More on the 3D DTI Monitor

Tyana pointed us to a review at Evil3D about the DTI 3D Monitor that we mentioned here not to long ago. They actually sat down and used it a bit and talk about the price ($12k!) the aesthetics (They like it) and play some games (it crashes a lot). This is a really fascinating technology tho: 3D without glasses, and it apparently works really well, assuming you can hold your head still while you play Q3A!

This bit is slightly disappointing.

"When in 3D mode it produces one line of light for every two columns of pixels on the LCD. Imagine that the columns are divided into two groups. One group being the even numbered columns and the other being the odd numbered columns. When you sit directly in front of the display or in certain positions off to the side, your left eye sees these light lines through the odd columns of pixels, while your right eye sees them through the even columns. So, each eye sees only half of the pixels."

Since they are using more or lass standard flat panel LCD's this more or less halves the horizontal resolution. The unfortunate fact here is for stereo imaging you need all the horizontal depth you can get. Since the perceived depth is relative to the horizontal offset of the two images, the dumber of depth steps becomes limited.

The offset between image components is limited to the distance between eyes (this would be perceived as infinite depth), this distance is approximately 3 inches. The resolution (once halved) is about 30 pixels per inch giving a maximum offset of difference of about 90 pixels. The translates to about 90 discrete steps of depth although this can be smoothed of somewhat with anti-aliasing it could really do with some more horizontal resolution. That said, I still want one.
