Well done Yusef! I can think of one "real use case" - looking hella cool

[@saniancreations]

Right?! Imagine you are about to have a conversation with a computer in charge of an entire autonomous city, you walk into this huge deep black room, door closing behind you... and suddenly a face ten times larger than you, looking like this, emerges from the darkness.

[@Yusef28]

Ooo great visual and setting. Imagining that I'd say my gut feeling would be that I was somewhere I shouldn't be. Like (this might sound weird) if you've ever opened a computer or game cartrige and smelled it, it's like this space is not fit for human life) . Very interesting.

[@joshl.6826]

Thought I was just gonna see some cool trippy pixel effects and but also am served with some intriguing details on real world "Granular Convection" - actually learned something today 😄

[@Taxodium-d2j]

I too have discovered your channel through recommendations and I must say that beyond the interesting contents I really like your narration and voice. Very enjoyable to watch. Nice music choices too. I really like it, thanks for making my evening.

[@Yusef28]

This is great to hear, I was worried a bit about the narration but especially my voice in this one since audacity had a weird update. Glad to hear you liked the music and that I made your evening! ^^

[@chilaou]

i immediately started thinking about how to simulate this effect in a gouache or oil painting. Then I started thinking about making a texture brush in Clip Studio to simulate pixel sorting stretches. Then I remembered I could just pixel sort if I'm already working digital. xD I've never heard of this effect before, or thought about "sorting pixels" so how I found this suggestion for a video eludes me, but sorting and organization + art is pretty dope for my OCD. Loved the vid, great work~

[@Yusef28]

Great comment. The voronoi sorting effect was actually my first attempt at a pixel sorter that made things look painted. Glad to know I'm not the only one seeing the potential there.

[@AzuriumOfficial]

8:15 looks amazing, like a new type of ambient occlusion.

[@Sbenbobb9]

I really enjoyed your interest in all the subjects. The way you went from pixel sorting to granular convection, and then farmers dealing with field stones... It really shows that you give a s*** about the things you're studying. Keep it up dude, your videos are bound to be inspiration for someone else! I can tell you they are incredibly interesting to me and really make me want to continue to explore my interests.

[@Yusef28]

Thank-you, and I'm glad to hear it inspires you to keep exploring!

[@jocelynnielsen9154]

The Voronoi effect is very dreamlike. It feels a lot like the thing where something changes but doesn't actually change until later, like you're talking to your friend and then you realize actually it's your sibling and they've been your sibling the whole time, and you weren't talking you were pushing them back but actually they were never there you've been pushing on a wall but there's only a small resistance and you've walked like a hundred steps inside it.

[@Yusef28]

I definitely have dreams like that haha Nice!

[@terransky1]

This is incredibly cool work. Thank you for the in-depth explanations of what you were doing, and all the more technical details :) I’d love to try to implement something like this soon, I’m sure there’s a ton of more interesting effects you could do with this

[@Yusef28]

Yup it opens up lots of possibilities. I hope you go for it!

Genuinely insane that I learnt britbongs made their houses out of stones found after something called "The Brazilian Nut Effect" because of a pixel sorting video

Nice! That's exactly what I hoped some people would come away from this saying.

[@Yusef28]

Haha purrfect!

[@xomvoid_akaluchiru_987]

This actually looks awesome, I really did enjoy this video. I think my favorite sorting depends on the original image, but that diagonal method you showed in the thumbnail looks really cool.

[@arcadesmasher]

I don't know who wrote the code at 1:32, but not using spaces is criminal.

[@sakamocat]

for some reason, the most poorly looking code always perform the best

[@Yusef28]

Fair enough, I'll try to clean up the code on the next one.

[@Mecharuva]

Looks perfectly legible to me

[@mothesawy]

You are absolutely awesome. Your channel deserves more! Thanks for sharing this.

[@enilenis]

I've done a ton of these experiments in Python's PIL module, and even designed effects used in film about 15 years ago. I had written sprite engines that emulate the look. Didn't need a falling sand engine. Every pixel is a bunch of values. Color, position and sometimes other channels, if it comes out of 3D or uses CG matte paintings. So much math can be done with it. I had a friend in school and we were constantly challenging eachother to come up with mathematical patterns that looked interesting and could be animated with a time variable. And I still mess around with math to this day, just because it makes funky looking pictures that move. Sometimes in Python, sometimes in Maya, Blender, Houdini, Nuke, or anything else that has a scripting language built it.

