摘要 基于24(Δ)的B样条基函数Fourier变换形式的加细方程,利用Fourier逆变换及对4个参变量取值的讨论,得到了三角形网格规则点的多进制细分掩模计算方法,并证明了每步细分过程中,在一个三角形上生成的所有新点为围绕此三角形的一层三角形环的所有顶点的线性组合. The calculational methods for multi-band subdivision masks of regular vertices of triangular mesh were derived from the Fourier transform refinement equation of the B-spline base of S24 (A) via the inverse Fourier transformation and valuation of four parameters. It was also confirmed that every new generated point in a triangle is the linear combination of the vertices of the first triangle ring around the triangle.
