Abstract:

Based on the deep study of the principles of fractional Brownian motion and the random midpoint displacement algorithm, the relational expressions about different parameters of the fractal-terrain are deduced. Through the analysis of the influence of different parameters, a method for parameter-based  controllable fractal-terrain is proposed. Experimental results show it is convenient and effective on the control of fractal-terrain, and is an effectiv e measure for natural landscape simulation.
