Simple Divergence-Free Fields for Artistic Simulation
Mayur Patel, N. Hall Taylor · Journal of Graphics Tools · 2005
We discuss tools for calculating divergence-free fields for artistic particle simulations. We introduce a simple, fast divergence-free noise function which can be used for turbulence. We also describe how the interpolation technique used by the noise function can be used for calculating artist-controlled divergence-free fields. The artist can create realistic unbounded flow fields without the complexity or memory cost of voxel-grid methods.
