Whenever real-time snowfall is animated in computer games; no snow accumulation is simulated; as far as we know. Instead; so-called zero thickness is used; which means that the blanket of snow does not grow when the snowflakes reach the ground. In this paper we present a method for simulation of snow accumulation; which simulates the different stages; starting with a snow free environment and ending with a totally snow covered scene; all in real-time. The main focus is not on the physical properties of snow but on speed and visual result.
