Line 6: Noises based on lattices, such as simulation noise and Perlin noise, are often calculated at different frequencies and summed together to form [[band-limited]] [[fractal]] signals. Another approach to this problem is to analytically build vector functions that are guaranteedly divergence free as a result of vector calculus identities. Examples of this approach include "Curl-Noise" as suggested by Robert Bridson, and "Divergence-Free Noise" due to Ivan DeWolf. == References ==
