The purpose of the Feed plug-ins is to receive real-time data and apply it to the state of a Viz Artist Scene in various ways. They are mostly used to create Scenes for use in financial data and stock feed visualizations.

The method of use for the plug-ins is as follows:

1. Identify text geometry, or container visibility in a scene that an external real-time data feed source is to control.

2. Apply the appropriate Feed plug-in to the container of the identified property.

3. In the plug-in properties, specify a data feed key to look for in the incoming data feed.

4. Send UDP messages to carry the content of the data feed in a YAML format which carries key-value pairs to a specific port on the Viz Engine host, which the plug-in infrastructure listens to.

The following container plug-ins are located in the Feed folder:

• Feed Activate

• Hide in Range

• Feed View
