摘　　要：针对基于面模型的战场地形要素建模与可视化的不足,提出利用体素模型实现战场环境地形要素的建模与可视化方法和基本思路。对基于特征点的双重移动立方体算法进行改进,实现体素地形的可视化表达,引入体素地形可视化的影响因子便于对体素地形可视化效果的控制,通过实验进行分析,得出最佳取值空间。In view of the deficiency of the Battlefield terrain feature modeling and visualization based on the Face Model, this paper proposes the methods and basic ideas of the terrain factor modelling and visualization using Voxel Model. The feature points - based Dual Marching Cubes algorithm is improved, and the visualization of voxel - based terrain is realized. In order to easily control the voxel - based terrain visualization, the factors are proposed which are affecting the visualization. Through the analysis of experiment, the optimum values are got.
