Bad Apple but it's a Fluid Simulation

I tried rendering Bad Apple inside of a particle-based fluid simulation.
(I recommend watching in 4K if you can, as video compression is not overly friendly towards all the little dots!)

Hey everyone! I was inspired by 'BadAppleBot' (from the recent chess programming contest) to try and run Bad Apple inside of my fluid simulation project. To do this, I've taken the frames from the Bad Apple video and used the Jump-Flooding algorithm to calculate vectors for every frame that go from each pixel to the nearest pixel of the opposite colour. These vectors are then used to accelerate the particles (along with the pressure forces from the fluid sim of course). I recommend watching this in the highest quality you can, because compression will surely turn it to sludge. (You can also find a link to download the full-quality video in the description).

If you'd like to play around with the project, it's currently in early access to Patreon supporters, but will be freely accessible in ~2 weeks.

if it can run code, it runs “Doom”. if it can play sounds, it plays “through the fire and flames”. if it can render, it renders “Bad Apple”. it’s the rule, no exceptions.

I love the part at 1:41
there aren't enough particles for the character's body because of how the fluid got dispersed, but then when she reaches up, more particles flood in and make her outline clearer. Really neat interaction there

Engineers will spend countless hours making a particle based fluid simulation and then use it to make shitposts. Absolutely marvelous

As someone who's had to deal with fluid simulations for the past 17 odd years, I fully appreciate every time the simulation looks like it's exploding from too fast of a state change

The man learned what Bad Apple is (from the chess tournament) and went straight for it lol

2:48 - The single most hydrophobic drop of liquid I have ever seen.

[YHK_YT]

This unironically actually looks amazingly good

[IkethRacing]

New video idea: Take this fluid simulation, add a third dimension, add a few more params to each ball such as temperature, humidity, and pressure, and make a weather predictor. Then take it a step further and graduate to one of the models used to predict hurricane paths.

Sebastian has gone from not quite understanding the meme to making his own version. That's called growth.

0:56 I CANT STOP REWATCHING THAT PART

[staysterling]

Man the "splash" when it goes from dark to fluid is so goddamn pretty, like 0:56 is so 🤩

[cybroxde]

This will inevitably become the most viral video on this channel.
Mark my words.

[pixelchu]

The inevitability principle that anything will be turned to Bad Apple.
This was a trippy experience, especially at 2:21

[AkshayKumarX]

I always laugh out loud whenever I see an insane bad apple video.

A bad apple homage from Sebastian was the last thing that I had on my mind.

God tier.

0:11 it looks like she's blowing the particles away from her mouth

[harveyhans]

THIS LOOKS SO GOOD WHAT THE HELL

ive seen countless iterations of this played over other "screens", but this is the first time ive gotten goosebumps for an entire bad apple video, specially the extra effects i need the lossless videooo

[catty]

3:10 ngl when her hands appeared that was really cool

[FriedMonkey]

This works really well because the bad apple animation is already really fluid

[graceanderson]

The girl splashing the fluid as she dances across the screen at 2:13 is my favorite part
