parametric representation of surface

基本解释

As soon as the parametric representation of the sculptured surface is known, the NC machining path on it is determined for the nonspherical cutters.
只要已知被加工曲面的参数表达式，就可运用点涉法在该曲面上生成非球面刀的数控加工轨迹。
With a parametric representation of the surface and introducing a relative metric matrix, the parametric domain is triangulated in order to get the surface triangulation.
采用参数表示法将空间曲面变换为平面参数域，引入相关的度量矩阵后将平面参数域进行三角剖分，最后得到空间曲面的三角剖分。
The parametric representations of curved surface and curve line are given. The advantage of this representation is also analyzed.
给出曲面、曲线的参数表示法，并且分析了参数表示法的优越性。
