I saw a 3D-movie in a theme park wearing some cheap transparent glasses. Can this technolgy be used for TV and PC as well?
Yes, but this polarization technique requires a special monitor or a monitor add-on which is considerably more expensive than shutterglasses. Polarization could be added to any LCD-monitor. In mass-production this would raise the cost for such a 3D-LCD-monitor by about $20. Until now no major LCD-manufacturer agreed to add this technology.
