As an aspiring plotter artist (is that a thing?) I find this to be a very good resource, thanks for putting it together.

This is really cool and super informative! I used Perlin noise in a side project of mine a couple months ago to make cool textured planets, which you might enjoy checking out https://vinaybhaip.com/blog/2021/01/26/perlin-planets

This is a very important concept to understand in visual design too. Sometimes perfect alignment, symmetry, etc... can be the wrong way to do something. Hardly anything in nature is 100% symmetrical. These are sometimes things that go unnoticed by the conscious mind but your subconcious will pick up on it.

For some reason I thought this would randomly generate a test-drive suite that you'll to pass by creatively implementing whatever makes the random tests pass.

Note the algorithm is patented(!) per Wikipedia: https://en.wikipedia.org/wiki/Simplex_noise#Legal_status

There are six patent claims that I have no interest in reading. Apparently there is also an OpenSimplex noise for circumventing the patent, but it only goes up to 4D [simplex usefully goes up to 5D].

I was caught off guard by this! It just always felt like simplex noise was just perlin v2 and I never thought twice about the legal status of it. The 2022-01-08 Anticipated expiration is definitely something to look forward to here, especially since the current owner (an investment firm) appears to have >100 ongoing patent litigation cases, with patents as vague as network load balancing.

Reading the patent itself, there's definitely some weirdness to it, like how specific it is about application to texturing. I believe heightmaps would be acceptable (IANAL).

In slightly unrelated news, a bunch of Microsoft patents on fonts expired last October.
