Using Perlin noise as a source of randomness is brilliant; I had never thought of that. I always think of Perlin noise as a field you can evaluate, but it makes complete sense that you can turn that field into a stream. The motion of the Perlin random walker is really satisfying, so much more so than any of the others; when I’ve tried to do randomish-walk-type things, I’ve usually had to resort to picking a random point and then doing some attractor-type stuff to get my walker there, and then picking a new point when I arrive, since most random walks look so unpleasantly inorganic.
Thanks for the link!
This is great (even if not comprehensive, it doesn’t have to be) education. Beautiful, informative, and mostly intuitive (particularly the walkers and the perlin variation). Lovely, thanks!
