Eroded terrain simulation based on improved hydraulic erosion algorithm

In order to improve the traditional terrain simulation with the problem of high computation cost and poor visual effect, a novel eroded terrain simulation technique for computer games is developed. Water Map and sediment map are utilized for the improvement of traditional hydraulic erosion algorithm to achieve more convincing simulated effects. Moreover, four acceleration methods are employed for algorithm optimization to ensure real-time simulation. Experiment results show that the new technique is robust and efficient to simulate photorealistic eroded terrain for real-time computer games and animations.
