River simulation based on Poisson disk distribution

To solve computation overhead problems and to improve plausible visual effects, a novel real-time river-simulating method based on fluid dynamic formula was introduced. A Poisson disk distribution algorithm to achieve a well-structured distribution pattern in screen space was proposed. The algorithm generated distributed particles to depict the river velocity field and to reconstruct the water interface. A texture sprite technique was used to render the river surface efficiently by dynamic accessing and blending to textures. Simulation results show that the presented method can produce a physically plausible flowing river scene and it meets the requirements of real-time simulations.
