Tutorial: Stereoscopic panorama with Corona + Cardboard

[TomG]

Glad you got it all working in Photos 360! And glad you signed up for Corona VR too, excellent!

For the Samsung app, it displays the photo as flat by default (so you see both left and right eye image one above the other), and you can tap on the GearVR control pad to bring up a menu which includes the display option, tap on that until you get to 3DV, then when the menu fades out it will pop into that mode and work as expected. That said, the Samsung VR app is less crisp and sharp than Photos 360 or Corona VR, so I wouldn't actually recommend using it - but the option is there if needed for some reason.

Hi Guys!

Is anybody knows what HMD is now giving the best quality when viewing the VR / 360 images?
I mean the quality, which is most close to Gear VR...
Actually, the problem is about iPhone. Because there is no VR Glasses made by Apple for iPhone..

I tested few google cardboards with my iPhones and at this point VR Box 2.0 looks the best. But the bigger phone - the better image.

Thanks!

Just curious, I was looking at Pano2VR a loooong time ago, before VR took off so quickly in 2016. Has anyone looked into this software to be used for VR? Thanks! Looking into it again, because of the ability to create hotspots in your Pano's that would allow for you to move throughout your space.

[TomG]

For hotspots to move through your space, I'd suggest Corona VR :)

Well, now that I know Corona is this far along, I think I'm going to try it out. Thanks, Tom G. for the heads up! I signed up, so now I will wait to see if they allow me in. :)

Best,
Mike

Welcome aboard! Good to hear you signed up :)

Thanks Tom! I'm really looking forward to it!

Hi,
unfortunately, my 5.5" smartphone is "only" FullHD.
I created this simple scene for a client (testing purpose). In attachment the Left and Right render (8K)
With 8k or 4k, the difference is really minimal.
I want to ask you, for the users with 4K resolution phone, if the can play with the 8k render (6K and 4k) if they see the difference.
And, is it evident the 3D effect in this render?

Thanks!

Textured version

Looks really nice in CoronaVR! I pasted the two images into one over/under stacked format and loaded it in. I really like the volumetrics in 3D from the sun, that looks awesome! And I love the sense of height and space.

I did find it slightly disconcerting to see I was hovering in space above a very long drop - I wanted to get back onto the safety of the platform behind me :)

[TomG]

BTW on the questions in your previous post - my testing done on a Galaxy S7 with the GearVR. Looks great there as mentioned! The 3D effect is very distinct and strong. For comparing 4K and 8K, I didn't see two different versions, but happy to take a look if those are available, usually the higher resolution does make a difference to image sharpness in the VR app, with 4K being a recommended minimum.

I just loaded it into my cardboard with a 720p display, and it's still pretty awesome! The feeling of depth and height is super clear in this one. I also discovered a nice feature in my pano viewer - if you pinch the screen you can change fov, so you can end up with a "tiny planet" style 3d fisheye panorama. That's crazy, but it's still stereoscopic!

Here is a merged version, hope Cecofuli doesn't mind:

[cecofuli]

I'm surprise for your excitement =)
I created this scene  just for fun!

TomG: if you look at back, the untextured version, is in 8K.
Maru: everithing is ok

[TomG]

I did have a look at the 8K, not quite comparing apples-to-apples since one is textured and one is not, but I would say the 8K was sharper. That said, there wasn't anything in the 4K that looked bad in any way.

I like these images just because we don't see too many VR images yet, plus I like the scale of the place, great to see such a huge space done in VR. Then the sunlight was also really good, I take it that was volumetrics? Never thought on trying those in VR, will have to give it a go sometime just for the fun of it! It looked awesome in this scene, however it was created :)

[cecofuli]

So, is for you enough 4K? Because 8K = 4x rendering time for the same quality.
If 4K is good enough, these isn't sense to render in 8K. =)
This is my doubt
