This electronic gallery at the Krannert Art Museum was a three-walled immersive space using circularly polarized passive stereo technology driven by a pc cluster. Connected to the Internet with gigabit networking, this space was used by artists to develop stand-alone or collaborative art projects in real-time and to display curated exhibits, the first of which, CalculArt, ended in 2006. The second exhibit titled Imag(in)ing Nature ended in 2009. The most recent exhibit titled Astronomic! ended on January 9, 2011.
A portable version of the CANVAS, this system can be rapidly deployed in large gallery spaces, conferences and symposia.
Large vertical wall displays – ImmersaDesks™
The ISL houses five 4’x6’ vertical immersive displays. They support monocular and stereo vision, head, eye, and hand tracking, and incorporate surround sound speaker systems. Two of the displays are portable and are appropriate resources for demonstrating technologies at symposia and workshops.
Horizontal display – Horizontal ImmersaDesk™
The 4’x6’ horizontal immersive environment is appropriate for “sand table” style applications. Typically driven by a small pc cluster, monolithic deskside graphics supercomputers are also used in visualizations requiring large active memory accessed by several processors, such a the visible human dataset. This system is designed for convenient shipping and quick-reinstallation.
- Custom 6-pc rack cluster, each 8-core cpu mated to an nVidia FX5800 graphics module
- 16-core custom pc with nVidiaQuadroPlex integrated graphics unit
- 2 SGI multi-rack Onyx and Onyx2 systems, each with three Infinite Reality graphics pipes and 24 processors; capable of driving the 6-surfaced Cube and 4-sided CAVE™ rooms for legacy applications
- Two SGI deskside Onyx2 systems, 3 single-rack Onyx and one SGI deskside Onyx, again for legacy applications
- Several heterogeneous Linux/Windows clusters designed to support distributed graphics, some dedicated to established virtual environments and some deployable on a project by project basis.
- Over 120 terabytes of RAID-protected storage on-site and in a secure off-site location.
- 10Gb network building backbone connected to 10Gb campus backbone with two dedicated 96 port 10/100/1000Mb Cisco switches, dedicated and white-list protected full subnet (130.126.127.xx) connecting all equipment and computer lab spaces and extending to all ISL office rooms. Additional gigabit LAN switches interconnect each of the several virtual environment systems, providing dedicated graphics-data communications channels through multiple network interface card-enabled computers. DHCP secondary network for non-essential/visitor machines.

- 802.11a,b,g,pre-n wireless networking
The ISL has a full-time secretary, three full-time systems/application programmers, a full-time electronics technician and access to a 2000 square foot in-house mechanical/electrical shop facility. Housed in a 14,000 square foot facility, the ISL is able to add/modify simulator environments to suit the particular research needs of a project while maintaining extant facilities for ongoing research.
