Ready Player One: Don't Miss This Immersive VR Experience

[jtlz]

One movie you shouldn't miss this week!

Because it may come to us in the not so distant future...

In the movie.. a character at one point couldn't differentiate between the virtual world and real world.. may I know what resolution must the VR google be to make it almost indistinguishable from reality?

I have tried the Samsung S8 Gear VR and it is low resolution like CGA monitor back in the 1980s.
If you haven't tried any VR googles yet. What's amazing is the 3Dness effect due to the inclusion of fish eye like lens making you sense depth.. so a VR google is not just like looking at tiny monitor inside the googles but it is immersive.. you need to try it to appreciate it!

I read the book, can't wait to see the movie.

I think we're already at the resolution required to make a virtual world indistinguishable. It's fidelity that's lacking, not resolution. GPUs simply don't have the algorithms or processing power required to render anything close to photo-realism (dynamic lighting is the main bottleneck.) I'd take a guess that AAA studios will begin to punch through the uncanny valley by 2025.

What are you talking about.. even with the high resolution of our existing googles now at https://newatlas.com/gear-vr-vs-oculus-rift-specs-comparison-2017/49015/

We can still see pixels inside the googles (because we are so close to the screen and it has fish lens of some kind).. so the resolution we may need not to see pixels may be 14400x12800 or so (how do you compute the resolution where you can't see any pixels anymore).. anyone?

Did the math, you were right. We’re not there yet, but getting close. Resolution doesn’t matter, it’s density.

Humans can destignguish individual pixels greater than about one arcminute. So the formula for density would be

60 * distance from eyes * tan(1 deg). So at one inch from your eyeball you’d want a resolution of about 3500ppi.

Shouldn't you factor in the fish eye lens?

The fish eye lens is what causes the immersive experience in VR.. before I looked through one.. I thought it was just like looking at tiny monitors inside googles. but it was not.. it has to be tried to believe...

Depends on your vision. Some people can distinguish things that others cannot.

There is also a color quality. Blends of three monochromatic pixels make the color in most screens. Real objects are usually sunlight with some frequencies adsorbed/transmitted and frequencies scattered. We are used to thinking of objects as the same thing whether they are under florescent, incandescent, or in direct sunlight. Walk around after a snowstorm and really focus on the color of the snow. The snow under HPS streetlights is not the same as the snow under mercury vapor lights. Most peoples brains accept the difference and render it irrelevant. The conscious mind usually registers "this parking lot has snow" and not "this lot is scattering HPS light". The contrast between leaves sprouting in the spring and leaves in summer is strong in most trees. If you held the leaves next to each other you could clearly see it. You can compare leaf color to the evergreen needles nearby. Most people believe that maple leaves are one color until fall when they turn to red or orange. We also do not think of the trees and other objects changing color when the sun sets but it is happening. A lump of coal and a snowball both scatter sunlight and are essentially the same. Our brains decide which is coal and which is snow because of the relative intensity. The VR goggles can be good enough if the goggles cover both eyes even if you could easily tell which eye was seeing reality using VR monocles.

Another angle, why would you want to simulate reality? Creating fantasy worlds sounds like a much better option to me.

There is also the issue that the standard RGB color system that we use in most digital media is simply not capable of rendering the entire human visual range: https://en.wikipedia.org/wiki/RGB_c...ciples_for_the_choice_of_red,_green,_and_blue
