Extra wide images

[Krisztian Gulyas]

How could I render an extra wide image (like a panoramic image). It needs to be very wide (the aspect ratio is 3:1 and FOV 100 degrees), but if I use a wide angle lenses, It doesnt look good enough. Can I use somehow 2 cameras and merge the two images in PS later? OR can I do it with a single camera? I tried many things, but I just could not get it right. the distortion is the real problem.

Im using Max 2014 and VRay 2.4

Thanks

Aspect ratio is just a matter of setting the resolution. Instead of 1280:720, you can go 2160:720. that would give you 3:1 aspect ratio.

 

2 Cameras would give you 2 lens warp with 2 centers. that would be odd.

I already set the resolution. Actually I forgot to mention (and now corrected above) that the FOV is over 100 degrees and I want to get rid of the distortion.

Move your camera further away and lower the fov?

Move your camera further away and lower the fov?

There are two options. Do what Nicolai said or else you can consider a cylindrical panorama which will eliminate stretch distortion but things will get curvy. No point in messing around with multiple images etc. just to end up with the same result. For cylindical pano you can use camera override to change the FOV (use warped spherical old style). You won't see it in the viewport though, only at render time.

Maybe camera clip view can solve your problem?

Move camera back, and then turn cliping views in camera propertise, so play with 2 red zones, to match your view.

Also, post the scene screen, if you wish.

Want some like this one?

Get the image the way you want it without distortion with a telephoto lens then do "render region" and select your skinny area.

Thank you all for replying.

 

I cant move the camera back because it's an L shaped room, but I changed a few things (removed/added some things) and now the FOV is 96 degrees, the distortion is still noticable on the armchair, but it's much better now.

Tried the warped spherical camera, but the lines are curved too much.

Here is the image after changing the FOV (WIP)

and here is the room after the images were removed.

 

By the way, what do you think about the room?

i had this problem once, my camera got stuck in the back of the room and i had to hire a 3d modeller to move the walls so i could take my photo

[Krisztian Gulyas]

I use a FOV of 90+ degrees often so I wanted to learn how to get rid of the distortion, because sometimes moving the camera back is not a solution.

i have a nice 14mm prime lenses for my vray cameras (VR mount) that captures small spaces well

however some distortion is to be expected....
