This paper describes a production-grade software toolkit used for shared multi-model visualization systems developed by the Expanded Perception and Interaction Centre. Our High-End Visualization System (HEVS) can be used as a framework to enable content to be run transparently on a wider range of platforms (Figure 2) with fewer compatibility issues and dependencies on commercial software. Content can be transferred more easily from large screens (including cluster-driven systems) such as CAVE-like platforms, hemispherical domes, and projected cylindrical displays through to multi-wall displays and HMDs such as VRR or AR. This common framework is able to provide a unifying approach to visual analytics and visualizations. In addition to supporting multi-modal displays, multiple platforms can be connected to create multi-user collaborative experiences across remotely located labs. We aim to demonstrate multiple projects developed with HEVS that have been deployed to various multi-modal display devices.
