Lattice Boltzmann Flow Simulation with Particle System

摘要：

Considering the characters of flow field for nature scenes, this paper applies GPU-based LBM computing into rendering natural scenes with large-scale particle system. We present a new Frame Buffer Object (FBO), multi-channel rendering process and GPU-based particle system combination methods. We propose a new GPU-based rendering pipeline to update the velocity of Boltzmann flow field and the positions of particles through two GPU textures at the same time. Finally, several natural scenes, such as spreading smokes, moving fog, snowing and scattered petals, are realistically simulated in real time.
