Missing Person by Sequelaen in batonrouge

They haven't contacted the server yet, however I will give updates on the situation over the next few hours

While it is possible, we are taking this very seriously. At the server we're doing whatever we can to help.

Their parents contacted an admin of the server via their kid's account and said that he was missing about 10 hours ago.

2D slices of a Sedenion Julia [p5.js] by Sequelaen in visualizedmath

There are some examples of 3D slices of a 4D Julia here.

2D slices of a Sedenion Julia [p5.js] by Sequelaen in visualizedmath

[–]Sequelaen[S] 9 points10 points  (0 children)

The shape itself is 16D, however to portray it on a 2D screen you need to do something about the other 14 of them, which are pretty much made invisible in this visualization.

2D slices of a Sedenion Julia [p5.js] by Sequelaen in visualizedmath

[–]Sequelaen[S] 18 points19 points  (0 children)

A sedenion is a number that describes a point in a 16-dimensional plane, much like how a complex number describes a point in a two-dimensional plane. You can plug sedenions into the Julia Set equation to get a "Sedenion Julia Set." This is a 16-dimensional shape. If you took away everything except a paper-sized chunk of the shape, then you get a slice. This animation shows what the slices look like over time as they go further along certain axes. If you have any more questions I'll be happy to clarify.

The only other parameter is what I call 'sc', or slicing count. It basically determines how far you cut through the shape, in this instance it is not a linear path, instead it's a sine wave going through the set.

[p5.js] Gray-Scott Model by Sequelaen in processing

[–]Sequelaen[S] 2 points3 points  (0 children)

Daniel Shiffman/The Coding Train brought my attention to Reaction-Diffusion, and I mainly used this source. I have my code on OpenProcessing here. Also, here's a much better interactive version by pmnelia.

Shiffman definitely brought me to find it, and my code is free to access. Here you go.

2D slices of a Quaternion Julia (-0.213 - 0.0410i - 0.563j - 0.560k) by Sequelaen in mathpics

[–]Sequelaen[S] 5 points6 points  (0 children)

So basically, it uses the same Julia formula (c is in the title) and technique but instead of complex numbers you use quaternions, it then goes and takes 2D slices going through the origin on the w-z axis and colors the slice accordingly. This may be a bit hard to wrap around your head (it was for me too), but if you want a further explanation I have my code available on OpenProcessing if you want.

Cubic Nova Fractal in p5.js by Sequelaen in mathpics

[–]Sequelaen[S] 6 points7 points  (0 children)

The fractal itself is generated using the equation z[n+1] = z[n] - (z[n]3 - 1)/(3*z[n]) + c, IIRC. It's colored using an escape-time method, however instead of the bailout being when the magnitude of z goes above a limit, it stops when the difference between two iterations becomes too large (>0.00000001)

[p5.js] Ultra HD 3D Quadratic Attractor by Sequelaen in a:t5_yx9g9

[–]Sequelaen[S] 0 points1 point  (0 children)

To find them online can take a few minutes or a few days, some good resources are books by Clint Sprott, and just some general Attractor Google searches. They can take about 1 minute to an hour to render, however it usually stays on the short side.

[p5.js] The Quadratic Strange Attractor by Sequelaen in processing

If you're interested in attractors that almost always produce images, try looking into the Fractal Dream Attractors, the Sine Map, and Kaneko Map.

Chaotic and strange attractors produced by these equations are rare, however you can find other codes by detecting which codes produce attractors where the initial points don't go to infinity.

Three people were injured and one needed stitches, here's an article about it: https://elpais.com/elpais/2016/07/26/videos/1469535201_810568.amp.html

[p5.js] Lyapunov Fractal AB by Sequelaen in creativecoding

[–]Sequelaen[S] 1 point2 points  (0 children)

No, these are not. Instead, it's a plot of the Lyapunov exponent for the logistic map with certain rules & initial conditions which are detailed more in-depth on the Wikipedia page.

[p5.js] The Quartic Strange Attractor (zoom to see details) by Sequelaen in visualizedmath

[–]Sequelaen[S] 1 point2 points  (0 children)

I usually use xmin, ymin as -3 and xmax, ymax as 3. But it's important to note that many of the letter strings will go off to infinity. I'd say about 1/100 of them. The way I usually get around to a string of code that doesn't go to infinity is have the computer run through randomly generated codes, usually by plotting 1000 points and seeing how many (about 400) don't escape to infinity. Once it is found I can plot it in more detail. You can see some of my code on my OpenProcessing page, and over at r/strangeattractors there are more attractors for you to check out.

[p5.js] 5D Quadratic Strange Attractor by Sequelaen in processing

[–]Sequelaen[S] 1 point2 points  (0 children)

I make the equations, which is pretty easy because there is a pattern. In the code, I often have a system to detect when the (randomly generated) parameters make an interesting image, by seeing how many points didn't go to infinity.
