Is there an asset that allows creation of 180 degrees panoramic display in Unity?

I'd like to create an effect like this one. It is a panoramic display 180 h-fov and 100 v-fov.
Is there an asset that enables me to achieve such effect?

 

Check out the panoramic framework and capture camera, they may do what you need. There are a few other camera assets such a real lens which could help as well as an asset which does some real scene correcting and looks like it may create this distorted effect. Check the camera assets in the store.Alternatively you could just set the FOV of the camera, below the usual FOV slider there are W and H controls which allow you to set the view format as well.

 

Thanks for the reply. I looked at most of the assets you mentioned, they are pretty much limited. I haven't purchased nor tried them, but looking from the screenshots, none can produce such an effect.

I tried to increase the FOV under Camera component, but increasing camera value makes all the images disappear in the center of the screen.

 

The distortion you're after can't come from a standard view matrix, by my understanding, so you'd have to render to texture then apply a post effect that that - not unlike what the Occulus and similar displays do.

 

@angrypenguin,

I just tried that and you're right. Standard view matrix can't achieve this effect. I looked also into Aubergines post process shader, but not in the list.

Thanks for everyone's help.

 

@ikelaiah - I wasn't certain what effect you were after to be honest. Would you call it a fisheye effect? Possibly have a look at echologin stuff, maybe contact him on the forum thread. He has a really good post process asset which is more of a framework than a set of presets, could be this effect can be easily created using that framework.

 

It's the inverse of a fisheye effect, really. A view matrix projects an image onto a flat surface, which isn't how we really see the world so there's a bit of distortion as you move away from the center. It's not a big deal on small screens, but it's a killer on wrap-arounds. The goal here is to add an inverse distortion to correct the image so that the perspective is correct regardless of where you're looking.

 

@sicga123

echologin, that name rings a bell. I'll look into it speedily. Thank you so much.

 

Could you do a render to texture onto a mesh that has distorted UV's for the effect?

 

Hm, that is one possible solution, but I cant wrap around my head how to mathematically unwrap UV to produce such effect

 

Perhaps check out Paul Bourkes site, he has huge amounts of interesting maths, algorithms, projections, code for all manor of things.

Indeed he has a page dedicated to using the iDome in Unity, that I think includes source demo (not downloaded it) and the page describes in great detail creating the fish-eye effect and then how to wrap it for correct projection onto a spherical mirror.

Even if its not the exact effect you need, it might be a useful starting point along with his other pages ( e.g. stereographics )

 

I always get confused over that stuff. There is a projection correction asset on the store. Unity pro only though. Is this what you mean?:

That's exactly it.
