ICWall Tiled display for Education and Visualization vrije Universiteit Hans Spoelder, Luc Renambot, Henri Bal, Desmond Germans, Tom van der Schaaf Partners in the MultiVla project SURF IT Innovation in Education Vrije Universiteit Division of Physics and Astronomy Division of Mathematics and Computer Science Universiteit Twente Dinkel (Development Institute for Knowledge, Education and Learning) Objectives (VU) Create a large display infrastructure, suitable for: Education (classroom) Modern scientific applications that need to visualize large data-sets Interactive Virtual Reality applications Develop applications for MNW and BMT Create programming environment for collaborative work ICWall: an "off-the-shelf" video wall High-end graphics is very expensive Use tiled display with many projectors Use standard (inexpensive) components PCs, graphic and network cards 'PowerPoint' video projectors (~ 1 kg) Similar idea as cluster computing, but applied to graphics Setup 4x2 projectors 1024x768 pixels (4096x1536 total) Screen Back-projection, ~5.5m x 2m PC cluster 8 nodes + 1 server Myrinet network Dual AMD Athlons Nvidia GeForce 3 Making a single image Problems Mechanical alignment of projectors is difficult Projectors have different colors, brightness, etc. Solution Project test image Observe image with a camera Analyse difference between original and observed image Compensate for differences in software User perspectives Show multiple information sources simultaneously Slides, images, animations High-resolution interactive visualization, e.g.: Laser diodes (Physics) Root canal (ACTA) Human hearth (Medicine) Height maps (Geology) Gait cycle (Human movement) Near future: Tele-learning over the Access Grid 3D stereoscopic view User interface Much standard software available: Powerpoint, media player, web browser, acrobat reader, OpenDX ... Windows and Linux desktop interface are available User will get Web interface to Upload files to the ICWall Position windows on the screen Our to-do list Turn S1.11 into an Access Grid node Teleconferencing over Internet 3D stereoscopic view (depth) 2 projectors (left/right eye) per tile Better interaction Smartboard, wireless network, user tracking Research in visualization Parallel rendering, computational steering, remote collaboration Plans for using the ICWall Education MultiVla project: MNW (Medical Life Sciences) OKF project: all other VU-FEW programs (about 15 courses) Presentations/Teleconferencing/PR SCHOMS conference (18 April) Surf/Gigaport seminar: the Grid explained (12 June) Nauta lectures prof. Folkers, ETH Zurich (21-28 June) Credits Credits Surf Faculty of Sciences Mechanical Workshop Electronic Workshop VU estate and facility management More information http://www.icwall.org Inauguration, Last Friday
