论文摘要
Bezier参数贴片经常用于工程实践，尤其是在以机械设计为导向的CAD/CAM系统中。在许多情况下，四边形网格用于参数结构域的镶嵌。我们提出了对Bezier立方矩形贴片（BS-PATCH）的新修饰，该修饰基于以下要求，即对角线曲线必须为3度，而不是度6度，就像在Bezier贴片的情况下一样。提出了条件的理论推导，还提供了一些实验结果。 BS-PATCH对于应用不可接受的U-V结构域不同程度的不同程度的应用程序是方便的。
Bezier parametric patches are used in engineering practice quite often, especially in CAD/CAM systems oriented to mechanical design. In many cases quadrilateral meshes are used for tessellation of parameters domain. We propose a new modification of the Bezier cubic rectangular patch, the BS-patch, which is based on the requirement that diagonal curves must be of degree 3 instead of degree 6 as it is in the case of the Bezier patch. Theoretical derivation of conditions is presented and some experimental results as well. The BS-Patch is convenient for applications where for different tessellation of the u-v domain different degrees of diagonal curves are not acceptable.
