It's been quiet on the demo front as my musician side has recently taken over. Here's the latest piece by me and Noira, you'll find a couple more on the same Salixvelox channel:

Following my recent 2D image morphing demos, I've been thinking of visualizing the process as a single 3D shape.

From a pile of shit, new life grows. Conway's Game of Life running independently in the 3 colour channels in 64x64 cells with wrap-around topology.
Not much new code here, just added image loading capability to my old pile-up demo of 2D cellular automata.
Let's try a fancier/heavier morphing idea. Each point from one image is paired with the nearest point from the other. Then we can linearly interpolate the position of each to move between the two pictures.

A basic algorithm for a basic guy: find the edge points in the binary image and change their colour to that of the target image. Rinse and repeat until the edge no longer moves.

New Year's Redactions
My earlier text redaction demos were done in my OpenGL setup, using a pixelation effect overlaid on a text document. This was rather simple, but it required some manual tweaking to align the pixelation grid with the text. I've now redone the effect in text mode using Python.

Rule/Yule 30 cellular automaton with a "band-pass" filter every few iterations. Done in the Bash shell using bitwise math, so each row/state is a single number of 63 bits.

Hej tatta gorem! Koska ATK-laitteiden tuottama teksti on nykyään in, hip ja wow, niin tehtiin @noira_musti kanssa oma runogeneraattori. Uniikit tekstit löytyvät osoitteesta algoristo.com/markoviinike... tai nettisivujeni kautta.

Another blow-up view of the Apollonian spheres, now dropping on a concave surface to gather all the jetsam together. This is what I had in mind when writing the first drop demo, and the model just needed a bit of refinement for the differently sized balls.
New demo just dropped! Testing a basic elastic model with blocks of FCC, BCC and diamond lattice.

Deforming Apollonian spheres, again using some interesting math that Bluesky doesn't want me to explain in this limited space.
Making Apollonian gaskets usually follows a key rule of iterated function systems: each iteration should make the thing smaller. With inversions, this means going from the outside to the inside of inverting circles.
However, it's possible to make valid gaskets using a lopsided configuration, where
Another look at Apollonian spheres, cutting out the top half and showing a few iteration steps.

New implementation of the Apollonian Gasket iteration
2D circle inversion fractals on the spherical surface. This was a fun offshoot of my recent Apollonian endeavours, again using the Riemann sphere mapping to go from 3D to 2D for the iterations.
Apollonian gaskets via circle inversion.
For more explanation, you should see my posts on Instagram, Youtube, Facebook or Mathstodon where the posting limits are more sensible.

Apollonian gaskets based on Platonic solids. The vertices of a tetrahedron/octahedron/icosahedron are used for the centre positions of the initial circles.
Riemann sphere mappings of Apollonian gaskets.
Since my 2D gaskets are fitted to the unit circle, they cover exactly half of the Riemann sphere, as seen in the first part. My lazy solution to covering the entire sphere was a simple copy-paste, and the result doesn't seem too bad.
Another look at the Apollonian gasket. This shows that the process doesn't use simple inversion, since that would distort the image within each disc.

Back to basics: I made an Apollonian gasket generator based on Descartes' theorem, as explained on Wikipedia. The method involves some nontrivial details on the choice of +/- signs, which I had to figure out on my own.
