To use UDP for SHM
1. Go to the Configuring Viz.
2. Click on Communication.
3. Click on the Shared Memory tab.
4. In the Shared Memory panel set these parameters:
• UDP Port: Vizrt does not recommend a specific port. Always make sure that
the selected port is not in use by any other program on the same subnet.
5. Click Save.
The syntax for sending key-value pairs is the same as for TCP and UDP Synchronization.

9.1.3 Plugin API
An option to manipulate data in SHM is by a plugin interface.
A use case would be where a TCP or UDP connection can not be used, or is not to be
used. It is possible to write a plugin to import data (e.g. from an XML file, another
database, etc.) and push it to SHM.
Another use case would be an interactive Scene (see 9.2 Internal Data (Interactive
Scene)).
Note: The Plugin API is documented in the plugin API documentation and
comes with the Viz installer (go to, Start -> All Programs -> vizrt -> Viz 3.x -
> Documentation -> Plugin SDK Documentation -> Classes -> Class LIst ->
Shared_Memory).
