The CAVE is a cube with a side length of 2.7m. The floor is made of a three layer laminated safety glass, covered by a rear projection screen while the walls and ceiling are built of dark plexiglass screens. The images are rear projected at a resolution of 2560x1600 pixels (QXGA Wide) by five Barco F80-Q7 single chip active stereo DLP projectors with separate inputs for both left and right pictures. The large-size and immersive projection encourages users to discuss their datasets with on-site colleagues. Furthermore, it is possible discuss results with worldwide partners in collaborative working environments while looking at the same data.

For the tracking of the viewer's head and hand we use an ART Trackpack optical tracking system.

Visualization Cluster

The CAVE and tiled display are driven by a DALCO Visualization cluster of 34 nodes powered by 11 Intel Xeon CPU E5-2643 0 at 3.3GHz, 11 Intel Xeon Gold 6134 CPU at 3.2GHz and 12 Intel Xeon CPU E5-2670 0 at 2.6GHz. Two head nodes are equipped with 256 GB RAM, the rendering nodes with 128 GB. The cluster is equipped with 22 GPUs, 11 of each P6000 and K6000. A high speed QDR infiniband interconnect provides enough bandwidth for interactive simulations as well as high speed parallel rendering. The cluster is booted via NFS and runs Linux (currently Centos 7.6).

On the software side the CAVE is driven by our COVISE virtual reality front-end called OpenCOVER. This software allows interaction with on-going numerical simulations and post-processing steps mainly in the area of computational fluid dynamics (CFD) and structural mechanics (e.g. crash analysis).
