K-Cave demonstration: Seismic information visualization system using the OpenCABIN library
Yoshisuke Tateyama, Satoshi Oonuki, So Sato, Tetsuro Ogi · 2008
We demonstrate a VR application running on a i mmersive projection display: K-Cave. We constructed seismic information visualization system using the OpenCABIN library. In this paper we describe the K-Cave hardware configuration, OpenCABIN library and seismic information system. 1. K-Cave: a CAVE at the Keio University The K-Cave is a CAVE-clone VR display system at t he Keio University. It consists of 3 screens, 6 projectors, 3 rendering PCs and a control PC. Binocular parallax is achieved by circular polarization filters in front of each projector and in a pair of glasses. Passive stereo feature does not require special high-end graphic display functions like genlock nor framelock. Dimensions of front and floor screens are 2.6 meters width and 2.1 meters height, and right screen is a square whose sides have length 2.1 meters. Each screen’s pixel resolution is XGA (1024 x 768 pixels). The viewer’s position is tracked by a magnetic position sensor: Ascension technology corporation’s Flock of Birds with an Extended Range Transmitter. PCs are connected via 1000 base TX ethernet and using normal TCP/IP protocols. Each PC runs on the Linux operating system.
