What do you mean by "watch with glasses?" About the only way you can get any 3-D without specialized equipment is to use red/green anaglyph, which doesn't work with color films and causes headaches. Anaglyph had a brief bit of popularity in the fifties for local theatres in the hinterlands that didn't want to install special equipment. It wound up giving 3-D a bad reputation that it still has not overcome.
Anaglyph will kind of work with HD, but with conventional SD systems it doesn't work at all because with NTSC video the resolution of brightly colored objects is very poor, and it's poorer with red than with green. The normal polarized-glasses 3-D systems require some sort of special hardware to make sure that the two color images are presented with different polarization. In the fifties that was usually a matter of two synchronized projectors with a bicycle chain between them, one with a horizontal and one with a vertical polarizer, combined with a special screen that maintained polarization. With video systems today there are similar arrangements. Probably most common these days are systems that use glasses with LCDs in them, so that the eyes flicker on and off alternately and in synch with the picture. This means the picture needs to be shown at very high frame rates but that's no problem in the digital era. --scott _______________________________________________ FrameWorks mailing list [email protected] https://mailman-mail5.webfaction.com/listinfo/frameworks
