The Implement of 2D Perlin Noise

Warning

Don't use this repository's core algorithm. I'm very not sure that my algorithm is correct perlin noise algorithm. I don't burden any consequence if you use this repository or get a wrong answer.

This repository is just for fun. I create this repository after reading some perlin noise's articles. And almost algorithm is created by myself. I almost don't use any existed algorithms. This is the reason why I suggest that you don't use this repository's algorithm. I'm not sure that my algorithm is correct.

Brief introduction

Basic

This app support hybrid perlin noises. You can assign 2 or more noise configs and app will mix them automatically. At the same time, the compute time will be increased.

For each independ noise function. We support these config:

• Seed
• Frequency
• Amplitude
• Redistribution
• Interpolation
• Smooth (Unsupported currently)
• Attach percentage

App will output a 512x512 bitmap which contains 2D perlin noise. This size couldn't be changed.

App support colorful output and gray output. You can set this config in Generate setting page.

Octaves

We don't support explicit octaves. Because we support alterntive, noise hybrid list. But, you still can use octaves via openning the tab called Octaves helper. In that page, app will display 2 settings and you can edit them. Then, click the button. A series of octaves' noise functions will be added into noise list automatically.

In obvious words, Noise list replaces octaves and noise list provides more mix settings. We use a tab to help you to create octaves function quickly.
