Realization of smooth connection of bicubic b 233 ; zier surface patches 曲面片光滑拼接的实现
The results of analysis show that the workspace of parallel machine tools is enveloped by many surface patches 分析计算结果表明,并联机床的工作空间是由多张曲面片包围而成的闭包。
The boundary curves correspond to a set of rectangular or triangular topological type that can be represented with tensor - product or degenerate b - spline surface patches 其中边界曲线对应于可用于张量积b样条曲面的具有矩形结构的曲线集合。
The tool path can be adapted according to the shape of surfaces meanwhile the break , gap and overlap between adjacent surface patches are eliminated 该算法将加工曲面离散成三角化模型,在三角化模型中直接生成无干涉刀位轨迹,刀轨生成与刀轨干涉处理统一在一个演算法中。
In order to realize 3d garment intelligent design , this paper brings forward a method to set up 3d garment model with form - points controlled spline and bi - cubic surface patch 摘要为了实现三维服装款式智能设计,提出以形值点控制的样条曲线和双三次曲面构建服装立体模型的方法。
