Experimental study on implicit representation of time 内隐时间表征的实验研究
Basically , they can be classified into three categories : mesh representation , parametric representation and implicit representation 这些方法大体上可以分为三类:网格表示、参数表示以及隐式代数表示。
An implicit equation with guaranteed differential properties is obtained by simple combinations of the primitives implicit representations using r - function theory . the surface corresponding to the zero - set of the implicit equation is efficiently and directly polygonized using the primitives parametric forms 但是,要得到所构建物体的外表面,也就是相关隐函数的零集合,需要对隐函数进行显示求解或使用一些面片生成算法如marching cubes算法。
