摘要
利用二元B样条的积分定义方法,构造其M(M≥2)尺度的加细方程.所得结果可概括现有的二元Box样条和最小支集的二元B样条的细分方法.
The present paper deals with the bivariate Bspline functions with integral definition on uniform typeⅠ triangulation and typeⅡ triangulation, and obtain the Mband refinement equations for any integer M(M≥2). The result in this paper can sum up the subdivision of bivariate Box splines and bivariate Bsplines with the minimal support. Furthermore, our method is simple and easy to be generalized.
