Photorealistic terrain generation method based on fractal geometry theory and procedural texture

In this paper, we provide an efficient method to generate the terrain used in games and simulation systems. We propose the midpoint displacement method to generate the heightmap of terrain, and give the procedural texture method based height value to create the texture map of terrain. This method can generate different style terrain by changing the roughness and sampling percent. The terrain being created by this method can be used in simulation system and games, so a lot of scientific research fee to buy DEM data can be saved. Firstly, this paper shows the midpoint displacement method. Then this paper provides the procedural texture method based height value. At last, this paper gives the implements. The implements prove that our method is feasible and valid. And our method has also been used in the practical projects.
