摘要
提出一种基于三角面片的离散化实体布尔运算算法,探讨了算法的稳定性、准确性和高效性,在算法中使用容差控制和正则推理,对非正则的运算结果层层排除.在自主开发的CAD平台上对算法进行了检验,获得满意效果.
The discrete Boolean operations in CAD entity system are studied, their stability, accuracy and validity are discussed. Making use of tolerance control and regular reasoning, all kinds of invalid operations result can be separated in different hierarchy. Finally, a satisfactory result is obtained through verifying this algorithm in CAD platform developed by ourselves.
