Water Droplets CAN Create Multilayered Display
MC2 Take Aways from The Story:
Peter Barnum, Srinivasa Narasimhan and Takeo Kanade at Carnegie Mellon University in Pittsburgh, Pennsylvania, have projected images onto a series of water screens, one behind the other, to give depth to the image.
The team used four parallel sets of needles, computer-controlled to release their lines of droplets at slightly different times so the droplets in one vertical layer do not obscure those in the other layers.
"A single projector, by quickly switching between images, can display on different layers at different times," says Barnum. "Anything you can have with a computer, like images, text, movies, or anything interactive, you can have on the drop display."
Barnum's team will present their work at the
annual computer graphics conference SIGGRAPH
in Los Angeles, this month.
