　We propose a new modeling method for the appearance of fallen snow formed by snow drift near bulidings and other obstacles. Instead of computational fluid dynamics simulation for wind-driven fallen snow, we employ the Pre-computed Radiance Transfer(PRT) technique [Sloan et al. 2002] to handle snowflakes which fly, hit and fall with the wind blowing to all directions around obstacles. This approach approximates snow accumulation with snow drift heavy fluid dynamics simulation compulation.
