# Light Tracking

The goal for Light Tracking is to calibrate the position and orientation of light fixtures and thus allowing Grid Studio to control the pan and tilt values to track an object in space.

## System Design / DMX Merge <a href="#system-design-dmx-merge" id="system-design-dmx-merge"></a>

There are multiple ways that Grid Studio can control a light fixture with or without a lighting desk involved in the system. Click [here](/grid/light-tracking/dmx-merge.md) to find out more the different options.

## Prerequisites: <a href="#prerequisites" id="prerequisites"></a>

Please prepare the following objects and they are added in the Grid Studio project

* ​Fixture Profile​
* ​Tracking Light Fixture​
* ​Measurement Point​
* ​IO Connection for DMX patching​

## Setup: <a href="#setup" id="setup"></a>

* ​[Setup tracking light fixtures​](/grid/light-tracking/setup-tracking-light-fixture.md)
* ​[Define measurement points​](/grid/light-tracking/define-measurement-points.md)
* [​DMX patch​](/grid/light-tracking/dmx-patch.md)

## Calibration <a href="#calibration" id="calibration"></a>

* Calibration with incoming DMX vaues

OR

* Calibration with self-generated values
