WebPerlin noise in its basic form has the same general look and feel as a sine wave. Its amplitude and frequency vary somewhat, but the amplitude remains reasonably consistent, and the frequency is restricted to a fairly narrow range around a center frequency.

WebSo a seeding method that sets z, e.g. z = 10.0 * seed, could work for "seeding". Another way to seed the noise function would be this: If you always just get noise in a range of [0.0; 64.0 [ for x and y, one could seed the noise by adding an offset to x, y or both when calling the noise function: noise (x + 64.0*seed, y + 64.0*seed).
