Thought this was using three.js, but they built their own physics engine: https://github.com/saharan/OimoPhysics
Sometimes I wonder what I'm missing out by looking at lists curated by points given out by people who come together by hyper specialised interests. Should have heard of it before hearing about the millionth JS framework.
But human curation costs money, and can't (yet!!11~ scream the AI folks) be replaced by AI, so here we are.
Haxe is interesting. I remember coming across it back in the days of Flash.
They also had a bytecode VM of their own called Neko.
At the time when I heard of it there were three platforms you could target with Haxe: JavaScript, Flash, and Neko.
It’s pretty cool to see that after all these years Haxe is still alive and in use.
Had to use it at a gaming startup. Everybody hated it, including the CEO, and we were planning moving to Unity as soon as possible.
Also, I don't believe that the bubble toy is related to their physics engine; it seems like a different type of physics. The engine is focused on 3D collisions, joints, springs, etc., whereas the bubble toy is simulating thin films.
I wish there was source code for the bubble toy so we could see how it works!
Old Version Written in ActionScript 3.0 Supports spheres and boxes as collision shapes Supports various joints (ball and socket, distance, hinge, prismatic, etc...) Fast and stable collision solver
For context: Haxe is a programming language with the main purpose to have several compile targets for many programming languages.
Glad it is working for them.
