摘　　要：大规模室外场景中漫游并实时渲染问题是目前图形学和虚拟现实中研究的热点,其中如何有效地剔除场景中无关物体,将关系到实时渲染的速度和质量.基于现有算法,提出地形采用分块管理和对场景中物体进行视锥扫描的方法来绘制整个室外场景.实验结果表明,该方法在大规模室外场景中漫游并实时渲染上能取得较好效果.In large scale outdoor scene roaming real-time rendering technology is a research hotspot in the computer graphic and virtual reality, how to effectively cull the invisible object in the scene will be related to real-time rendering speed and quality. Based on the existing algorithms, it presents rendering terrain using block management and culling objects using frustum scanning meth- od to draw the entire outdoor scene. The experimental result shows that this method could be a- chieved and improve visible effect.
