Abstract:
1. A method or graphically simulating stretching and wiggling liquids using one or more computer devices, the method comprising steps for: modeling multiphase materials with a grid of nodes for dealing with multiphase behaviors including complex phase-interface dynamics; and simulating stretching and wiggling liquids using a Eulerian vortex sheet method, which focuses on vorticity at a liquid-gas interface and provides a user control for producing visual effects and employing a dense (high-resolution) grid for surface tracking in addition to a coarse (low-resolution) simulation grid, which downsamples a surface in the high-resolution grid into the low-resolution grid without a volume loss resulting from aliasing error, wherein employing the dense grid for surface tracking is performed by a liquid-biased filtering, in which liquid regions of the coarse grid enclose all liquid regions of the dense grid by simply shifting the level set threshold value.
