Both smart objects and basic objects define a pattern of markers that Evoke can locate from camera centroid detections.

### Create smart objects

In Evoke, a smart object is the representation of a type of object that has programmable active markers (eg, a Pulsar). Pulsars are smart in that they communicate with the Evoke PC via a Beacon. This enables a Pulsar to set its marker pattern, sync to the Viper cameras and report its battery level back to the PC.

To enable tracking of Pulsars, you must create a smart object in Evoke for each Pulsar that you want to track.

### Create basic objects

A basic object lacks the two-way communication of a smart object (eg, a passive marker plate or a Nova active strand). A Nova is a basic object as its active markers can be either on or off and it has to be controlled manually.

To enable tracking of props, you must create basic objects in Evoke for each prop that you want to track.

### Manage your tracking configuration

When you have finished setting up your smart objects and basic objects, you can save the whole tracking configuration (including all basic and smart objects) in MCP format for future use.

To do this, at the top of the **Tracking** panel, click the **Save tracking configuration** button:

The default location for tracking configuration files is: *C:\Users\Public\Documents\Vicon\Evoke1.x\Tracking*

When you want to re-use your tracking configuration, click the **Load tracking configuration** button to re-load the file.

### Position cameras and Pulsars

With your Evoke system installed and licensed, and after you have created smart objects, you can position the cameras and markers.

1. Position your cameras around the volume, ensuring that two or more cameras can see every point in the volume in which you intend to track motion.
2. Place Pulsars around the floor to outline your volume.
