Realization of smooth connection of bicubic b 233 ; zier surface patches 曲面片光滑拼接的實(shí)現(xiàn)
The results of analysis show that the workspace of parallel machine tools is enveloped by many surface patches 分析計(jì)算結(jié)果表明,并聯(lián)機(jī)床的工作空間是由多張曲面片包圍而成的閉包。
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 其中邊界曲線對(duì)應(yīng)于可用于張量積b樣條曲面的具有矩形結(jié)構(gòu)的曲線集合。
The tool path can be adapted according to the shape of surfaces meanwhile the break , gap and overlap between adjacent surface patches are eliminated 該算法將加工曲面離散成三角化模型,在三角化模型中直接生成無(wú)干涉刀位軌跡,刀軌生成與刀軌干涉處理統(tǒng)一在一個(gè)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 摘要為了實(shí)現(xiàn)三維服裝款式智能設(shè)計(jì),提出以形值點(diǎn)控制的樣條曲線和雙三次曲面構(gòu)建服裝立體模型的方法。
