在3ds Max中进行三维地形建模时,一般以等高线为基础,通过Terrain工具生成三维地形。这样的三维地形精确度比较低,难以满足用户的实际需求。本文以某项目的三维地形建模为例,研究如何将大数据量的离散点数据导入3ds Max实现高精度的三维地形模型。通过分析研究3ds Max所能接受的数据类型和离散点数据特点,提出了将离散点数据导入ArcGIS,利用ArcGIS进行特征点线的添加修改、数据的平滑处理、三维模型的导出,最后将生成的模型导入3ds Max,而后建立高精度的三维地形模型的技术路线。实践证明,此方法具有良好的可行性。

Terrain models carried out in 3ds Max are general based on contour and made by the Terrain tool.And these terrain models are hardly to support users＇ needs because of low accuracy.This paper researches how to import large amount of discrete data into 3ds Max,and realize high precision three-dimensional terrain model.Terrain Visualization,taking the terrain mapping of a project as an example.The paper focuses on analysis of the data type and data feature which can be accepted by 3ds Max;and propose a technical route by importing data to ArcGIS;modifying characteristic points,characteristic lines,doing data smoothing,exporting 3D models in ArcGIS;and importing the result model into 3ds Max,and generating High-precision three-dimensional terrain model.In practice,the feasibility of this process is proved very good.
