人脸造型中的细分网格样条技术

A Splines Method in Refined Grid for Face Moulding

目前曲面造型用网格点上非均匀分划有理B样条,受网格点限制,在某些要更细微造型的地方要进行第二次的修改。本文对人脸造型给出细分网格样条方法,在要细微造型的眼角、嘴角等地设立细分网格,一次成型。由于B样条有局部支撑性,方法简单易行。

A splines method in refined grid points for face moulding is presented in this paper which can be used in the corner of the eyes and the corner of the mouth that need to know some details. At present, using NURBS(给出全称) surface methods it must be done by two times. Because of the local support of B-spline, the refined grid splines method is simple and easy to carry out by computers.
