30 minutes with 3D gaming and you have a headache. Also, you need a really powerful machine for 3D, if you want to enjoy good graphics.
You mean a PS3? If anyone can do it Sony can. I'm not being a fanboy either. They produced a powerful console, they have the perfect set up to try. More so than any other console.
Why?
They have a very powerful and now affordable console with a good base, they have the biggest disc size, they run using HD components, all PS3s have a hard drive. They also have experience with making TVs and are a hardware manufacturer.
Assuming it's successful in it's infancy, they can sell the idea to other companies, and it can be the new standard. Remember when games all came on a cartridge? Sega and Sony broke that, only Sony was successful. It's now the new standard for consoles (See non-portable).
Now the headache thing? Yeah, that can stop a lot of people, here's to hoping though.
Even PCs that are more powerful than the PS3 struggle with 3D. It 'may' be possible but I have severe doubts.
The method that will be used for 3d TV (initially), (and on PC's), is alternating frame stereoscopic 3d.
It's no worse than 3d graphics generally, but you need to render 2 images (one for each eye), so it requires twice the performance you'd need otherwise.
In this case, the 2 images are created by alternating the left and right eye, so essentially it needs double the framerate. (eg. minimum 60fps instead of 30; though most people prefer 60fps or more, so you're looking at 120+ fps for stereoscopic 3d.)
And the reason for the headaches is pretty simple;
We use 3 cues to determine distance:
1. Relative size of similar objects - This is basic perspective, and is why even a 'flat' image, or hand-drawn picture can seem to have depth to it.
2. Stereoscopic effect - This is the one these new 3d systems are adding. (and, for that matter, what the old red/blue anaglyph glasses accomplished.). It's based on the difference in position of the same object as seen from both eyes.
3. Accomodation - This is essentially, a measurement of what 'focal depth' the lens in your eye needs to be at to bring an object at a given distance into focus. - This is still unaccounted for in the current 3d systems we use.
So... Headaches...
Stereoscopic 3d tends to give people headaches because there's a discrepancy between 3, and 2.
The Stereoscopic effect might say an object is 20 meters away...
But the focal distance information you are getting from (3), tells you it is only 5 meters away. (the distance of the screen.)
End result? A splitting headache, as your mind tries (and fails) to work out what the actual distance is, given the contradicting information.
