He is correct and slighly wrong at the same time.

360 can technically do exact same 3D as PS3. 1080p image - 720p per eye.

But theoretically PS3 can do 2160p - 1080p per eye due to HDMi 1.3 vs 1.2

However, considering that PS3 and 360 struggle to do a game in 1080p...rendering a game 2160p game is impossible for these consoles...unless that game is pong.

So yes, there is no reason why 360 can't do 3D. Microsoft doesn't sell TVs however, so they really have no reason to push the tech.

Those numbers don't add up. Two 720p images don't equal one 1080p image.

Isn't it more like, one image 720p at 30frames per second and another image 720p at 30 frames per second and the combined image is 720p 30frames per second.

1 plus 1 is 1?

Well, I got confused and put it rong. I dunno why I felt the need to say that the end result is only 30 frames per second to each eye which the other eye can't see and vice versa (because of shutter glasses). But yes, the machine must be able to output 60 frames per second, so 1 plus 1 is 2.

But still, two 720p images dont equal one 1080 image and two 1080p frames definately don't equal one 2160p frame.


Actually 2 720 p images do equal 1080p in real world applications...768p to be exact, which is still considered 720p.  It comes down to amount of pixels rendering the image.

1080p = 1920x1080 = 2073600 pixels

720p = 1360x768 = 1044480 pixels

To do 1080p 3D, a system has to render 1920x1080 lines X 2...and that is 2160 lines. The resolution of 2160p does not exist as far as I know, but I keep it simple so people get the point. Otherwise the resolution that PS3 would have to render (pixel wise) is 2560x1440 to do 1080p 3D

Edit - Also, as far as the earlier statement that a gaming system needs to only render 720p @ 60 hz...hence show 1 720p image@ 30 hz to each eye is not correct. There are many types of 3D (side by side, over under, frame packing, checkerboard)...and for all of them the TV does the image flickering to the viewer, not the PS3/360. The consoles render both images and send it to the TV at the same time, while the TV syncs with the glasses and shows you one image followed by another...
