Da-Lite 3D Virtual Grey Screen
One of the big themes are CEDIA this year was 3D, and Da-Lite was in the thick of it with a new screen material called 3D Virtual Grey (though I would have used the American spelling "Gray"). Designed for 3D applications, the material is said to retain 99% of the incident light's polarization, which is the key to achieving a good 3D effect using polarized light and passive glasses. The demo looked quite good, smoother than most I've seen, which could be due in part to the fact that the real-life material was shot stereoscopically with two cameras and the CGI was created specifically for 3D.
