Unity SRP Playground

What is this About?

This is a playground for learning and experimenting the capability of Unity's Scriptable Rendering Pipeline. The goal of this project is to research and investigate how computer graphic theories about real-time rendering can work seamlessly in mordern commerical game engines like Unity3D. In current stage, codes are originated from https://catlikecoding.com/unity/tutorials/custom-srp/ in recognition of author's credit.
