Application Study of 3D Terrain Scenes Simulation Based on Random Fractal

It discusses the self-affinity, nonlinearity of fBm and the complexity, irregularity of the realistic terrain, analyzes the traditional Diamond-Square algorithm in the midpoint displacement method, which is the most close to fractional Brownian motion. This algorithm may have the shortcomings that when generating terrain it is prone to crack. Then proposes an improved algorithm based on iterative Diamond-Square. The method can avoid cracks or wrinkles problems in the middle of regional grid array, making the terrain more verisimilar. The experiments are carried out via Visual C++ and Open GL environment. Results show that as long as the iteration time is moderate, the value of motion parameter H is chosen properly, the simulation terrain of different shapes can be generated randomly.
