You can used the checkboxes to show or hide the picture, the noise or the hue variation.
The hue variation uses the noise to smoothly update the colors with random tints.
Algorithm radio buttons allow you to used Perlin Noise or Simplex Noise algorithms.
The noise seed is randomly picked. You can use the Refresh Noise button to get a new seed.
| Slider | Effect |
|---|---|
| Speed | Define how fast the noise and the hue variation evolve |
| Intensity | Set the noise less or more visible |
| Frequency | Increase or decrease the number of cycles per unit length |
| Octaves | Define the amount of noises that are added together to form final noise |
| Persistence | Define how much influence each successive octave has |
| Lacunarity | Define how quickly the frequency increases for each successive octave |

The frame per second may vary based on your browser. The performance appears to be better on Mozilla Firefox.
In case of performance issues use small-sized images and try to limit the use of octaves.
