He doesn't need volumetric simulations for creating nebulae.. His "buggy"code works just fine for that!

It looks like a star forming then going supernova Edit: after finishing video, the entire thing just looks like star simulation

Interesting how semi stabilities with a core and outer layer emerge on its own. Like the sun. Including solar flares. Brilliant video. ☀️

Pezzza: "I have a bug in my code". Also Pezzza: Creates a star.

"It can be exploited to create *funny things*" Truly, this is the thing that binds all avid users of technology together.

Makes me think our universe could just be a bug in a higher dimension universe

This is probably one of the most beautiful and impressive simulations I've ever seen. I'm pretty sure humanity has discovered the secret of the universe by now, but counted as a memory leak on their program and just fixed it away.

lovely, absolutely stunning Technical question: How does one even stabilize the energy at such high pressures? This is a really valid stress test for any physics engine

I love this! It's like watching a film but the "script" is just the variables changing. Beautiful stuff as always!

I wouldn’t say this is funny, I would say this is perfection in art form

1 : and that, kids, was how the universe appeared 2 : and that, kids, is how the sun will die

Pezzza's audience : "Absolutely stunning! Mesmerising! Chilling! Enjoyable!" Pezzza's CPU : "Aaaaaaaahh!!" "Thanks guys, but I'm dying down here!"

This is brilliant. I always look forward to seeing your videos as they're generally fascinating.

What if each particle created it's own gravity, I wonder what the redults would look like!

This is like when artists got so good at making art look realistic that they had to start making it ugly and abtract in order to show off how good they were. Pezzza is transcended beyond simulating real life, now he makes art out of "buggy" code.

I love this. Beautiful as always. You're one of my greatest sources of inspiration right now

This would make a really interesting screensaver, at least, so long as the number of objects didn't actually increase the power usage whenever it turned on.

As much wrote - bugs handles nuclear reaction like it was created to. Very nice and if i didn't know i would think that originally created for this

Makes me want to get into the graphical side of programming.

amazing job ! looking forward to the publication of the code :)

Pizza man always delivering straight gold. Seriously, if bars were in videos, ur shit would be spittin fire son. nawmean. SPITTIN FIRE

every once in a while i just binge your videos and recently these beta test videos where you discuss the variables and how they effect the objects really give me inspiration to add more to my game. This video and your newest one about smoke have given me two wonderful ideas. Thanks for all the amazing work you put into your videos.

This is one of the best video I've seen so far on KZfaq! Well done!!!

Really cool! Thanks for sharing. Really thought it was building up to a big explosion at the end, was a little disappointed haha

Love this. Cool concept and beautiful results.

I really like the hexagonal surface waves when the ball was oscillating

Beautiful! Nice idea of coloring in function of the velocity and stress

This is outstanding!! Thanks for posting!

This is really really cool! Amazing what bugs can do if you embrace them.

This reminds me of my experiments with Algodoo.. I wish I could program simply so I could make my own simulators; not only to break limitations of Algodoo and visualize better, but to increase performance, as algodoo simulates many things that I often intentionally reduce to 0 (thus disabling them; but its still simulating the calculations; they're just multiplied by 0 in the end), and getting rid of those unnecessary calculations would be nice.

I once had a small, broken lennard-jones simulation that kind of looked like a dbz fight, but this is at another level : ) I'll check the repo when it comes out, but what method did you use for the movement?

It really looks like a star, balancing gravity and internal pressure. Also love that Tubular Bell tune

I love that the particles form to become this little star-like ball that ends up exploding/semi-exploding into a supernova

This looks amazing!

Wow, it's like magic! So stunning!

Wow, looks impressive. Could watch it for hours.

Im glad im not the only one who noticed the resemblance to the way stars work. we are in a simulation for real

1:16 My man simulated a super nova in his hello world xD

Inspiring! Would be interesting to see with additive shading - usually works best with very low RGB values per particle, and just a smidgen of desaturation, so not purely primary colors. Though often requires quite small particles, a good deal of overlap, and very high count (millions), for smooth effects.

Omg this is so amasing!!! I would be also amasing to see collide two heap particles each other with no speed or pressure visualization but rather with acceleration visualization. Acceleration visualization I mean by sum of all the acceleration vectors what effecting a particle. Keep in mind that the acceleration vector length can change very rapidly, so if you visualize it, it can create some crazy flickering, so it would be also amasing to see if you implement it in a way that the particles color changes not just by their current acceleration vector lengt, but how much time the particle experiencing a given acceleration. Like if they being" heating up" when experiencing a great amount of acceleration and that "charge" being dissipating slowly by time. Please try to create something like this it would be amasing to see it.

Incredibly marvellous! If only all the bugs could result in such things...

the 42.0,0.01,1.00,0.02 simulation was probably the coolest thing I’ve ever seen. I need it as a screensaver

this is better then any video-synth I have seen so far

THIS IS INCREDIBLE! 💥

I was expecting a bunch of praying mantis's stuck to a frame, but this also is good.

you've got to do some1-2 hour compilations of animations like this. phenomenal!

