# Nodegraph

Nodegraph is the user interface where you can **create a logic-based pipeline for node-based compositing inside your Engine(s)**. 

RealityHub visualizes all your Engine function/parameters as a dynamic node inside the Nodegraph Canvas. 

Nodegraph also creates representations of your **I/O** and **tracking** configurations as nodes and allows you to integrate them into your pipeline.
