Unity cluster package – dragging and dropping components for multi-projection virtual reality applications based on PC clusters
MetadataShow full item record
Virtual Reality applications created using game engines allow developers to quickly come up with a prototype that runs on a wide variety of systems, achieve high quality graphics, and supportmultiple devices easily. This paper aims to present a component set (Unity ClusterPackage) for the Unity game engine that facilitates the development of immersive and interactive Virtual Reality applications. This drag-and-drop component set allows Unity applications to run on a commodity PC cluster with passive support for stereoscopy, perspective correction according to the user’s viewpoint and access to special servers to provide device-independent features. We present two examples of Unity multi-projection applications running in a mini CAVE (Cave Automatic Virtual Environment)-like (three-screens) system ported using this component set.
