Particle System Based Snow Simulating in Real Time

This paper deeply study in real-time simulation technology of realistic snow scenes, including snow real-time rendering techniques (real-time rendering of falling snowflakes), snow accumulation model, and wind field simulation (snow wind interaction model). The proposed innovations of this paper are:A snow particles cluster systems: which increase both the rendering efficiency and variety of the snowflakes; Wind snow interaction based on Boltztnann equation and D3Q15 model: this model simplify the calculation and offer a very true view, the algorithm can run in real time as well. These three solutions as above can notable increase the real characteristics in snow visualization and computation efficiency.
