The noise that shoves each crossing
American computer scientist who invented gradient noise in 1983 and simplex noise in 2001, the smooth randomness behind most generative textures and flow fields.
Warped Grid
A regular lattice, each vertex shoved by simplex noise. The drawing is the grid’s own edges after the shove: a cloth, not a triangulation of random sites.
About this pattern
Ken Perlin's simplex noise, 2001
Lay down graph paper, then shove every crossing with simplex noise, a different shove in x and in y, so the sheet buckles like cloth. Warp is how far a vertex may travel, in units of one cell; scale is how fast the shove turns from neighbour to neighbour. Distinct from Delaunay Mesh: the connectivity stays the regular lattice. Distinct from Noise Field: both directions are drawn, so you get a mesh, not a hatch.
