Rendering, part 1: Matrices

http://catlikecoding.com/unity/tutorials/rendering/part-1/

I announced a tutorial series about shaders, but it's actually more complex than that. Shaders are a big part of Unity's rendering pipeline, but there's more. So I'm doing a series about the whole rendering process.

Here is the first installment. It's about transformations. And those transformations are done with matrices. Now it turns out that many people shy away from matrices, not understanding how they work. This won't do, because you'll need them when writing shaders. This tutorial will introduce matrices as a convenient tool for manipulating space.
