Generating realistic models of landscapes with drainage network is a major field in computer graphics. In this paper, we present a fractal based method which generates natural terrains using ridges and rivers information. As opposed to methods that compute water erosion for a given terrain model, our terrain mesh is generated constrained by a predefined set of ridge lines and rivers network. A new extension of the midpoint displacement model is used in this context. The resulting landscapes meshes leads to realistic rendering and our method seems to be very promising.
