In this paper, the algorithm of Tiled Directional Flow (TDF) is improved for real-time rendering river surface. To represent the reality of river flowing, the approach for building the river velocity field based on the procedural method is proposed. And the velocity field can be used to generate the flow texture of the TDF algorithm. With combining GPU, GLSL programming and LOD technique, the large scale river scene can be real-time rendered. At last, the results show that the solved velocity field can reflect the river flowing characters realistically. And the simulation results indicate that the proposed algorithm can be used to construct river scene with realistic virtual environment which also meet the real-time requirement in simulation.
