Simplex noise
American computer scientist who invented gradient noise in 1983 and simplex noise in 2001, the smooth randomness behind most generative textures and flow fields.
Noise Field
Horizontal hatches displaced by simplex noise. The drawing is the noise itself, with no particles, no field walking.
About this pattern
