Future science: Using 3D worlds to visualize data
Take a walk through a human brain? Fly over the surface of Mars? Computer scientists at the University of Illinois at Chicago are pushing science fiction closer to reality with a wraparound virtual world where a researcher wearing 3D glasses can do all that and more.
In the system, known as CAVE2, an 8-foot-high screen encircles the viewer 320 degrees. A panorama of images springs from 72 stereoscopic liquid crystal display panels, conveying a dizzying sense of being able to touch what’s not really there.
As far back as 1950, sci-fi author Ray Bradbury imagined a children’s nursery that could make bedtime stories disturbingly real. “Star Trek” fans might remember the holodeck as the virtual playground where the fictional Enterprise crew relaxed in fantasy worlds.
The Illinois computer scientists have more serious matters in mind when they hand visitors 3D glasses and a controller called a “wand.” Scientists in many fields today share a common challenge: How to truly understand overwhelming amounts of data. Jason Leigh, co-inventor of the CAVE2 virtual reality system, believes this technology answers that challenge.
“In the next five years, we anticipate using the CAVE to look at really large-scale data to help scientists make sense of that information. CAVEs are essentially fantastic lenses for bringing data into focus,” Leigh said.
