一种基于法线贴图的爆炸烟雾模拟算法
Algorithm of explosion smoke simulation based on normal-map
摘要
Abstract
Conventional smoke rendering methods based on computational fluid dynamics(CFD) and smooth particle hydrodynamics(SPH) can achieve vivid explosion smoke, however, they can hardly meet the real-time requirements because of the low performance, what's more, common simulation methods based on particle system aim at the general smoke mostly, which need large number of particles, fail to create realistic and stereoscopic explosion smoke effects. Proposed an explosion smoke simulation algorithm based on normal-map,used the normal-map to simulate the 3D property of the smoke particles, based on which, random lights are employed to process lighting calculations, the rolling and expanding of explosion smoke are simulated by use of simple movement control model. The experiments show that this algorithm can produce high-realistic and animating explosion smoke effects with few particles and good real-time performance.关键词
