We present a novel immersive workstation environment that scientists can use for 3D data exploration and as their everyday 2D computer monitor. Our implementation is based on an autostereoscopic dynamic parallax barrier 2D/3D display, interactive input devices, and a software infrastructure that allows client/server software modules to couple the workstation to scientists' visualization applications. This paper describes the hardware construction and calibration, software components, and a demonstration of our system in nanoscale materials science exploration.

This video describes the CAVE2 Hybrid Reality Environment developed by the Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago (UIC). CAVE2 is a nearseamless flat-panel-based, surround-screen immersive system that can simultaneously display both 2D and 3D information, providing more flexibility for mixed media applications and more opportunities for groups of researchers to work together with large heterogeneous datasets [1]. CAVE2 is a cylindrical system of 24 feet in diameter and 8 feet tall, and consists of 72 near-seamless, off-axis-optimized passive-stereo LCD panels, creating a 320-degree panoramic environment for displaying information at 37 Megapixels (in stereoscopic 3D) or 74 Megapixels in 2D and at a horizontal visual acuity of 20/20 [2]. Custom LCD panels with shifted polarizers were built so the images in the top and bottom rows of LCDs are optimized for vertical off-center viewing, allowing viewers to come closer to the displays while minimizing ghosting. EVL's Omegalib middleware supports fully immersive OpenGL, OpenSceneGraph and VTK applications, as well as EVL's SAGE middleware to achieve a hybrid 2D/3D environment.
