Interesting. Is this the OpenSimplex2F or OpenSimplex2S noise? I do plan on completely replacing the implementations of 2D and 3D in both, with faster non-lookup-table based versions soon. 4D will...
Oh - in that case I suggest using FastNoiseLite. Its simplex has better gradient tables than original FastNoise, so it doesn't have as many diagonal patterns. https://github.com/Auburn/FastNoise/tree/FastNoiseLite It's actually the...
Wow I didn't realize it was that long ago that I made that comment! I started it finally. Non-final updated OpenSimplex2S C# here: https://github.com/KdotJPG/Noise-Extras/blob/master/alternative_implementations/OpenSimplex2S_Stateless.cs Has the 2D and 3D versions,...
The GLSL version compares the actual plane boundaries between points to determine which are closer, while the C# version uses a sequence of points to check until it has found...
Cool to hear! Interested in seeing the final result. I will soon be updating this repo with faster versions of the noise based on what I wrote for FastNoiseLite (https://github.com/Auburn/FastNoiseLite),...
The versions released prior to now could not be generalized straightforwardly, but the 4D function in OpenSimplex2F I just released can be generalized to N dimensions. I may do a...
It can! In 3D you will have four A3 lattices spaced out by , or in 2D you will have three A2 lattices spaced out by . The initial step...
I covered a bit of that in a post here. Should cover at least some of it. https://www.reddit.com/r/proceduralgeneration/comments/hm9bam/opensimplex2_4d_implementations_now_available_new/fxcyo2q/ Let me know if you have any more questions in particular!
FWIW I just updated the repo with new instancelessly-seedable versions, which also greatly reduce the use of lookup tables.
