| 摘 要： | 文章在分形理论的基础上，结合Diamond—square算法，利用OpenGL的API提供的图形库，创建了一种快速生成地形的网格模型，既做到了对地形总体地形轮廓的控制，又充分地利用分形特性表现了地表面的丰富细节．软件实现及实验结果表明，算法生成速度快，只需存储地形参数，既大大减少了数据输入。又降低了系统资源的占用．

| Abstract: | The study based on fractal theory and Diamond-square Algorithm, using the function which OpenGL provide,establishes a kind of Mesh Model of quickly generating terrain, which can both control the macro-shape of terrain and represent abundant details of terrain surface. The speed of generating terrain is fast,it can only save the terrain preferences instead of saving a large quantity of data using in the model. This mode leads to a calculating method by which we could decrease the number of input data and the occupation of system resource and consequently make good effect. |
