# Tracking Visualizer

LightAct's *Tracking Visualizer* is a powerful technology that combines location tracking and data visualization. It allows users to map the movements of people or objects and convert this information into captivating visual displays that respond to user interactions in real time.

## Creating a Tracking Visualizer

To place a **Tracking Visualizer** on the *Viewport*, drag its dedicated icon from the toolbar menu and drop it somewhere on the Viewport.

## Tracking Visualizer Properties

You can access the *Tracking Visualizers' Properties* by selecting it on the *Viewport* and opening the *Properties* window.

### General Properties

Under the *General* section, you can rename or manually change the *position* or *rotation* of the *Tracking Visualizer* object. You can also toggle between **visible/hidden** and **locked/unlocked**.

### Content Properties

Under the *Content* section, you can choose your desired **Tracker device** by clicking on it from the *Tracker device* dropdown menu. This menu consists of all Tracker receiver device nodes that have been placed in the *Devices* window.

In our case, we will choose the **BlackTrax receiver** as our *Tracker device*.

**Good to know**: Different technologies use various names for environment trackers. For instance, BlackTrax calls them *Beacons*, while Antilatency uses *Tags* and *Markers*. In LightAct, we simply refer to them as trackers, regardless of the chosen technology.
{% endhint %}

In the *Source* section, by clicking on the **Add tracker** button you can add as many Trackers as you want to visualize in the Viewport.

Under the Trackers column, type the unique *Tracker names*. With the **Show trackers** checkbox under the *Rendering* section enabled you will be able to visualize your tracking environment in LightAct.

{% hint style="info" %}
**Good to know**: For the *trackers* to inherit their correct position, the *Tracking device node* needs to be enabled and correctly receiving data. In the opposite case, the *trackers* will turn red, indicating that there is some kind of an error in obtaining tracking information.
{% endhint %}

### Rendering Properties

In the *Rendering* section, you can toggle between the visibility of different elements in your tracking environment.

In the case of BlackTrax, aside from *Trackers* themselves, you can choose to visualize individual *LEDs* by clicking on the **Show LEDs** checkbox or even see how they're connected by enabling **Show LED connections**.
