Rendering 7: Shadows

http://catlikecoding.com/unity/tutorials/rendering/part-7/

It has been very sunny weather lately. I had to look for the shade, so I could write this tutorial.

Shadows complicate the rendering process a lot. In this tutorial, we'll first investigate the work needed to render shadows for directional lights. Then we'll add support for such shadows to our own shader. Once that's done, we'll move on to spotlights and directional lights.
