【摘要】 STL文件描述的是一种离散的实体表面三角面片模型,在实际处理中一般需要重新构造其邻接拓扑关系(包括面片的邻接面、顶点的邻接面、邻接顶点等关系)。而剔除STL面片数据中的冗余顶点是重构的关键,该算法已经成功应用于三维真实感注塑模流动模拟软件的3D图形处理。更多还原

【Abstract】 STL format is a kind of solid model which consists discrete surface triangle face. It is necessary to rebuild adjacency topology relation between faces in practicality application. Filter the redundancy vertex in STL solid is very important. The algorithm is successful to deal with 3D graphic in realistic mold flow simulation software.更多还原
