Where is the extra information stored? You can't magically store two images in a single framebuffer without losing something. IIRC, you could use the front screen as a L/R shutter, and lose half the frame rate (60 Hz refresh becomes 30 Hz). Flicker? Or you could interlace the screen and use one field for L and the other for R and lose half the resolution. Gaps between pixels? With specialized hardware, you could drive the front screen with a single bit. But if you're using a 2nd DVI to drive it you're using a second framebuffer and still losing half the information. With current LCDs, it is the display itself that is the limiting factor (frame rate, resolution) not the framebuffer. Is there an advantage other than using polarized glasses instead of shutter glasses? I suspect that the special double LCD required will cost a lot more than the shutter glasses. It still doesn't solve the headache problem. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
