摘要

针对T 样条曲面Bézier 提取中的参数域T 网格的Bézier 分片问题，提出了一种基于队列的参数域T 网格的Bézier 分片算法。该算法首先通过延伸T 型参数点对参数域网格进行切分，之后通过计算每个参数点所耦合的T 样条混合函数非零区域对参数域网格进一步切分。上述切分过程只需借助一个队列数组即可实现。通过实例测试，验证了本算法的有效性。

Abstract

Aiming at the problem of Bézier segmentation of T-mesh in parametric space

an algorithm based on queue was proposed. Firstly

T-mesh is segmented by the extension of T-vertices. Then a further segmentation is implmened by every nonzero region of blending function which is coupled to a vertex in T-mesh. An array of queue is used to realize the actual segmentation of the face in T-mesh. Some typical examples are illustrated to verify the validity of the algorithm at length.
