Noise1D

Using 1D Perlin Noise to assign location.

// All Examples Written by Casey Reas and Ben Fry

// unless otherwise stated.

float xoff = 0.0;

float xincrement = 0.01; 



void setup() {

  size(200,200);

  background(0);

  frameRate(30);

  smooth();

  noStroke();

}



void draw()

{

  // Create an alpha blended background

  fill(0, 10);

  rect(0,0,width,height);

  

  //float n = random(0,width);  // Try this line instead of noise

  

  // Get a noise value based on xoff and scale it according to the window's width

  float n = noise(xoff)*width;

  

  // With each cycle, increment xoff

  xoff += xincrement;

  

  // Draw the ellipse at the value produced by perlin noise

  fill(200);

  ellipse(n,height/2,16,16);
