The Research of 3D terrain visualization based on ArcGIS And 3DMAX

摘要

The paper researches how to import the large amount of discrete data into 3DMAX and realizes high precision 3D terrain modeling. By analyzing and researching the data type and the feature of discrete data which can be accepted in 3DMAX, this author proposes a technical by importing data to ArcGIS, adding and modifying the characteristic points and lines, smoothing the data, exporting the 3D model in the use of the ArcGIS, and finally importing the result model into 3DMAX, and then generating the high precision 3D terrain model. In practice, the feasibility of this process is proved very well.
