There exist already methods for combining random mid-point displacement method with curved-surface modeling to generate mountain terrain.

随机分形法和曲面造型法分别在地形生成的随机性和可控性方面能起到一定的作用。

NOTE: I keep saying similar because we are using a random method for generating the terrain, so it will be different everytime.

注意：为了更简单的解说所以我们采用了一个随机方法去产生一个地形，因此它每一次都不一样。

Special attention is given to the design of 3D engine, rendering of 3D scene, the algorithm of generating random fractal terrain, application of trajectory simulation.

重点讨论了三维引擎总体结构框架设计、引擎内部模型数据管理、三维场景渲染、随机地形生成的算法、弹道仿真等技术的应用。
