GooCreate's renderer is based upon ThreeJS, which is a high level library upon of WebGL (which is essentially OpenGL in the browser.)

Actually it's based on our own engine, Goo Engine, also open source: https://github.com/GooTechnologies/goojs

But yeah, still essentially OpenGL in the browser :)

I wrote a bunch of ThreeJS and I see code I wrote in your Goo Engine. You also have the ThreeJS license in your license:

"GooCreate's renderer is based upon ThreeJS". With that I thought you meant that our tool (Goo Create) was built on three.js which it is not. Yes a subset of a few files in the engine contains some code from other open source libraries. Mostly it is a derivative of my previous open source (Java) engines Ardor3D/jMonkeyEngine and new code.

" a subset of a few files in the engine contains some code from other open source libraries"

The code that is ThreeJS derived includes most of the 3D engine classes including:

The main Renderer class (!). As well as the Texture, Camera, RenderTarget, ShaderLib, ShaderBuilder, EventTarget classes. Also the majority of the stuff in the /math, /lights, /pass directories.

GooEngine's renderer (not game engine) was clearly forked from ThreeJS some time ago and diverged (significantly in some places and for the better) but the lineage is clear.

You are right Ben! The rendeder contains a bunch! (Still a subset of the engine like i said)

Hail open source! :)
