# Optitrack Calibration Overview

Grid Studio provides the tool to calibration a set of Optitrack cameras and directly receive tracking data from direct communication with the cameras.

The main process utilizes the Optitrack Volume object in Grid Studio. It provides the tools to calibrate the placement of the Optitrack cameras and also handles the conversion of the camera feeds into tracking data.
