Best noise transformations?
I've been working with some terrain generation with noise, particularly Simplex and Worley noise, with DLA mountains too. There are obvs many ways to mathematically shift, change and combine these techniques, but finding the best and most interesting ones is undeniably difficult.
I have managed to create a few interesting terrain types (images below) with the following:
\- Sinusoidal rolling hills with z += 1-cos(x+sin(y)) (with different scaling ofc)
\- Volcanoes with sinusoidal transformed worley
\- Shield walls: (1-abs(noise))\^p
\- Ravines: 1-normalize((1-abs(x))\^3)
\- River cliffs: abs(normalize((worley + noise), -0.5, 0.5))
\- Grass flatlands: low octave noise\^p
\- Flat top cliffs: sigmoid(normalize(x, -1, 1))
\- Terraces = normalize(x\^s1 * [round(x) + 0.5*(2*(x - round(x))\^s2\])
\- Spikey winter mountains = normalize(((1-worley(x))\^p +1)*(noise(x)))
These are really fun results, so it makes me crave some more combinations. In particular I've recently implemented domain warping and it looks like it has some really good potential for improving and shaping terrain, so using that would be cool.
I hope to hear some of the best terrain gen techniques !!

Discuss: generating curlicue within a rectangle
I'm thinking outside the border, trying to generate picture frames. Most of them have interesting curlicue in the corners. Because it's for a plotter it has to be some kind of vector. I've looked at Euler spirals and simulating two bar linkages, as well as walk accel + jerk with occasional jerk sign flips.
I imagine a top-down view of a skateboarder in an empty pool, always approaching but never leaving the edges. Maybe that's something?
So, dearest hive mind, what do you suggest?

Trouble with Perlin noise
So, Perlin noise as I think of it looks like this:
https://preview.redd.it/jhfufstpryke1.png?width=492&format=png&auto=webp&s=694ad8b9bdec0770667e48c2ae55d3c02d0f16e7
And if you set some threshold and convert it to black and white, it looks like this:
https://preview.redd.it/85kbcoxrryke1.png?width=496&format=png&auto=webp&s=bd6d4f5da6a133d7d16860b3e392cb1f54e725c2
Those images were made in python with the perlin_noise library. The problem is, every point has to be computed individually, which is very slow. So I found vnoise, a vectorized Perlin noise library that takes numpy arrays as arguments, and here's what it looks like:
https://preview.redd.it/lxukwjqtryke1.png?width=494&format=png&auto=webp&s=4db8c8b55951e7cbe99018b0f85f2eef9cc26ab2
Looks fine, until you convert to black and white:

For some reason, this Perlin noise has a bunch of straight vertical and horizontal edges, which is no good for what I'm doing. My questions are:
1) Is that a valid Perlin noise implementation, or is it a bug that I should report on the project's git page?
2) Does anyone know of any other vectorized noise libraries in python? I'd greatly appreciate it if I didn't have to make my own noise.
