It communicates and synchronizes information between all the application instances that make up the cluster, ensures all instances render the same frame at the same time, ensures each display device renders the correct frustum of the game world, and more.Ī shared configuration asset that contains all the settings nDisplay needs to start up the correct number of instances on the correct computers, each rendering the right points of view on the game's 3D world to produce the illusion of a seamless rendering across all display screens or projectors. NDisplay adds several components to the usual Unreal system architecture:Ī Plugin that works inside the Unreal Engine. However, all viewports are being rendered by the same instance of Unreal Engine, so you can't benefit from having multiple graphics cards installed on the same computer. In this scenario, the benefit of using nDisplay in conjunction with Mosaic or Surround is that you can render viewports that accurately match the physical arrangements of your different monitors, even when those monitors do not lie along the same plane. You then use a technology such as NVIDIA Mosaic or NVIDIA Surround to split up that single large window and render each separate area on a different display devices. With this option, you run a single instance of your Unreal Engine application on your computer, but you set it up to render multiple separate rectangles of the scene's 3D space into different areas within a large window. One application instance that renders to multiple display devices. Each of these cluster nodes drives one or more display projectors. The network also contains several other PCs that run other instances of the Unreal Engine Project. This master 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 master node. The image above shows a possible nDisplay network. The master node is also responsible for accepting input from spatial trackers and controllers through connections to Virtual-Reality Peripheral Networks (VRPNs), and replicating that input to all other connected computers. By setting up these viewpoints 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 in the virtual world.
