3D Monitors

[Silent_One]

3D images on monitors made bt Sharp. They enev showed how Quake would look like. Would this make 3D viedo cards obsolete? Wish they showed a picture. Maybe someone can find one.

The monitors will let people see high-resolution 3D images or run 3D programs without using special glasses or additional software. For example, bodies and bullets appear to fly all over the place in a version of the popular game "Quake" that has been adjusted to work on Sharp's 3D monitors.

Hehe...there's no "3D acceleration" in the monitor, so it would certainly not make 3D video cards obsolete.

This is about producing an actual 3D image, like you'd think of from a hologram.

The technology in the monitors actually uses from the exact same idea of 3D glasses: show each eye a different image. The monitors display a different image at different angles, such that each eye can get a different picture. You have to be sitting (almost) perfectly still with your head in just the right position to get the effect.

Anyway, since each frame must be rendered twice, from two different angles, the stress on the GPU is quite a bit higher than without the stereo display.

Nappe1:
Read the article Silent_One linked, especially the "3D sandwich" part.

It's two images, but both are displayed (partly) at the same time. The first panel has "pixels" shaped like vertical stripes. These stripes hide pixels in the second panel. But they hide different pixels depending on view angle. So your two eyes sees different pixels, and it's possible to view different images to the two eyes. Then, if you shift the barriers in the first plane, you see other pixels.

Simplified, you set the parallax barrier in one position, and display left image on odd pixels columns, and right image on even pixel columns. Then you shift the barrier, and display left image on even pixels columns, and right image on odd pixel columns. (The real version is quite possibly not that simple, but you get the idea.)

You were too horny to read? Interesting...

I think I've posted this link sometime in the past, but it has a few interactive java applets that help show how the effect works. These demos show how a display with head tracking would work.

Main problem with all 3d systems is lack of vendor driver support. Hello ATI.
