VRSG as a Multi-Channel Image Generator

MetaVR VRSG™ support for synchronized channels, VRSG MultiChannel, is a series of VRSG applications coupled in such a way as to create a multi-channel image generator. This synchronized channels technology enables users to build high-end visual simulators.

VRSG MultiChannel is a UDP-based network interface that allows your simulation model to control an unlimited number of VRSG channels. The multi-channel synchronization technology is used in a variety of multi-channel simulators ranging from ground vehicles to helicopters and fast-moving fixed-wing aircraft.

Using the VRSG MultiChannel viewpoint protocol, your simulation model provides the current position and orientation of the ownship every frame. The visual channels begin drawing the scene when they receive the current ownship update. This affords what we refer to as “front-end” synchronization, ensuring that each channel begins the next frame at the same time, and remains paced by the host.

You configure the client views in the Client Views tab of the VRSG Dashboard. This tab is available when you use the VRSG multichannel executable. This tab contains the controls that enable you to identify which VRSG clients will be controlled by the master channel and specifies the relative locations and orientations of the client views.
