Direct Light Integration using MIS

For all time I couldn't fully understand how MIS actually works and finally I found enough time to think about MIS more deeply to make things totally clear.
So, from my opinion, things always is little bit unclear until actual implementation :)

Here is my shader on shadertoy:

thanks guys! :) :) :)
Yeah, shadertoy is really good place to do some small experiments and share with community.
I will find more time to make code more small, readable and easy to understand.

This is precisely what I'll use to demonstrate MIS the next semester. Great stuff indeed, thanks!

Yeah, I showed this to my students and I think It is more clear to understand concept and basic idea of method, when you have small, lightweight, easy, real-time demo with full source code.

since then I updated it slightly changed phong with blinn, added stratified sampling, labels and more, refactored some stuff to make it more readable :)

Small typo in the code: search for salmpleLight.
