面向STL偏置模型的拓扑信息生成

为了更有效地生成和使用STL偏置模型,采用链表结构进行数据存储,并在去除顶点冗余的过程中,通过搜索各顶点在已定义的顶点链表中所记录的读入面片的顺序号,直接建立了点引用面的法向量的拓扑信息来完成偏置计算。算法应用实例表明,所使用的方法能够快速生成偏置所需的拓扑信息,合理使用了内存空间,并在此拓扑信息基础上快速地生成了有效的偏置模型。

Topological information generation for STL offset model

In order to generate and use the STL-format offset models effectively,the chain table structure is used to store the data,and in the course of merging vertexes,the topological information of normal vector of the facets linked to vertex is built directly by searching the vertex's order-number of reading facet which was recorded in the defined vertex-list.The case studied indicates the method can generate the topological information for offset quickly and use the memory space reasonably.Based on the topological information,the effective offset models can be generated rapidly.
