Abstract

Abstract: A class of blending functions is presented and the characteristics of the blenging functions are illustrates. Based on this class of blending functions, a class of mixed Coons patches with shape parameters is constructed. The constructed patch not only keeps good properties of Coons surfaces, but also can adjust its shape by changing the values of parameters. Furthermore, the conditions of smooth splice of mixed class Coons patch are also discussed. The examples illustrate the effectiveness of giving method.

Key words: mixed Coons patches, shape parameter, optimization, smooth splice

摘要： 给出了一组带形状参数[λ1]、[λ2]的混合函数，分析了该组函数的性质。基于这组带形状参数的混合函数，构造了一种带形状参数的混合Coons类曲面片。所构造的曲面不仅保持了Coons曲面的良好边界插值性质，而且可通过调控形状参数来改变曲面的内部形状。讨论了带形状参数的混合Coons类曲面片光滑拼接的条件，通过实例说明了方法的实用性。
