Have you looked at the new Samsung 3D TV (samsung.com)? If not, go to BestBuy and check one out. My only, no two, no three complaints are:
- The price. Buying the TV is not enough, you also need to buy special glasses AND the blueray DVD player that generates the appropriate 3D picture. A whopping $5000 when all said.
- You need to wear special polarized glasses that are synched with the TV to produce the 3D picture (did I say that it is amazing). Not only do you have the inconvenience of the glasses but you have weight, yup batteries. And for those of you that wear glasses a 2 hr movie might be too much
- Flicker! The refresh rate is not high enough and after a while the flickering might bug you.
However, this post is not about a review of the Samsung tv, but about new 3D technology emerging in the universities.
They are working on projecting light onto controlled falling drops of water. The wall of water drops is layered to produce a natural 3D effect without having to wear glasses – WOW.
PITTSBURGH—AquaLux 3D, a new projection technology developed at Carnegie Mellon University’s Robotics Institute, can target light onto and between individual water droplets, enabling text, video and other moving or still images to be displayed on multiple layers of falling water.
In contrast to existing technologies for projecting images onto water surfaces, AquaLux 3D makes it possible to create three-dimensional images in water by using multiple layers of precisely controlled water droplets, said Srinivasa Narasimhan, associate professor of robotics. By combining the droplets with clouds of mist, it would be possible to create unique 3-D effects for theme parks, exhibitions and interactive games that don’t require special eyeglasses to view, he added.
“The beauty of water drops is that they refract most incident light, so they serve as excellent wide-angle lenses that can be among the brightest elements of an environment,” said Narasimhan, who developed the display with Takeo Kanade, professor of computer science and robotics, and Peter Barnum, a Ph.D. student in robotics. “By carefully generating several layers of drops so that no two drops occupy the same line-of-sight from the projector, we can use each drop as a voxel that can be illuminated to create a 3-D image.”
