An accumulated method based on fractal for automatic terrain generation

Abstract

In this paper, an accumulated method for automatic terrain generation was proposed which was based on the fractal theory. The Fault formation algorithm is used to generate an initial model of terrain. By controlling the iteration and amplitude of Fault formation, we can get diversified Contoured Terrain. Then the MPD (Middle Point Displacement) method of fractal theory is used to iterate the initial model, which results in more terrain details. The main advantage of the method is the combination of automaticity and controllability. On the one hand, Terrain Feature Templates can be automatically generated by the various values of the parameters of Fault formation. On the other hand, arbitrary level detail can be produced by the various values of the Fractal parameters. The experiments prove that our method is feasible and valid and the realistic terrain can be generated through the method.
