no vote
Application background Through the given DEM data terrain rendering, using OpenGL to achieve and through roaming to achieve real-time terrain and browse. LOD technology to achieve multi-resolution terrain generation. Key Technology The key technology is the use of OpenGL function of DEM data is firstly drawn, in drawing after the texture mapping to draw a good terrain becomes true, then through the LOD technology enable roaming in the terrain more realistic
