  Seed option for noise

  Posted by Tudor Baican on October 22, 2022 at 3:44 pm

  <div>Hello friends,</div>

  I’m playing around with the noise function. It’s there a way to change the seed of the values?

  Thanks for your help.

  noiseMulti = 10;
  fr = 10;
  amp = 200
  seedRandom(1268, true);
  n = noise(time*fr)*amp*noiseMulti;
  [0,n];

  noise() is a 3D Perlin noise field that accepts a number or a 2 or 3 item array as its input. So you could do something like this:

  noiseMulti = 10;
  fr = 10;
  amp = 200
  seed = 1268;
  n = noise([time*fr,seed])*amp*noiseMulti;
  [0,n]

  Oh this is a bit embarrassing, better I read the documentation more thorough.

  Lot of thanks.🧐
