That's basically done : a lot of samsung LCD monitors are already "stereo compatible" and use this polarization fact. It's not even advertised. I'm not sure though what is the pattern of pixels and what polarization is used (vertical/horizontal, diagonals, circular...). And to answer Giga2, there are indeed passive 3d monitors. Still expensive and not very high resolution though. Cheers -- Nicolas Bonneel http://cs.ubc.ca/~nbonneel/ |
