基于B-Rep模型的三维实体的真实感显示

摘要

A data structure of B-Rep model-based 3D solid is introduced in this paper. The surfaces of 3D solid represented by B-Rep model are triangulated with Delaunary triangulation method. A special smooth shading technique is also introduced in this paper for upgrading the realistic representation quality of discrete curved surfaces.High quality representation result is obtained by using the techniques described above.%介绍了基于B-Rep模型的三维实体数据结构 。通过对B-Rep模型表达的三维实体的表面进行Delaunay三角剖分，对离散后的曲面采用明 暗处理技术，实现了三维实体的真实感显示，获得了效果逼真的三维实体真实感图形。
