摘　　要：In order to visualize the 3-D field of explosion and describe the complex physical phenomena of explosion, the 3-D data resulting from numerical simulation by 3-D multi-material in cell (MMIC), and the application of volume visualization is explored, based on the characteristics of explosion and shock. Based on this, a visualization system for 3-D explosion--ViSC3D is designed. Approaches for the visualization of 3-D field of explosion are presented. The algorithm and the functions of ViSC3D are also presented. ViSC3D is thus a useful tool to observe and analyze either the full picture or the details of a 3-D field of explosion, that are difficult to observe and analyze directly. With ViSC3D, the field of explosion between the hill slopes is visualized. The cutaway views and 2-D slices are also given. The full picture and partial details of 3-D field of explosion can be observed clearly. Furthermore, ViSC3D can be used to visualize other similar 3-D data fields.为了将三维爆炸场可视化及分析爆炸过程复杂的物理现象 ,从三维多流体网格法得到数值模拟结果 ,基于爆炸与冲击的特征 ,采用直接体绘制的方法进行三维可视化 .在此基础上 ,设计了三维可视化软件———ViSC3D .介绍了三维爆炸场可视化的理论、方法及ViSC3D软件设计的算法、功能 .该软件是三维爆炸场的重要分析工具 ,可以便于研究人员对难于直接观察、分析的爆炸场进行全貌和细节的观察和分析 .利用ViSC3D ,对山沟中的爆炸场进行了整体、剖面可视化及二维切片的抽取 ,比较详细地展现了爆炸场的概貌和局部细节 .ViSC3D软件亦可适用于其它类似三维数据场的可视化 .
