The Research for the Realistic Rendering and the Parallel Method of the 3D Terrain Scene based on OpenGL
The Realistic rendering of the 3D terrain scene always is used in some Cosmically Synthetic Distributed Simulation System. These systems sometimes have the demand of Parallel Rendering, such as long-range displaying scene. As an opening industry-standard on graph, the OpenGL will effectively realize the Realistic rendering of the 3D scene. On the basis of analyzing the intrinsic character of the OpenGL, the paper illustrates one realistic rendering of the terrain scene. Then we discuss the realistic rendering process of the 3D terrain scene based on OpenGL and analyze the parallel method of OpenGL program on LAN. This research will be help for deep into the study of the Parallel Rendering technology in Cosmically Synthetic Distributed Simulation System.
