OSG.JS
ELI5:
osg.js is like a big box of toys that help people make cool things in 3D on the computer. It has all sorts of different tools and shapes that you can use to create different things like buildings, cars, and even whole cities! The people who make these things can also control how the objects move and interact with each other. It's kind of like playing with Legos, but instead of building with physical blocks, you use your computer to make neat 3D things.
