possibility of "occulus rift"-tech PS4 exclusivity?

There was some recent VR stuff over on the witness blog.

The images seem to be 1080P at half the horizontal resolution per viewpoint (with the bottom cut off badly in 1 image hence the different resolutions).

If it ran at that resolution, then the console would be rendering the same number of pixels per frame.

 

It wont. 720p is no where near high enough for a HMD similar to the occulus rift. There are doubts that the occulus rifts consumer version with a 1080p screen will be enough.

 

The current Sony glasses use one 720p screen per eye giving full 1280*720 to each eye whereas the Rift uses one 1080 screen divided to both eyes, giving a maximum of 960*1080 per eye and I think it still cuts pixels from that figure.

 

With the current (devkit) Rift, I can clearly see the sub-pixels (red, green and blue stripes) from the image. Anything below 2x1080p isn't going to be commercially viable (IQ is just unacceptable). Rift requires much more pixels than a 60 inch HDTV in order to look good, because the image fills (almost) your whole eye. Rift also requires stable (locked) 60 fps or you will get a headache. 2x1080p@60fps is definitely doable on next gen consoles, but would require sacrifices. As 1080p@30fps is the most popular format right now, a Rift version of a game would need to render pixels at 4x rate (meaning much simpler graphics).

 

A single 2560*1440 (or 2560'1600) screen will just about do to get that 2x1080P definition for a proper Rift-version. 4K would be nice though .

In my previous post I was talking about the supposed commercial version of Rift with the 1080p screen, I know the devkit is a 16:10 1280x800 screen. Have they announced anything about the consumer version yet. Is there still a chance that the first version could be higher than 1080p?

 

If the screen going to cover the whole fov, then it would need at least 8k for me not to notice the pixels. 8k for the whole fov, meaning 8k for each eye.

 

With new phones offering those super resolutions, the screens certainly exist.

 

And there's where your premise dies. Using a VR headset is like pressing your face against the screen.

 

Come on DOA5+ (Vita) port.

 

I thought I read somewhere that the Oculus devs don't think either console is sufficient for the Rift and won't be supported.

 

Will it include rear-touch-panel grope support?

 

However, because of peripherial vision, a lot of the rendered detail is pretty much wasted and never really "seen", or registered, or whatever - I guess you know what I mean.

So this should be a prime candidate for techniques you've talked a lot about, reprojections, interpolated frames, undersampling etc. The only question is if it's good enough to just treat everything on the sides as not important, or does it require eye tracking as well...

 

Headset for the eyes.

You press something else against the vita touch screen.

 

HMZ-T1 has an optical module to make the screen appear further away. What sort of optics module does the Rift use ?

 

IIRC dudes behind O rift said somewhere that even wasnt high enough so noway is 1920x1080 enuf
though I'ld love to see support, it wopuld be my 'killer feature' for either console

 

The major selling point of Oculus Rift is its large FOV (horizontal > 90 degrees). Supposed that the final version has 1000 horizontal pixels (so two eyes combined would be roughly equivalent to 1080p), that's only ~ 11 pixels per degree (perfect human eye acuity is ~ 200 pixels per degree). So it's sort of like looking at a low resolution screen (compared to a normal screen looking distance of 12 inches, that's about 55 DPI, roughly half of normal computer displays).

The bigger problem is, however, the "screen door" effect, as such low resolution will make it possible to see individual sub pixels. It's possible to use a matte filter to "blur" the pixels, but that'd make the visual blurry and probably not a good idea.

Basically it needs about 4K resolution to be roughly equivalent to current normal computer displays, but I guess that probably have to wait.

 

That's very interesting stuff. I would love to see games rendered like that, regardless of the sacrifices.

I think that what sebbbi described happens because the Rift is so close to your eyes that you need maximum resolution.

The Occulus Rift sounds very promising. And now that they have John Carmack working with them, it can be even better.

For now my only gripe about it is that it is a bit bulky and invasive to be 100% comfortable because the people playing it seems to be very isolated from their surroundings.

And playing so very close for hours couldn't potentially develop "lazy eye" in one of your eyes?
