noisegen is a web-tool used to generate noise and coherent noise using a variety of algorithms.
The resulting images may be used in a number of applications from background images, terrain heightmaps, textures, and more. It is also intended as a learning platform for the exploration and understanding of the various noise generation techniques.
The following 2D noise algorithms are available, or will soon be available, for use. They are split into 'pure noise' and 'coherent noise' categories:
Pure Noise (via Random)
- Mersenne Twister 128 (not yet available)
- Mersenne Twister 19937 (not yet available)
- Perlin Noise
- Simplex Noise
- Worley Noise
- Wavelet Noise (not yet available)
- Diamond-Square (not yet available)
The following are example images generated by noisegen.
Perlin Noise (Raw & Clouds)
Simplex Noise (Raw & Islands)
More examples may be found at http://www.noisegen.io/samples.html.
A high-level feature roadmap may be found on the wiki at https://github.com/ssell/noisegen/wiki/Feature-Roadmap.
