The Immersive Cabin

Architectural visualization in the Immersive CabinConformal visualization for Virtual Colonoscopy in the Immersive Cabin

Abstract

We present a visualization and interaction framework for the Immersive Cabin (IC), which is a 5-wall CAVE-like immersive 3D environment. The back-end rendering is provided by a cluster of 5 workstations with 2 NVIDIA Quadro GPUs each. We utilize a pair of projectors for each wall and an external LCD shutter system that is synchronized with active stereo glasses. Each workstation produces a synchronized pair of stereoscopic images for a single wall in the IC. If only one GPU is dedicated to rendering, the second one is utilized as a computational device using C/C++ and the NVIDIA CUDA extensions. In addition to the depth cues and surround immersion from the visualization system, we use wireless optical head and hand tracking to further enhance the data exploration capabilities. Combined with a range of interaction and navigation tools, our system can support a variety of interactive applications, including architectural and automotive pre-visualization, urban planning, medical imaging, and simulation and rendering of physical phenomena.

The RealityDeck

Conceptual rendering of the RealityDeck

Abstract

The human visual system offers superior cognitive bandwidth to all other avenues of sensory input. Visual cues allow for gaining insight from data, either collected or computed. However, we have recently observed an explosion in the size of data sets with no end in sight. Camera sensors produce images of giga-pixel size while petascale supercomputers provide gigabits worth of data for every second of operation.  The current status quo in visualization environments is struggling to accommodate these vast amounts of data. Thus, the need for a contemporary visualization facility that can provide giga-pixel level resolution, enough to appropriately display the data of the future, becomes apparent. To fulfill this role, we are developing the RealityDeck, an Immersive Giga-Pixel Display with more than 1.5 billion pixels worth of resolution, enough to saturate the human eye.
