| Abstract: | A 3D realistic image is the core technique of scientific visualization, computer animation, and virtual reality, also is an important technique of spatio-temporal GIS. And modeling of terrain and visualization are important parts of creating 3D scene. This article puts emphasis on two methods of terrain modeling and realization with OpenGL based on introducing the realizing process of 3D terrain and modeling of terrain. Also this article contrasts and analyses different ways of modeling technologies and rea... |
