This happens on the sub-pixel level for each of red, green and blue. If it should be visible to both equally, the light is polarized to 90 degrees. If a pixel should be visible to the right eye, the front panel polarizes it to 45 degrees, if it should be visible to the left eye, 135 degrees.

It is up to the iZ3D driver to display the rendered image for the right eye and the rendered image for the left eye, and then use their polarizing LCD panel to determine how much of each pixel from the back screen either eye is supposed to see. The iZ3D monitor has the capability of polarizing light at any angle, and the glasses they use have the right lens set at 45 degrees and the left lens set at 135 degrees.

At in between angles, a proportional amount of light is filtered out. These filters allow light to pass through if they are lined up, but completely block light that is at a 90 degree angle to the direction of the filter. Filters can be used to either allow polarized light to pass through or to block it out. Polarized light all moves in waves rolling in the same orientation. Polarization has to do with the way the light moves as a wave. There is a back screen and a front screen, with the back screen controlling the color and brightness of the pixels and the front screen controlling the polarization of the light coming through. The iZ3D monitor actually has two overlaid LCD panels. On the other hand iZ3D makes use of a whole other technology to build its monitors in a way to display stereo images. The 120Hz LCD panels aren't special beyond the fact that that they can actually display a higher refresh rate than 60Hz panels. While NVIDIA's technology requires a fast monitor, it doesn't require a truly "special" monitor. Before we get into that, let's talk about what iZ3D is actually doing to achieve their stereo effect. Both approaches require that games do a better job of accommodating stereoscopic viewing, but even disregarding resulting anomalies there are some issues we have that really get in the way. But there are just a few drawbacks that make it really hard for us to like iZ3D as much as we want to. The fact that this solution includes passive glasses that don't require any line of sight with a transmitter and never need to be charged along with the ability to use ATI graphics cards made us really want to like this solution. This broad range of compatibility gives them a clear advantage in terms of the potential market and end user options. Additionally, iZ3D's solution will work with any video card that can do 3D graphics (including not only ATI, but Intel and S3). This is different than NVIDIA's technology which makes use of active glasses for viewing a regular CRT monitor or LCD panel (although the monitor needs to be capable of 120Hz for it to look right). The 22" monitor package they sent us to test comes in at $400. Most recently, iZ3D has introduced a stereoscopic viewing system that makes use of an actively polarized monitor and passive glasses in order to bring simple and easy to use stereoscopic viewing to the masses without the color distortion associated with anaglyph.

Their drivers can enable stereo viewing on any PC through anaglyph (the red and blue tinted images we are all familiar with) in addition to working with various other technologies like stereo projectors.

And the other major drawback to NVIDIA's technology is that it only works with NVIDIA graphics cards.Īt GDC we had the opportunity to check out the latest from iZ3D, a company that has been making stereoscopic drivers for quite a while now. But, as we saw with Left 4 Dead, when the game doesn't do too many things that get in the way of the stereo effect, the experience can add a feeling of realism that it is simply impossible to achieve otherwise. Our feelings were a little mixed on the technology, as it isn't always seamless on top of a few other small issues. Earlier this year we had the opportunity to check out a new stereoscopic viewing system from NVIDIA called GeForce 3D Vision.