This is so mesmerizing!

5:28 you just made a star

Can't wait for the girhub repo, I wanna play with this also. Great video

Bruh your channel is actually amazing. I subbed

To echo what others have said this looks like a stellar simulation. The energy released at the core of a star is constantly pushing outward trying to tear the star apart, but the mass of the star and resulting space time distortion that it creates (i.e. gravity) is simultaneously trying the crush the core into a smaller more compact state. Eventually the two forces reach a balance called "hydrostatic equilibrium" where the outward force is equal to the inward pressure. Amazing that this was created via bug.

These look like real explosion simulations that you'd see in a movie. It's so awesome!

We need an hour compilation of this. PLEASE

This is gorgeous!

Now I want to write a 3d version of this but with a controlled trigger modelled after fusion instead of the overshoot.

This was breathtaking

That looks amazing!

Well done! It probably would be great to see some of the parameters being controlled by the velocity (and maybe pitch and pan, or something) of music.

This is fascinating to me (I just found this channel and am binging through it now). This simulation uses a linear force law (which arguably makes "physical" sense in a 2d simulation), but I wanted to try an inverse square law. If you do that (changing a single line in the code), you get much less spectacular results, the particles settle nicely in a clump, but you do still get occasional eruptions from the core, these go into random directions much like solar flares, and they create shock waves, sometimes resulting in secondary eruptions.

Truly beautiful!

This would make a kickass screensaver

Nice :D This could make a very satisfying audio visualiser.

This guy make a virtual firework, or the star death simulation, using a bug. Just incredible! Don't be afraid to make mistakes, kids. Learn how to turn them into greater things.

I legit was expecting some slow-mo bug splats on a windshield with color effects added in lol!

Just beatiful!

Best screensaver ever!

This is beautiful!

This is amazing! Please make a 1h video of this!!!

This is magnificent

dude, you should totally use newton's gravity laws and make them attracted to eachother instead of the center. it would make a similar but much better effect. plus it would basically be the big bang when it explodes. amazing video!

the fact this models some aspects of atomic physics and fission reactions is amazing.

I've managed to get similar results in the past, though on a much smaller scale, and I think there's something really beautiful about systems that oscillate between chaos and order. It kinda reminds me of life and death. A clump of particles explodes and gives way for others to form and so on forever.

look like a (very)speedlapse of an eternal big bang cycle, maybe this bug art explain our universe

I feel like you're kinda simulating a cosmic event, y'know gravity, explosions and stuff. Also looks like a defeated Final Fantasy boss 😆

what a wonderful screensaver

Very interesting how it forms hexagons after bursting out, you can see it many times around 4:43 through 5:08 If I had to guess why, it is because the spheres are crystallizing into a hexagonal lattice, and drawing a line through opposite vertices of the hexagon corresponds to the close-packed (highest density of atoms in a straight line) crystallographic direction before the explosion. In the close-packed direction of a crystal, the atoms are closer together, so compressive stress is higher in those directions. The explosion would happen along the close-packed directions before any other direction, and that leads to those atoms being farther out in hexagonal close-packed directions because they got a head start. Alternatively, you can think of it as the pressure equalizing in that direction through an increase in volume. As evidence of crystallization in your video, you can see a hexagonal lattice in the small-scale simulations (0:12 through 1:01). You can even see vacancies and dislocations (crystallographic defects) at 1:12. A really good video to illustrate those defects is by Alpha Phoenix, here: kzfaq.info/get/bejne/qdRhjJmrrrmdYZs.html Or you can watch this video from the 50s by a nobel prize winner, which is the original experiment Alpha Phoenix replicated: kzfaq.info/get/bejne/i6tyZpxez9LRlKs.html I've got a background in materials science, had to put in my two cents because the bubble experiment is ubiquitous in the field and this video gave me strong deja vu! You made a great demo

looks amazing

That looks soo cool!

This is beautiful, I've been staring at this for hours

You fing created a whole functioning star ... I don't have words

this is so beautiful! 🤩🤩

This would be awesome as a wallpaper

I was hypnotized.

Congrats! You've just re-created the big bang.

This is incredible:) thanks

Astonishing like always

It’s beautiful! Also, congratulations on finding a new way to punish the KZfaq compression algorithm!

Its looks so nice

I love lt, super relaxing. Its looks like a nebula

wow! That's wonderful

The patterns immediately after the explosions are very feathery and surprisingly organic.

this is my favorite thin on the internet now

this is an amazing fireworks show 👍

Well done on making a star

Gorgeous, that's how selestial bodys are created!

This is brilliant

It's like a much, much more resource intensive windows screensaver you'd stare at for ages as a kid

I suggest instead of making the center the main attraction point, make every particle have a little attraction force

accurate representation of a star, the core is where the fusion takes place and that keeps the star from collapsing, meanwhile, the gravity keeps the star held together
