So I want to implement a Physically Based Rendering system in my Render Engine but after looking at all of the siggraph presentations online,
I've got to admit I don't understand much due to the fact I'm not that good with math and cannot understand any of the equations in the presentations. I was wondering if someone here could explain how to implement this.
I was reading this article: http://ift.tt/2aEBPWk
Which kinda helped but I still don't understand a lot of it, so I'm downloading the code sample to see how it works.
Pretty much all I understand so far is that I use a BRDF to calculate the amount of Specular and Diffuse light there is and perform a blur on a Cube Map.
Help. Please.
