![]() ![]() Using the Output Mapping tool, these separate viewports are then mapped into different areas of a large 2D canvas, referred to as the application window. With this option, you run a single instance of Unreal Engine per computer, but you set it up to render multiple views of the scene's 3D space. One application instance and host computer per multiple display devices. Each of these secondary nodes drives one or more display projectors. The network also contains several other PCs that run other instances of the Unreal Engine Project. This primary node accepts input into the system from a VRPN server, which relays signals that come from spatial tracking devices and other controller devices. Like all nDisplay networks, one of its PCs acts as the primary node. The image above shows a possible nDisplay network. The primary node is also responsible for accepting input from spatial trackers and controllers through connections to Virtual-Reality Peripheral Networks (VRPNs) through Live Link, and replicating that input to all other connected computers. By setting up these viewports so that their location in the 3D world matches the physical locations of the screens or projected surfaces in the real world, you give viewers the illusion of being present and immersed in the virtual world. Every nDisplay setup has a single primary computer, and any number of additional computers, called secondary nodes.Įach computer in the network runs one or more instances of your Unreal project either in -game or in packaged format.Įach Unreal Engine instance handles rendering to one or more display devices, such as screens, LED displays, or projectors.įor each display device an instance of Unreal Engine handles, it renders a viewport that shares the same view origin or viewpoint. ![]()
