基于深度缓存和BSP树技术的表面消隐技术研究

Research on Surface Blanking Technology Based on Depth Buffer and BSP Tree

主要介绍了两种消隐技术,深度缓存算法是通过两个缓存来实现的,其中的一个是用来存放颜色的颜色缓存器,而另一个是用来存放深度的深度缓存器。BSP就是二叉空间分区树,将视景中要显示的多边形或者实物,使用二叉树的原理组织成一种数据结构,通过这种数据结构存储多边形(实物)。

This paper describes two blanking technology. Depth buffer algorithm is achieved through two caches, one of which is used to store the color of the color buffer, while the other is used to store the depth of the depth buffer. BSP is a binary space partition tree, the scene of polygons to be displayed or in kind, using the principles of organization into a binary tree data structure,the polygon（in kind） is stored by means of this data structure.
