I Made a 3D Engine in 1 Day (WebGL/JavaScript)

I just tried to code a 3d engine using webgl and JavaScript in one day (24 hours), completely from scratch. It's been a lonnngggg time since I did any serious graphics work as a programmer, and even longer since I touched opengl. This was a bit of a jump-into-the-deep-end project to see if I could crank out a deferred lighting demo in a short time using webgl. In the video I cover all parts of the project, starting with the initial plan, a super general overview on how 3d engines are often structured, and then stepping through the development of the code. By the end you should understand the basics of how a light prepass renderer works and how to implement one using pure webgl.

What was covered:
3D Engine Design Considerations
Materials/Shaders/Drawables/Cameras
Vertex/Fragment shader implementations
Framebuffer Objects
Floating point textures
Other buzzwords

Full source code for the project is available, I mean it's crap but knock yourself out.

There's been a bunch of similar challenges, mostly around making a game in a short time so I thought I'd give it a try but with my own spin. Here are some other videos that helped inspire.
