FastNoise VS NoiseNormalizer

If you go to the FastNoiseLite github you'll see there's a FastNoiseLite.glsl file, this file contains the entire library. So to use this in a shader we need to use the new shader #inlude preprocessor. In short, create a new ShaderInclude resource, paste the contents of the FastNoiseLite.glsl file into it and then simply #include it in your shader.

Fair enough. If it helps, you can drop this into a P5.js sketch without too much friction: https://github.com/Auburn/FastNoiseLite/tree/master/JavaScript

I suppose I'll compile what I can find here for future searchers: Here's the original github for FNL , it has some images to use as examples but few explanations unless you want to download and run the preview program yourself.

Also take a look at FastNoiseLite if you want better control over noise generation, and for cool examples.

Yeah, that's literally what a seed does. It's really odd to me that the unity mathematics one doesn't have a seed. I use this one: FastNoiseLite

I really like this library which appears to have gals implementation. https://github.com/Auburn/FastNoiseLite

For the actual dunes I used fast noise lite ( https://github.com/Auburn/FastNoiseLite ). They have a nice gui app, where you can create noise textures (in my case voronoi noise). Then I apply the height map to the individual terrain tiles. So no fancy procedural Generation is going on here.

I think Simplex 4D could benefit from that in almost as good of a way. I haven't tested this myself, but the unskew constant to change to would be 0.3618033988749895 or changing the - to a + in the unskew constant so it becomes (5.0f + SQRT5) / 20.0f. I computed this by taking the unskew constant, writing out the full unskew matrix, multiplying by a rotation matrix, seeing that it can be converted back into a constant, then seeing that it just amounts to the sqrt term sign change. The new scale value will be (TBD - running NoiseNormalizer as I type this, will update with result).
