3D noise repeats itself #19

Closed endolith closed 3 years ago

endolith commented 3 years ago

Maybe this is just the way the algorithm works, but neither 2D nor 4D noise repeat themselves, so it seems odd to me.

3d is repetitive Figure_0

tmp = OpenSimplex()
N = 100_000
x_max = 5000
t = np.linspace(0, x_max, N)
for x in t:
    out_2d.append(tmp.noise2d(x=x, y=y))
    out_3d.append(tmp.noise3d(x=x, y=y, z=0))
    out_4d.append(tmp.noise4d(x=x, y=y, z=0, w=0))

Yeah feels more like it's part of the algo. Really gotta compare the results from other libraries and languages.

Thanks for the notice! Going to close this one though, as it's too similar in scope to #18, sorry
