Modeling Falling and Accumulating Snow
The use of computer graphics to produce special effects is currently being applied with great results in especially the entertainment and game industry. One area where computer graphics is not quite ready to replace all real effects is natural phenomena where a lack of general models exists. In this work we present a general model for falling and accumulating snow. The appearance and movement o...
متن کاملOrigin of diversity in falling snow
This paper presents a systematic way to examine the origin of variety in falling snow. First, we define shape diversity as the logarithm of the number of possible distinguishable crystal forms for a given resolution and set of conditions, and then we examine three sources of diversity. Two sources are the range of initial-crystal sizes and variations in the trajectory variables. For a given set...
متن کاملFalling Snow Retrieval Algorithm Development Work for Gpm
Retrievals of falling snow from space represent one of the next important challenges for the atmospheric, hydrological, and energy budget scientific communities. Estimates of falling snow must be captured to obtain the true global precipitation water cycle, snowfall accumulations are required for hydrological studies, and without knowledge of the frozen particles in clouds one cannot adequately...
متن کاملRendering falling snow using an inverse Fourier transform
Methods for rendering falling snow typically use particle systems [Reeves 1983] which requires tens of thousands of particles (snowflakes) and thus can be expensive. Here we present an alternative method for rendering falling snow which does not use particles, and instead uses an inverse Fourier transform. Our idea is based on a well-known fact that pure image translation with velocity (vx,vy) ...
متن کاملA Spectral-particle hybrid method for rendering falling snow
Falling snow has the visual property that it is simultaneously a set of discrete moving particles as well as a dynamic texture. To capture the dynamic texture properties of falling snow using particle systems can, however, require so many particles that it severely impacts rendering rates. Here we address this limitation by rendering the texture properties directly. We use a standard particle s...
