The noise() function

• • Watch FunProgramming [video 36]

  • Here is a program I wrote

float x = 200;

float y = 200;

float r = random(255);

float g = random(255);

float b = random (255);

float noisevalx = 2;

float noisevaly = 4;

void setup()

{

size(400, 400);

background(0);

strokeWeight(3);

}

void draw()

{

stroke(r,g,b);

x = x + (noise(noisevalx) - 0.5)* 10;

y = y + (noise(noisevaly) - 0.5) * 10;

point (x,y);

noisevalx = noisevalx + 0.3;

noisevaly = noisevaly + 0.2;

}

• • Change the program to make the drawing “more loopy”

  • Change the program so that both the color and the position and the color change with noise();
