Reverse engineering the rendering of The Witcher 3

Welcome,

This is the index page for my "Reverse engineering the rendering of The Witcher 3" small series where I select some rendering techniques from "The Witcher 3", analyze them using

RenderDoc

, then grab DirectX assembly for shaders and finally try to turn these instructions back to readable HLSL shader.

I focus especially on understanding and explaining presented techniques; it's all for learning purposes after all.

The genesis of the series is simply "I want to know how it's done". Having RenderDoc and other tools which allow us to see every stage of the pipeline is great way to learn how games do rendering stuff.

I have not worked on "The Witcher 3: Wild Hunt" nor its expansion packs in any way so all of code and conclusions here are results of my analysis and tinkering.

I'm the author of HLSLexplorer which greatly helped me in the process of learning HLSL assembly and was invaluable in writing this series. See the

Enjoy! :)
