Is 0 value at lattice points an artifact?

[edit]

@SiegeLord


"An artifact of some implementations of this noise is that the returned value at the lattice points is 0."


It looks more of a feature for Perlin noise:

- "the noise function will pass through 0 at every node, giving Perlin noise its characteristic look"

- https://en.wikipedia.org/wiki/Perlin_noise#/media/File:Perlin_noise_with_contour.svg


The only artifact seems to be "directional" ones:

- "visually-significant directional artifacts"
