Noise & texture guide

Start

The tool opens with Perlin noise already drawn at 512 × 512 pixels.

What you need

• A current browser. The picture is drawn on a plain canvas, so no WebGL or GPU is needed.
• A picture, only if you want to lay the noise over one.

Your first result

1. Open Noise & texture. Perlin noise is already there.
2. Pick a noise type from the list, or press a button under Presets.
3. Move Scale and Octaves, or type a new Seed, and watch the picture change.
4. Turn on Seamless tiling and open Tile preview to see four copies side by side.
5. Press Download PNG at the top of the panel.

Good to know

• The same seed and settings always give the same picture, so a seed is worth writing down.
• The line under the Noise sliders shows the picture's size and noise type.
• A picture you add is kept on this device, and every lab tool that takes a picture opens with it, until you press × on its tile. Here it is laid over the noise.
• On a phone the noise types and the controls sit in bars on the screen. Tap a bar to open it.
