Circling back to a dead end.
These renderings never really went anywhere. They show chaotic orbits around 3 fixed attractive potentials while varying a uniform magnetic field. There are some lovely sweeps and folds as the chaos unfolds. I also like the glowing effect as the orbits get tightly wrapped around the centers of attraction. There wasn’t much to this other…

Simple Op Art disk
This is what you get if you take the parallel stream from the rest of the series and replace them with a circular spray from the center of the distortion. Â Everything gets bent uniformly when it hits the ring. Â Moving to second order equations gives you the freedom to have multiple directions from a single…

Twist #3
Double twist and wrap. Â While the last image was on the lackluster side, this one has everything turned up to 11. Â There is a strong deflection as the particles pass through the first peak and then they are swung back again as they exit the ring on the other side. Â An important thing to notice…

Bouncing Circle Grid
I’m pleased with the motion on this one. It’s still just experimentation, but the results are promising. Related Images:

Twist #2
While this isn’t as dramatic as some of the other images, it shows what happens as either the velocity of the particles increases or the strength of the distortion diminishes. Â Instead of dramatic changes, things just tighten up a little bit and bend. Related Images:

Simple twist
This shows the distortion in flow from a simple annular distortion. Â It’s part of a series that started with “distortion” and “a single twist and spray“ Related Images:

A single twist and spray
One of the most popular images I’ve developed (I’ve no idea what verb to stick here) is this basic geometric op art style piece. Â I was just using a very simple mask to test out using differential equations to generate families of curves. Â It’s grown on me, and I’m starting to put some more images…

Supercharged performance
I was going back through some of my old posts and making sure the javascript still works, and I loaded up the three.js particle system test code I put up a while back. Instead of being broken, it was even faster in chrome than when i wrote it. I was surprised at how much of…

Grids of circles
Ooooh, this is getting interesting now. Â This shows a grid as the spacing changes from wide to small spacing. Related Images:
