摘要
传统的基于"面模型"的三维地形可视化,难以逼真地模拟现实世界的复杂地形,本文在充分了解体素的基本概念和特点的基础上,分析了几种常见的体素模型,主要讨论了体素在多分辨率三维地形可视化方面的研究和应用情况,为建立基于"体模型"的虚拟地理环境提供参考。
It is difficult to realistically simulate the complex terrain of the 1real world for the traditional three-dimensional terrain visualization based on Face model. In this paper, on fully understanding the basic concepts of the voxel and its features, some common voxel models were analyzed. It focused on the the research and application of woxals on the multi-resolution three-dimensional terrain visualization. The result could provide a reference for establishing the virtual geographic environment based on ＂volume model＂ .
