At this year's SIGGRAPH (Special Interest Group on Computer Graphics and Imagery) conference, a group of researchers achieved stunning 3D image display through 216 projectors.
At the conference, the R&D team of the University of Southern California's Institute of Innovation and Technology demonstrated its own 3D display technology, which basically works by producing a 3D model of a person through video. First, they use 30 cameras to capture video of a person under bright light, then slice the images and display them on 216 projectors.
These projectors surround the display in a semicircle, allowing viewers' eyes to smoothly transition between projected images as they move around the display. In this way, you can see 3D images with natural scenes and rich details.
Due to its high degree of realism, this technology is currently being used in museums and education to create full-size "digital portraits." With the help of speech recognition technology, these virtual characters can also answer questions from the audience.
