VR-arena
Contributors
Overview
The VR-arena is a flat, rear-projected stereoscopic visualization environment for immersive presentations, collaborative reviews, and real-time visualization applications. The projection surface is a Stewart Filmscreen Aeroview 100 screen measuring 6691 x 1930 mm, or approximately 12.9 square meters.
The image is produced by three Barco F90-4K13 projectors. Each projector renders at a native resolution of 2500 x 1600 pixels, and each image is reflected through an individual mirror before it reaches the projection screen. Together, the projectors provide approximately 5592 x 1600 unique pixels across the full display surface. The audio system is a BOSE 5.1 sound system.

Software and Integration
The VR-arena is designed for multiple source and cluster workflows. The current stereoscopic signal path is driven by single node computers running multiple NVIDIA GPU:s, while the projection system is also prepared for an additional source cluster connected through DisplayPort matrices. That architecture makes it possible to switch between different rendering and playback systems while keeping projector-side calibration in Barco Pulse.
The arena is connected to the same immersive software ecosystem as the dome, including C-Play for synchronized media playback and OpenSpace, Unreal Engine applications etc for interactive scientific visualization.
The most powerful computer run 2 x NVIDIA RTX 6000 Ada (48 GB) cards, with 6 x DP (2560x1600) outputs.
