【Abstract】 The 3D terrain generation techniques is the one of important research issues in the computer graphics. The most useful methods of three dimensional terrain simulation were described, emphasis is laid on the modeling techniques based on fractal geometry of three dimensional terrain. Finally, several mathematical models for generating three dimensional terrain are discussed in details using the midpoint displacement technique .更多还原
