24-screen Flat Stereo Visualization System

This service ended.

System overview

24-screen Flat Stereo Visualization System is composed of 24 50-inch Full HD (1920x1080) stereo projection module (Barco OLS-521), Image-Processing PC cluster driving visualization processing on 24 screens. A notable feature of this visualization system is that it enables approximately 50 million high-definition stereo display with horizontal 150 degree view angle. Also, it is notable that large-scale and interactive visualization processing becomes possible through the dedicated use of PC cluster for large-scale visualization (VCC).


Furthermore, OptiTrackFlex13, a motion capturing system has been introduced in this visualization system. By making use of the software corresponding to the motion capturing system, interactive visualization leveraging Virtual Reality (VR) becomes possible.


Furthermore, high definition video-conference system (Panasonic KX-VC600) is available.


Node performance

Image Processing PC Cluster on Umemkita (IPC-C) is composed of 7 computing nodes, each of which has two Intel Xeon E5-2640 2.5GHz processors, a 64 GB main memory, 2 TB hard disk (RAID 1), and NVIDIA Quadro K5000. This PC cluster controls visualization processing on 24 screens.
