Wow, these necessary-disorder GIFs are a plethora of intriguing ideas! Thank you Dan, for taking us the first few steps in that direction! You always claim that you don't have a great artistic instinct, but you have an amazing eye for possibilities! And that fits perfectly to what you are doing here.
I loved that ending, it's so different, but fitting! I'd love to see more of you outside of the studio talking about things, whether it's a whiteboard in a park or spheres and ropes on a sidewalk or stuff like that! =D
Instead of simply mapping the noise to either 0 or 255, multiplying it by a large enough number will achieve a similar effect, but near the edges you'll get some anti-aliasing for free, which looks substantially better. You actually did that on accident in a previous video where you multiplied the value by 255 twice.
An interesting consequence of using this rotational plane approach: the difference in radius between one end of the plane and the other means one side of the image will be passing through the noise field at a higher rate than the other. The more you try to compensate for that difference, the longer the resulting loop.
Are you not going to mention that 4D is needed so that the plane can loop but still every part of the plane moves through space at the same pace? (Which makes me curious as to what a 3D implementation would look like.)
You only need one additional dimension to represent time so 3d noise is plenty to make a loop. You just need to move the entire coordinate space instead of only shifting a singular time axis. Kinda like looking at a cut-away slice of a torus.
I've always used a circle made from a Midpoint Circle algorithm. You'll avoid the trig functions, and have all the loop points at setup. And of course you can scale/stretch those points, etc.
Now make it so it can take different paths through 4d space, render out multiple ones, then pay them in a random sequence to obfuscate the looping. THEN, have some and at other 4D points, with some starting there, with all paths leading to close loops. I call it a 4D time flower.
your videos are the BEST. I watch them when I have problems coding. one question: at the end, I see a familiar neighborhood. Do you by any chance live in New York? again, best RUclips channel I have ever seen.
I think it’s possible you can implement your torus slice explanation more literally and not invoke noise of higher dimension than 3 and still loop 2D noise. Although if your torus is small there may be a visible ‘boiling speed’ gradient across the slice as the points more distant from the axis of revolution will boil faster than the inner points on the slice that are closer to the torus axis. You want a torus like a hula hoop, not like a donut. But with a hula hoop it’s hard to get both slow boiling and a short loop duration. While with a donut it’s hard to get even boiling speed across the slice.
The Coding Train actually it occurs to me, and maybe you mentioned this or the animator who makes the gifs mentions it already, that you could work with 3D noise but instead of it being a function of XYZ it could be a function of rho, theta, and z. Cylindrical coordinates. Then there would be no speed gradient penalty across the slice for small donuts.
The Coding Train I thought I had it working in Maya, but I used the dot product for my cylindrical angle and it loops, but it goes backwards and forwards. I’m starting to see the problem with the cylindrical coordinate systems and 3d.
Etienne Jacob not if your 3d noise is s function of rho, phi, and Z instead of x, y, and z. The cylindrical coordinate system will allow you to have constant evolution rate across the slice. The noise itself will be crushed into fanning planes that radiate from the central axis. And you'll still only be using 3D noise.
Etienne Jacob I’ve been playing with it in Maya and I have a seamless cylindrical texture using the dot product for angle but half of it mirrors the other half. is the problem with 3d cylindrical coordinates that the texture goes backwards and forwards. I’m starting to see the problem now that I’m trying it.
For everyone who's interested: pastebin.com/NGfVDiMS You can use the code when you run it inside Processing and you have the OpenSimplexNoise.java tab with the class inside it. Also you will need to install the PeasyCam Library so you can move the camera around freely. The library can be installed by going to Sketch -> Import Library... -> Add Library... and then searching for PeasyCam. There's also a second draw loop which does not use a circle but a 2d plane instead.
At the whiteboard, he was suggesting that this looks like a 3D torus, but the implementation is in 4D. If it was a 3D torus as he drew, then yes one side would animate more quickly, but he rotates the 2D plane in two extra orthogonal directions. For a comparison that is easier to imagine, think of a line segment rotating about one end like a propeller in 2D (one extra dimension). In that case, the animation speed would vary place-to-place on the line. But if you imagine instead rotating the line in 3D (2 more dimensions) like it's travelling around the round side of a cylinder, then all the points of the line are moving at the same speed/animation rate.
Thanks for this explanation! Do you think my analogy of the torus is too misleading? It's the way I like to think of it, but I'm worried maybe I'm leading people astray. If you like to write a short explanation / correction I could include it in the description or pin a new comment!
Yes, if you didn't offset the rotating plane away from the rotation axis, the bottom edge of the screen would not change. I assume you have to get it far enough away from the rotation axis so that the difference in "speed" between bottom and top edges is not noticeable. Oh wait there are other comments about this and saying the 4D noise makes it irrelevant. ruclips.net/video/3_0Ax95jIrk/видео.html&lc=Ugw77BdmjxYhAylk9PF4AaABAg.8s60aNhK0jr8s62h3R6hVB
Would it be possible to iterate some params for the noise to match the sun at a given instant. Then I would get a machine learning params = model() and the noise algorithm as the loss function. A way to figure out what the sun is doing and predict it.
Got a question, can you do a tutorial on how to install processing on a raspberry pi 3? I finally got my pi up nd going, but everything I find on getting the programming language on the pi is out dated and doesn't work.
Anyone know how we can generalize the 4d looping to n dimensions? For example if we wanted to create this exact coding challenge in 3d, we would need a 5d noise loop.
Dan do you think a masters in mathematics is worth it? I'd love to understand the higher level math that goes into graphics programming, and I think it would compliment a CS bachelors well.
What do you do outside of yt? (If you do sth) because this is all in like processing so more visual based. I know that you know alot about java outside of visual stuff but then why are the challenges always visual challenges? The cap at the end is nice on you btw

"Entitled" has two meanings. The first and more common is "to furnish with a right or claim to something". The second is "to give a name or title to". The various writing style guides are divided on whether "titled" and "entitled" can be used interchangeably.

There really is no need to use 4D noise here. 3D works too, just loop your XY plane around a circle in the XZ plane. it will produce a similar result and is much faster.
so nice and amazing. but i want to give coding challenge, to create a 4d universe using Einstein's field equation. i hope, you will accept my problem as well as challenge.
your torus example is not very accurate, you are actually looping around the four-dimensional equivalent of the torus. you would loop in a torus-like shape if you changed y and z instead of u and v. but then the upper part of the image would change less than the lower part and you wouldnt wnat it to,
McLP not if your 3D noise is a function of (radius, angle and Z) in cylindrical space, instead of regular XYZ space. Then there’s no speed gradient across the slice.

You could've used two 2D noises with different offsets if you wanted to decrease lag.
By the way your voice sounds different outside of your studio.
Can you elaborate how do I do that? I am actually trying to animate and loop a 3d noise which means I would need a 5d noise.
