    Practical Simulation of Surface Tension Flows


    Visual effects often requires the simulation of natural phenomenon such as water, explosions, steam, or fire. For The Cat in the Hat, Rhythm and Hues was required to simulate a character-animated fish interacting with water in a fishbowl.
    In small-scale fluid motion, surface tension provides an important visual cue for depicting the physical size of the underlying fluid. Waves driven by surface tension, called capillary waves, travel much faster over the water surface than waves driven by gravity, which are generated at larger scales.
