A stereoscopy.com article reports eight F20 sx DLP® projectors from projectiondesign with built-in Infitec(tm) filters are used in an immersive and interactive 3D stereoscopic computer aided virtual environment (CAVE) visualisation system named Four Space 110. From the article: "Operational since February 2008, the system was designed by Frankfurt-based systems integrator 3Dims GmbH and is situated at the Human Machine Communication Centre at the Munich University of Technology in Germany.
The Four Space 110 CAVE allows the researcher to be completely immersed in the application with surrounding walls, floor and a ceiling and has a wide viewing angle of 110 degrees. "The CAVE is best way to explore three-dimensional data and being both immersive and interactive it helps students and researchers studying human-machine interaction and communication. It has very practical applications in joint projects with a host of industry disciplines, including car manufacturing and design, human interaction with machines, 3D electronic modelling, oil and gas exploration, medicine and architecture" says Friedhelm Birk, Managing Director of 3Dims GmbH.
In the CAVE, the eight F20 sx projectors are fitted with Infitec(tm) stereoscopic channel filters for the reproduction of twelve million pixel 3D images and are integrated with a Fujitsu Siemens Celcius Workstation, powerful nVida graphic cards and IC:IDO immersive software.
The intuitive control is managed by six optical ART tracking cameras, which track and map core head and hand positions using x, y and z coordinates. These coordinates are then fed back into the graphics cluster and the scene is calculated for exactly where the subject is looking for analysis. The environment is also immersive and unlike a flat or curved 3D screen where you have a single display and a limited field of view, in the 110 degree CAVE it's possible for the subject to turn around and see right, left, up, down and behind. The CAVE itself is two-and-a-half metres high, five metres wide and three metres deep. Behind the CAVE are mirrors and the racks which house tracking systems and other hardware.
projectiondesign's Marketing & Communication Manager, Anders Løkke says the company's projectors more than meet the CAVE's imaging demands: "Our F20 sx projectiors with built-in Infitec filters help to provide best presentation of graphical data combined the image quality and accuracy which is required for 3D stereo visual immersion and interaction. These elements combine to enable researchers to better understand and interpret the interaction between humans and machines."
Mr Ablassmeier at the Human Machine Communication Centre at the Munich University of Technology adds, "We were looking for new innovative ways to explore new ways of human interaction and our new system from 3Dims delivered best imaging solution to our highest satisfaction.""
