This looks like a very useful project and I like the name. One thing I did notice, though, is that it is using older Perlin noise for its noise. Perlin noise is smooth, but it produces a lot of 45 and…

I have been catching up on Voxels with a focus on coherent noise and I hit:

When I try to get noise using the 2D function, I get an out of range exception.
Here's my usage:
```
float max = 0.0f;
float min = 0.0f;
float sum = 0.0f;
flo…

The 3D noise functions, such as the 3D simplex noise, 3D fractal simplex noise, etc. seem to only use the first two channels of the uv, period, and offset/shift vectors. I thought the purpose of a 3D …

You currently have the permutation table defined as:
```
private static readonly short[] P =
{
151,160,137,91,90,15, ...
};
```
If you instead [randomly select those values](http://forum.unity3…

### Topic
I think Simplex Noise would be a very good enhancement. It seems p5.js is not working on it. If you want to make sure that the previous projects don't break.
A fix for this may can be do…

32-bit seeds aren't great, and pervasive use of mostly-0 seeds may be causing odd results already. I propose that `impl Seedable for T` be replaced with `impl Distribution for Standard` per rand 0.5 c…

simplex noise in 3D with double precision integers produces a wrong noise patters that is not in the bounds of `[-1,1]`.
here is an example that samples the noise at a coordinate where it is out of…

Simplex noise is computationally simpler and produces good results. See here:

There seems to be a good implementation here:

There are some implementations which generate a slightly different result
