Ensemble of points with noise

[glv]

Hello @humano ,

The reference for noise() states:

The resulting value will always be between 0.0 and 1.0

• translate origin to center of sketch
• subtract 0.5 from noise() to center it about 0… -0.5 to 0.5.
• multiply by a scaling factor f
• vary scaling factor f with mouse to see dynamic display.

Your code with modifications:

float u = 0;
float v = 0;
float w = 0;

void setup()
  {
  size(1000, 1000);
  colorMode(HSB, 100, 100, 100);
  //noLoop();
  }
void draw() 
  {
  background(0);
  noStroke();
  
  translate(width/2, height/2);
  
  float f = map(mouseX, 0, width, 0.2, 3);
  
  for (int x = 0; x < 1000; x += 12) 
    {
    for (int y = 0; y < 1000; y += 12) 
      {
      u = u + 0.1;
      v = v + 0.11;
      w = w + 0.1;
      float n = (noise(u)-0.5)*f * 1000;
      float m = (noise(v) -0.5)*f * 1000;
      float l = noise(x/100.0, y/100.0)*30;
      
      fill(random(0, 100), 100, 100);
      ellipse (n, m, 1+l, l+1);
      }
    }
  }

Have fun!
