16 Preview Server
This section describes the installation and configuration of the Preview Server.
The Preview Server is a console application setting up an HTTP REST service on

host for the Viz Engine.
IMPORTANT! The Preview Server must be installed on a separate Viz Engine machine
with its own license.
