This work demonstrates cross-platform capabilities of Unreal Engine for virtual reality applications, suggesting improved usability across immersive environments.
Virtual Reality (VR) is increasingly being adopted in industry and research. However, VR development is mostly focused on Head-Mounted Displays (HMDs), while another immersive display modality, the CAVE Automatic Virtual Environment (CAVE), receives less attention. Additionally, the development of VR experiences for the two differs widely, and work on deploying VR experiences across platforms like immersive VR HMDs and CAVEs remains underexplored. In this work, we discuss three approaches and present a conceptual pipeline for cross-platform deployment of Unreal Engine-based VR experiences. Specifically, we present the concept for a CAVE-Extended VRTemplate, an extension of Unreal Engine's standard VRTemplate, that shall enable VR applications to run across both HMDs and CAVE environments with minimal modifications. In the future, we aim to evaluate the usability of our framework with expert VR users.
