Rather confusing that this is seemingly completely unrelated to three.js

[Trigg3r]

+1, would love to see some kind of IDE for three.js!

I'm building one, called Polygonjs ( https://polygonjs.com/ ), you have a few examples to play with ( https://polygonjs.com/docs/examples ).

It does have https://threejs.org/editor/

Also in the category of web 3D engine scene editors is https://playcanvas.com/
