中文摘要:
      随着信息化建设的快速发展,数字地球的理论与技术逐渐成熟。而三维地形作为数字地球最基本的组成部分,具有十分重要的作用。本文介绍了三维地形的建模和优化技术,并采用等高线数据,利用3ds Max软件完成了一个区域的三维地形建模,最后对优化后的模型进行了对比和分析。
英文摘要:
      With the rapid development of informatization,the theory and technology of digital earth has gradually come to maturity.The 3D terrain that is the most basic components of digital earth plays a very important role.This paper presents the modeling technology and the optimization technology of 3D terrain,and builds a 3D terrain model in 3ds Max based on contour data.Then the comparison and analyses of the optimized 3D terrain models will be presented.
