Researchers from the University of São Paulo and University of British Columbia reveal what one might describe as a "true" 3D display-- Spheree, a spherical device allowing one to admire and interact with 3D objects.
Described as the first "3D perspective-corrected interactive spherical scalable display," Spheree was revealed at the SIGGRAPH 2014 conference. In another mouthful from the team, it "arranges multiple blended and calibrated mini-projectors to transform a translucent globe into a high-resolution perspective-corrected 3D interactive display."
The researchers add Spheree does not have seams and blind spots, since it uses no special mirrors or lenses. Instead it uses an auto-calibration algorithm dubbed FastFusion to combine the resolution and brightness of the pico-projectors, while a basic webcam provides the positions of each projector's images on the globe.
