| Abstract: | Terrain is a kind of complex physique in the nature, three-dimensional terrain technology is a key technology of virtual reality. It is a complex task using geography space data to constitute a reality, real-time, exchangeable terrain environment. Three-dimensional terrain build technology and real-time display three-dimensional terrain technology are introduced by using OpenGL. |
