New accumulated method for automatic terrain generation
一种新的累加自动地形生成方法*

Based on the fractal, an accumulated method for automatical terrain generation was proposed. The Fault formation is considered as the generator of feature height of terrain. By controlling the iterations and amplitude of Fault formation, we can get diversified Contoured Terrain. Then the MPD(Middle Point Displacement) method of fractal theory which is based on fBM is used to iterate the initial model, which results in more terrain detail. The main advantage of the method is the combination of automaticity and controllability. On one hand, Terrain Feature Templates can be automatically generated with various parameter`s value of Fault formation. On the other, arbitary level detail can be produced with various Fractal parameter`s value. The experiments prove that our method is feasible and valid ,and realistic terrain can be generated.