[@Yusef28]

This is excellent. I always like hearing about people's programming journeys and the things that keep them interested over time and make it social. Also python ^^

[@enilenis]

​@@Yusef28 For me friendly rivalry was always a great motivator. I couldn't draw, but my best friend was good. So I decided to get better than him. Same with programming and math. Always started with someone being better than me at something and me wanting to be better than them. Competition often morphed into years-long friendships. One guy I used to always battle in competition, eventually joined me and we continued on the same team. Another mathematician friend became a roommate, and we had the most positive influence on eachother. We both ended up working in film for 20+ years with great careers. Competition is good. It encourages the person to keep improving.

[@Yusef28]

I totally agree with you! Competition can push people to do much more than they would otherwise. So much of human inginuity comes from competition. Although I am generally not very competitive by nature I get it and am even sometimes open to it for this specific reason. What do you think about the ESports world btw?

[@enilenis]

​@@Yusef28Thoughts on Esports? I generally do not follow them. I'll only pay attention if something shows up in headlines, like when a record is set, or when there is a cheating scandal. I rarely play games these days, and hence my interest in watching others play is also diminished.

[@Yusef28]

ah fair enough I guess that's basically me as well now

[@pinkmullet4]

Wow, most of this stuff was completely over my head but I was somehow still enthralled with it. Subbed.

[@Yusef28]

[@Yusef28]

[@basiliotornado]

7:30 That's a pretty interesting concept. I want to try playing with the fully sorted image, and unsorting it to see what's changed I think out of the effects you made, the diamond and the one at 5:59 are my favorite. Great video!

[@Yusef28]

Yup, and I cut this out of the video but there is another technique where you can sort two images both ways then transplate the colors from one to the other and then sort back. So you get the closest approximation of imageB with imageA's colors. Appreciate the feed back yeah those were two effects that were almost accidents(especially the bubbles) but ended up being hits.

[@orterves]

Very cool effects, and I like the "know enough to be creative" approach - it's a good lesson that we should read the papers, but not worry too much about totally understanding everything before giving it a go and seeing what cool stuff can be made. The understanding will come a lot easier with the hands-on knowledge that comes from doing

[@Yusef28]

Yup, if I had more time I woudl have given the paper a deeper read but it would be a waste if I never get to build anything haha

[@neon_light5608]

[@beemerwt4185]

"Somehow the sorting reverses direction when it reaches as far as it can go in one direction" Yes, that would be called an overflow.

[@theevilcottonball]

Way cooler than I imagined. The only sorting visual I ever did was running different sorts on a hilbert curve (on the CPU).

[@Yusef28]

That sounds interesting actually!

[@theevilcottonball]

​@@Yusef28I wanted visualise sorting algorithms on the pixels of an image Imagines are twodimensional, so you have to map it into 1D, a hilbert curve is just the most interesting way. It would also be ppssible to sort them from bottom to top. But then you don't see mergesort sorting smaller rotated 'copies' of the image into bigger ones.

[@Yusef28]

Oh ok that's a really neat approach!

[@g4pls]

[@DubUltra]

great content, well edited and concise :)

[@0osk]

5:34 looks so cool man. I wonder how your sorter would look if you picked the sorting direction based on motion vectors from the video? Could make some cool trailing effects or like a weird motion blur. Or reversing a video, running it through your sorter, and then reversing it again so the video plays correctly. Maybe the sand would kinda fall into place and build up objects as they appear?

[@Yusef28]

Oh yeah motion vectors have so much potential. Your video idea is also very unique and I can't quite predict what would even happen

[@trevorswope3263]

Dang, another banger from Yusef

[@Snipermain]

On the subject of this occurring in nature, the sorts where each quarter of the screen had diagonal directions reminded me of crystal growth. Bismuth crystals being a well known example, but theres plenty interesting crystal patterns. In the case of crystal growth it is "sorting" itself by growing in the direction in which it has the least resistance to do so. So it grows in a direction away from where it originated in the direction of a less hard material (air, water, minerals w less hardness, etc)

[@Yusef28]

oo I like this! Ok cellular automata for crystal patterns, I'll keep this in mind

[@katiebarber407]

i like it better without the blue noise, and i also like seeing the sorting happen in real time. great video

[@QW3RTYUU]

Yusef, Idk how much my ignorance will show here, but I remember vividly people telling me to not use if/elses when writing shaders, and I saw that your odd/even sort code at the beginning there is only if/else code. using branching logic makes it hard for the cpu to predict the branch and therefore adds misses to the whole thing which is something you want to avoid at all cost on gpus, you should instead do branchless programming. I hope that helps, you can probably ignore this comment because your stuff seem to work without my intervention. Nice video!

[@Yusef28]

Your comment is welcome here! I didn't put much thought into avoiding branching for this project to be honest and just moved on to other things afterwards but the next time I look at this I will.
