This is a series of lessons or tutorials about WebGL.
Unlike most WebGL lessons these are not based off of OpenGL. OpenGL is 20 years old. The lessons of OpenGL don't match well with WebGL. The APIs have changed too much. The ideas of OpenGL and OpenGL tutorials are out of date with WebGL, OpenGL ES 2.0 and the land of shaders.
I would argue that WebGL is actually a very simple API. What makes it appear complicated is the way in which it's used. The complications are added by the programmer. WebGL itself is simple.
These lessons try to show that simplicity and well as teach the fundamentals of 2D math and 3D math so readers can hopefully have an easier time writing their own WebGL programs and understanding the complexity that other programmers pile on top of simple WebGL.
This is work in progress. Feel free to contribute.
