摘要: CSG(Constructive Solid Geometry)是实体造型中一种重要表示方法.传统的CSG实 体显示方法不仅费时,而且难以控制明暗效果.本文提出的方法以一种新的CSG体素表面光 强生成模型为基础,结台深度缓冲技术,能快速有效地显示CSG实体,方便灵活地控制明暗效 果.Abstract: CSG(Constructive Solid Geometry) is an important solid modeling technique. The traditional shading methods for CSG models are not only costly, but also inefficient to control the shading effects. A new method is presented in this paper. Based on a new light intensity generation model for CSG primitive surfaces, and combined with depth-buffer technique, it can work quickly and control the shading effects flexibly.
