核辐射安全仿真实时交互渲染方法

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.%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.
