Does VR just enhance the 3D effect?

324 viewsBiologyOther

For example, I can look at a 3D animation on my phone, and my brain will somehow interrpet that the depth in the animation, even though im watching it on 2d screen.

Then, the way to make it more 3d, is to view it through vr, because binocular vision gives the effect of depth?

ie. vr headset has 2 screens for left and right eye, and it enhances the 3D effect?

Your brain uses all sorts of different cues to measure depth. Two of the most powerful are focus and parallax – neither of these exist in a normal single image. Now, you can do without them, especially if you’re used to looking at pictures and screens you may not even notice they’re missing, but they are. It feels very different for most people when they’re actually there.

In a binocular image you can have parallax. Still no focus, though.

that is one, albeit one of the smaller parts. VR also allows you to move the screen with your head movements and to look around, making viewing something much more immersive

I wouldn’t say it “just enhances the 3D effect”

Because at the end of the day VR is 100% true 3D images.

The way you perceive the real world as 3D in the first place is by getting a slightly different image for each eye as you move throughout space, and a few other more subtle clues that you alluded to with 2D images (stuff like, shadows, different sizes of identical objects base on distance, etc).

Assuming the VR headset is high quality enough and running correctly then as far as your brain is concerned that IS 3D. If it’s just a “3D effect” then *reality itself* is also just a 3D effect, it’s just one that been on for your entire life.

With this wording, it doesn’t “enhance” it, it creates it. When you looked at the 2d image, you/your brain *invented* the 3d data with the info given, letting you *believe* that it’s 3D.

In VR, it 100% *is* 3D, in full contrast the 100% not-3D initial image.

The sub-millimeter precision in head tracking also let’s you experience it in ways that just looking at other 3d methods cannot give you. It feels a bit like you have a window into another world, because it’s precise enough to fool a good part of your senses.
