摘要
叙述了一维造型一般状态树求值法求物体的交 ,二维造型的集合运算分为合并、遍历、收集、选择四个步骤 。
The calculating ways of One-dimensional molding's normal state tree is used to work out objeat intersection;set operation of two-dimensional molding's have four steps:merging?all_visiting?collection and selection;three_dimensional molding normally adopts structure of radiative edge to represent object model.
