基于分形和高度图控制的三维地形生成技术研究

3D terrain generation based on fractal theory and elevation map control

介绍了分形理论,论述了使用随机布朗运动和中点位移法生成地形的过程及其不足,并在分形理论的基础上提出了一种基于中点位移法和高度面控制混合的随机地形生成方法,介绍了对地形模型进行纹理贴图的方法及其实现,最后给出利用该方法生成随机地形的实例。

The fractal theory is introduced at first. Then the process and disadvantages of terrain generation when using random Brown movement and diamond square method are analyzed. Based on fractal geometry theory, a stochastic terrain generation algorithm is put forward by combining diamond square method with elevation map control. A special texture mapping method was implemented on the terrain. An instance of the model was shown in the end.
