室外小物体的快速渲染与持久化研究与实现

摘要

本文首先介绍了一种高效的室外小物体widget组的批量绘制方法，随后设计了一种基于高效使用内存的改进BSP树表示来快速生成widget可见集合的方法及其对应快速搜索策略，最后使用此方法实现了室外地形中地表小物体的高效快速渲染的一个Demo展示。%This paper first introduces the method of drawing an efficient outdoor small object group widget batch ,then designs a representation to the method of creating widget visible set search strategy based on improved BSP tree and its corresponding to the efficient use of memory ,and finally achieve the efficient and fast rendering terrain surface small objects in a Demo display using this method .
