this paper has a research on the following problems:(1) curvature monotony condition for the quadratic rational b spline curves.
本论文就自由曲线设计中以下几个问题进行了一些研究:1.二次有理b样条曲线的曲率单调条件研究。
the curvature monotony condition for the quadratic rational b spline curve is derived by using the skew coordinate system that can reduces the calculation process.
