摘　　要：根据三维空间立体剖分特点,采用逐点插入法对空间离散点的三角剖分进行改进;对理论计算或实测产生的辐射场离散数据进行重构,得到三维空间内连续分布的辐射场数据;最后结合VR仿真技术,构建某核设施的三维仿真场景,并利用可视化映射技术,实现虚拟环境中的三维辐射场的可视化。结果表明,VR技术与Delaunay三角化方法结合使用可显著提高三维辐射场可视化的质量与效率。Based on the characteristics of the three dimensional partition,the triangulation of discrete date sets is improved by the method of point-by-point insertion.The discrete data for the radiation field by theoretical calculation or actual measurement is restructured,and the continuous distribution of the radiation field data is obtained.Finally,the 3D virtual scene of the nuclear facilities is built with the VR simulation techniques,and the visualization of the 3D radiation field is also achieved by the visualization mapping techniques.It is shown that the method combined VR and Delaunay triangulation could greatly improve the quality and efficiency of 3D radiation field visualization.
