如果还在为nurbs上找三角网格纠结的话为啥不用topology为三角形的曲面呢 不懂的线看这个pdf吧 When Bézier curves were invented it was immediately realised that there was a need for extension of the curve ideas to surfaces. The first surface type that was considered was what are now termed Bézier triangles [Farin1997]. The Bézier triangle surfaces that are considered here are defined over regular triangulations, although treatments of arbitrary triangulations are available. Before Bézier triangles can be defined however, barycentric coordinates must be introduced, as they can be used to provide an independent coordinate system that is local to a triangle.
