Shape-Variation
- 摘要: 研究了调节凸 B¨|zie 曲面、B-样条曲面及 NURBS 曲面(BBN 曲面)一个控制点以后,曲面形状变化的规 律.通过将 BBN 曲面分解成一张凸曲面与具有特殊形状曲面的叠加,建立了曲面变形前后一些几何量与变形位 移量之间的数量关系,得到了凸BBN曲面失去凸性的充分条件和判据.相应的结果可应用于调节与控制BBN曲 面形状的算法设计. -Abstract: The regulation convex B ¨ | zie surface, B-spline surfaces
Computing-the-Parameters
- Nurbs曲线/曲面在反求参数上的数值不稳定性,是Nurbs曲线/曲面的致命缺点.该文介绍了用于参 数曲线/曲面求交的活动仿射标架(moving affine frame,简称MAF)方法.基于MAF方法的原理,提出了反求 Nurbs曲线/曲面参数的一种新方法.该方法在数值稳定性和效率上均高于各种传统的迭代法,并已应用于商 品化三维CAD系统GEMS 5.0. -Nurbs curve/surface parameters in reverse numerical instabi
