The High Definition Render Pipeline (HDRP) is a prebuilt Scriptable Render Pipeline, built by Unity. HDRP lets you create cutting-edge, high-fidelity graphics for high-end platforms.
Use HDRP for AAA quality games, automotive demos, architectural applications and anything that requires high-fidelity graphics. HDRP uses physically-based lighting and materials, and supports both forward and deferred renderingThe process of drawing graphics to the screen (or to a render texture). By default, the main camera in Unity renders its view to the screen. More info
See in Glossary. HDRP uses compute shaderA program that runs on the GPU. More info
See in Glossary technology and therefore requires compatible GPU hardware.
