Heat Transfer Simulation for Modeling Realistic Winter Sceneries

This paper presents a physically based method for simulating the heat transfers between the different environmental elements to synthesize realistic winter sceneries. We simulate the snow fall over the ground, as well as the conductive, convective and radiative thermal transfers using a finite volume method according to the variations of air and dew point temperatures, the amount of snow, cloud cover and day‐night cycles. Our approach takes into account phase changes such as snow melting into water or water freezing into ice.
