Server Controlled Publishing for VRML
When the Visualization server initiates a request to convert VRML data to the Creo View format, the server uses the vrmlworker to convert the file in the background. This Visualization server could be a Windchill server or another customized server environment.
The VRML worker is an important link in achieving the full functionality of the Visualization server. For more information, refer to Visualization Server Definition.
