Tiled-Display Wall

This 11' x 8' device was assembled for the purpose of allowing scientific investigations of high-resolution images by teams of scientists working in a comfortable setting. In addition, it has proven to be ideal for some of our efforts in urban planning. The tiled-display wall is back-projected by 20 NEC LT158 Projectors arranged in a matrix 5 across and 4 high providing 15.7 Megapixels of resolution. The 20 projectors are driven by:

  • 20 GamePC Workstations each containing:
    • Dual Intel(R) Pentium(R) D CPU 2.66GHz
    • NVIDIA GeForce 6600 video card
  • Head node of the tiled-display wall contains 4 GenuineIntel Intel(R) Pentium(R) D CPU @ 3.40GHz
  • Workstations are interconnected with Myrinet2000

Passive Stereo Display

The VisDuo is a ceiling mounted, 2 projector, passive stereo display, used for viewing complex 3D environments, molecular structures, and medical simulations. The stereo effect is realized by each projector producing images for one eye. The output is polarized by special filters and the resulting image is viewed on a custom polarization preserving screen. Users can view the resulting 3D imagery by wearing lightweight polarizing glasses. This system is powered by a custom workstation with a 3.4 GHz Intel Xeon Processor, 2 GB of RAM and an NVidia Geforce 7800 GTX graphics card.

Access Grid Node

This system enable large-scale remote collaborations using numerous audio and video signals, while exploiting the University's Internet2/Abilene connection. Numerous sessions have been held to date, including workshops in parallel computing, conferences/workshops in computational Chemistry and Bioinformatics, and meetings with funding agencies. The site can currently serve about a dozen participants. For details on scheduling/using CCR's Access Grid please visit the Access Grid page. CCR's Access Grid system consists of:

3 Dell workstations of various configurations (both hardware and software) managing:

  • 4 Sony EVI-D30 cameras
  • 6 Crown PCC 160 Microphones
  • 2 Shure wireless microphones
  • 2 Gentner 1029A wall mounted speakers
  • 3 ceiling mounted Epson 820P projectors
  • Local audio captured by 1 of 4 SoundBlaster PCI cards
  • Audio impedence performed by an ATI Matchmaker unit
  • Audio and telco mixing performed with a Gentner (now ClearOne) XAP800 and XAPTH2
  • Video capture performed using 4 Hauppauge WinTV-dbx cards
  • Display of images is performed using both Matrox dual-head AGP-4x and Matrox dual-head PCI cards
  • Three 100 Mbps ethernet connections through a 1Gbps uplink to NYSERNet and then to the Internet2/Abilene backbone

SGI Onyx300

The high-end SGI Onyx300 visualization system has been the system of choice for CCR's detailed work in urban planning.
The Center maintains an SGI Onyx300 InfiniteReality Single-Rack System with the following characteristics:

  • 10 R14000 processors running at 500MHz.
  • 5 GB of RAM
  • 164 GB of disk space
  • 2 Raster Managers
  • 2 InfiniteReality4 Graphics Pipelines
  • 1 GB of texture memory per pipe
