Function noise

noise(x?: number, y?: number, z?: number): number

🧮 Generates a noise value based on the x, y, and z inputs.

Uses Perlin Noise by default.

Parameters

Optionalx: number
x-coordinate input
Optionaly: number
y-coordinate input
Optionalz: number
z-coordinate input

Returns number

a noise value

Example

q5.draw = function () {
	background(0.8);
	let n = noise(frameCount * 0.01);
	circle(0, 0, n * 200);
};

Example

q5.draw = function () {
	background(0.8);
	let t = (frameCount + mouseX) * 0.02;
	for (let x = -5; x < 220; x += 10) {
		let n = noise(t, x * 0.1);
		circle(x - 100, 0, n * 40);
	}
};

Example

q5.draw = function () {
	noStroke();
	let t = millis() * 0.002;
	for (let x = -100; x < 100; x += 5) {
		for (let y = -100; y < 100; y += 5) {
			fill(noise(t, (mouseX + x) * 0.05, y * 0.05));
			square(x, y, 5);
		}
	}
};
