Experiments with Simplex Noise

For the main part, I use three cases of noise: alfa, beta and gamma. Alfa is regular simplex, beta uses the alfa noise in as an added dimension, gamma uses the beta in an added dimension. They are usually used like (noise(x,y) + noise(4x,4y))/5*4

The code is not pretty. I have gradually added more and more as I go further down, and sometimes going up to change something else. Consider it stream-of-consciousness coding. For instance, it was only when I reached the end, that i recalled i had planned to write a paragraph beneath each demo. The span element added in the first demo for this purpose, goes all the way down before I use it and then change it to an p-element instead.

Topological view of Alfa/Beta/Gamma

Alfa, beta and gamma noise side by side in topological view. Each line is created by walking orthogonally on the gradient on the simplex noise heightmap (constant height). The points used are random.

Particle lines

Particles in 3D w/ velocity determined by the simplex space determine where the lines should go

Alfa, beta and gamma noise side by side (should probably have done this at the top as well). With particle movements like this, one can see that the paths converge with the beta and gamma noises and you see less detail
