Visualization Research of 3D Radiation Field Based on Delaunay Triangulation

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.
