本文介绍了一种新的预处理可见性工具。它将视图空间和对象空间分区放在一起,以控制可见性求解器生成的可见性描述的渲染成本和内存成本。所提出的方法逐步细化视图空间和对象空间的细分,同时最大限度地减少相关的渲染和内存成本。与以前的技术相反,这两种细分都是由实际可见性信息驱动的。我们表明,一起处理视图空间和对象空间提供了一个强大的方法来控制所产生的可见性数据结构的效率。
This paper describes a new tool for preprocessed visibility. It puts together view space and object space partitioning in order to control the render cost and memory cost of the visibility description generated by a visibility solver. The presented method progressively refines view space and object space subdivisions while minimizing the associated render and memory costs. Contrary to previous techniques, both subdivisions are driven by actual visibility information. We show that treating view space and object space together provides a powerful method for controlling the efficiency of the resulting visibility data structures.
