A practical method of realistic 3D terrain generation

CHEN Chang-lin①,WEI Hai-ping①,ZHANG Song②,WANG Feng①③(①Institute of Surveying and Mapping,Information Engineering University,Zhengzhou 450052,China;②The Center of Surveying and Mapping of Beijing,Beijing 100042,China;③PLA 61363,Beijing 710054,China)  
To build realistic 3D terrain,it often depends mostly on remote sensing image,and its realization is also comparatively complex.This thesis presented a practical method to build realistic 3D terrain:create texture making use of digital map,add 3D effect on the texture by PhotoShop,add light information to it by OpenGL,and project it to the simplified 3D terrain at last.Following this process,we developed a HeNan 3D Terrain Simulation System,which had a comparative reality and speediness.
