Unity Shader reference Notes - before everything else ....

https://catlikecoding.com/unity/tutorials/rendering/

There's a very good tutorial I am following, and I suggest everyone who want to learn Unity Shader follows too.

The author goes into very detail into the Unity's rendering structure and what is happening behind a unity function.  Thus it is very good for deep learning.

For intermediate learner this tutorial does not go directly to the point. It is not the quick reference for getting anything done.

The problem of writing shader in Unity or in any shader environment is that, even though you know the theory of how to wring any shader,  the difference between different environment will prevent you doing it quickly. They provide different variable function and do same thing in different ways.

To have a quick reference is supper important for efficiency. And this is the purpose of this series of blog.
