英文摘要：

A novel scenario terrain simulation technique for computer games is presented. To emulate the erosion phenomena of natural terrain caused by air slaking factor, water map and sediment map are employed to improve the traditional hydraulic erosion algorithm, therefore the reality of terrain simulation are reinforced. Four acceleration techniques are employed to achieve integral algorithm optimisation for ensuring real-time simulation effects. Experimental results show that the new technique is able to simulate photorealistic terrain for real-time computer games and animations.
