中文摘要：
因核辐射安全仿真场景具有结构复杂和多角度交互式漫游等特点,导致仿真过程中难以实现实时交互渲染。本文提出了一种针对核辐射安全仿真实时交互渲染方法,通过仿真场景数据自动分割、仿真场景面片级视锥体裁剪、基于图像空间的跟踪地图等技术,从多个方面研究提高实时交互渲染效率的途径。以国际热核聚变实验堆ITER极向场线圈PF4维修过程仿真为例对本文方法进行了测试,测试结果表明该方法能有效提高复杂场景渲染效率,满足实时交互渲染。
英文摘要：
Because of nuclear radiation safety simulation scene is featured with complex geometric structure and multi-angle personnel roaming location tracking,etc.it leads to low rendering frames and unable to realize real-time interaction during virtual roaming.This paper presents a real-time interactive rendering method for complicated scene.This method can improve rendering efficiency mainly from three processes：automatic segmentation of simulation scene data,view frustum culling,roaming location real-time tracking based on plane map.It has been applied in the maintenance simulation of International Thermonuclear Experimental Reactor（ITER）PF4 repair.The test result shown that the method can effectively improve real-time interactive rendering efficiency.
