C-Coons曲面片及其性质

C-Coons Patch and Its Property

摘要: 讨论由C-Hermite函数构造的C-Coons曲面片.C-Coons曲面是双三次Coons曲面的推广,它的形状调整还依赖于参数α,β.当α,β→0时,Coons曲面的极限是双三次Coons曲面.

Abstract: A new type Coons patch called C-Coons patch constructed by C-Hermite blending functions is discussed. C-Coons patch presents an extension of bicubic Coons patch. Its shape depends on two parameters α, β and the limiting case for α, β→0 is bicubic Coons patch.
