭代地更新M的顶点以生成一个新的控制网格,使得M的极限曲面插值M。对Loop细分曲面,证明了迭代过程是收敛的。因此,该方法定义明确。新方法兼具局部方法和全局方法的优点,即,它可以处理任何尺寸和任何拓扑的网格,同时生成忠实地类似于给定网格形状的平滑插值细分曲面。
A new method for constructing interpolating Loop subdivision surfaces is presented. The new method is an extension of the progressive interpolation technique for B-splines. Given a triangular meshM, the idea is to iteratively upgrade the vertices ofMto generate a new control meshsuch that limit surface ofinterpolatesM. It can be shown that the iterative process is convergent for Loop subdivision surfaces. Hence, the method is well-defined. The new method has the advantages of both a local method and a global method, i.e., it can handle meshes of any size and any topology while generating smooth interpolating subdivision surfaces that faithfully resemble the shape of the given meshes.
