Today i was experimenting with the book “THE NATURE OF CODE“, BY DANIEL SHIFFMAN, and i crossed with a peculiar pattern in “Randommness” chapter about “Perlin Noise”.
For more information aboout the processing library and the perlin_nose_algorithm see https://natureofcode.com/random/#a-smoother-approach-with-perlin-noise .
This is the example used in the book :
See the Pen PerlinNoise by 31rat4 (@31rata4) on CodePen.
Something peculiar happens when i change the difference between time and offset:
See the Pen StrangePerlinNoise by 31rat4 (@31rata4) on CodePen.
This , somehow, makes loose the random patter of perlin noise.
I am going on futher investigation using math.
Following the current refence :
