摘要
首先讨论了Bézier曲面及其性质、作为相邻的Bézier曲面片在拼接时边界处容易引起连续性和光顺性的问题,同时指出在实际应用中的一些复杂曲面很难用一片Bézier曲面来构造.针对这个问题,阐述了几种不同的连续和光顺拼接条件,以供在实际应用中根据要求来选择不同的约束条件.
The Bézier surface and its properties are discussed first.When Bézier surfaces are pieced together there is often a problem with the continuity and smoothness at their edges.At the same time,some complicated surfaces in actual application can not be configured with singular surface.In order to solve this problem,several continuous and smoothing conditions are described for their piecing together,so that they can be reasonably chosen in actual application.
