## What is the Scriptable Render Pipeline

The Scriptable Render Pipeline (SRP) is a feature that gives you full control over Unity's render pipeline and provides the tools you need to create modern, high-fidelity graphics in Unity.

SRP allows you to write C# scripts to control the way Unity renders each frame. Exposing the render pipeline to you in C# makes Unity less of a “black box” when it comes to rendering. Unlike the original built-in render pipeline, SRP allows you to see and control exactly what happens during the rendering process. 

Unity provides you with two prebuilt Scriptable Render Pipelines which you can use in your Projector as a base for your own custom SRP:
* The Lightweight Render Pipeline (LWRP) offers graphics that scale from mobile platforms to higher-end consoles and PCs.
* The High Definition Render Pipeline (HDRP) utilizes physically-based lighting techniques to offer high-fidelity graphics to target modern, Compute Shader compatible, platforms.

Rather than developing your own SRP from scratch, you can use either of these prebuilt SRPs as a base to modify and adapt to your own requirements.
