Nice examples, I think I landed on that page quite a while ago. I love Processing and Perlin noise. One thing I enjoyed was using Perlin noise values to compute a "region" on the canvas and making the behavior of a particle depend on which region it was in. Examples:

The Processing code I wrote to make them is here: https://github.com/Brian-Fearn/Processing/blob/main/PerlinNo...

If you're into exploring this sort of thing yourself, I can extremely highly recommend Daniel Shiffman's Nature of Code[1]. It's among my top-5 recommended books about computing in general, let alone for algorithmic art. [1]: https://natureofcode.com/

Also his "Coding Train" videos on YouTube: https://www.youtube.com/@TheCodingTrain

If you dig Perlin noise fields, the next stop is fBM (Fractional Brownian Motion). Inigo Quilez has a good article about it - https://iquilezles.org/articles/fbm/

Couldn't help myself and asked Google Studio to one shot this: https://perlin-noise-fields-explorer-560691554368.us-east1.r...

One of the cool things to do with Perlin noise is to build a kinda predictable random number generator. Good for games.

Curl Noise[1] is also cool. I've used it to create some gas giant planets for video games [2] though I used opensimplex noise [3] rather than perlin as the base noise, but either will work.

I learned a lot about perlin noise when generating virtual worlds for Wurm Unlimited fascinating stuff and very satisfying when you get results you’re looking for.

Every article on that site is wonderful.

Very beautiful. I am a complete newbie, so I might be asking about something obvious -- does anyone know how some of these would relate to plotting random Polya vector fields ? For example, one can take a sum of complex rational functions of the form f_i(z) = r_i / (z - p_i) where (r_i,p_i) are complex numbers drawn from some random point process, say a generalized Poisson one. One needs to plot the conjugate of sum_…

Beats me too! Thanks for the heads up.
