I think you're both missing the point of how these screens work. Fundamentally they're no different to any other stereo visualization system. For each pixel you display an independent intensity to each eye (ignore color for now, you just apply the same technique to each of the RGB components). The difference is that while many systems have two independent image sources and arrange for only one of them to be seen by each eye (either via fixed polarisation, or shuttered time multiplexing), the iZ3D system takes a single base image and uses a per-pixel filter to control how much of that pixel intensity goes to each eye. You get full resolution, no grainyness or gaps, full color. The only limitation is that you loose some of the peak intensity. However in my experience modern LCDs have more than enough brightness to spare, so that's easily compensated for under normal conditions. Consider three extremes: - If both eyes want to see a black pixel you just tune of the base element. - If both eyes want to see a white pixel you crank up the base element to double brightness, and set the polarising filter half way so that each eye sees a normal brightness white pixel. - If the left eye want to see white and the right black then set the base pixel to normal brightness and polarising filter to block out the right eye. Transforming from separate components (as required by conventional stereo systems and generated from the 3D rasterisation) to an intensity+filter angle (required by the iZ3D screen) isn't conceptually hard. It's basically the same as converting a complex number from cartesian to polar form.
