Panorama image

Hi all,

I was trying to create a 180 panoramaview from a vehicle interior but couldn't find the right solution yet.

I tried it with spherical map but this has too much distortion, or maybe someone know a way to cut a 180 slice out of this?

And another try was to create multiple images with a Z degree rotation and stitchin it in PTGui. This could do the trick but noise free renders from interiors will take quite some time to render.

Does anyone know a solid and quick solution to create this? I can use PS and PTgui as additional software btw.

Thanks in advance!

Hi Richard,

panorama views like you can do with your smartphone are many photos stitched.

I didn't found a direct setting to achieve it in Vred, unless, like you already said, doing many renders rotated in Z.

But... if you plan to create the 180 panorama to put in on Facebook, you can do it using the 360 spherical image.

if you render in 2:1 aspect ratio and if you put a -ProjectionType="equirectangular" exif info inside the image, Facebook do the right job.

To insert the Exif i used ExifTool. you can find it on the web.

@richard.vinkA9AQ6how are you expecting the final result to look? Do you have an example image of what you are trying to achieve?

You mentioned you think just creating multiple renders with Z degree rotation and stitching but that will just give the same result as a full spherical image in terms of "distortion".

You say you have PTGui so just open the full spherical (equirectangular) image rendered from Vred in PTgui, Click Advanced - Panorama Settings - change the Projection to Equirectangular and you can set the field of view to 180 and vertical to 180. You will then get the 180 section you "want". If it is facing the wrong direction or you want to look up or down etc then just go to the Panorama Editor and just drag around in the viewer.

Best,

Richard

Thanks for your reply.

I couldn't find a good reference image unfortunately. I just wanted a very wide angle image with bot mirrors in it but without too much distortion.

But you're right yeah, the multiple rendering and stitch option would have the same result as a spherical image.

Guess I'll try that then. Thanks for the extra option knowledge in PTgui!

Thanks for the exif tip. Will try that in the future. No plans for facebook images but am trying to get better outputs form PTgui.

Hi,

I would like to try out a rendering for an interior in 360 degree, for example like this:

Konfigurator (mini.de)

Would it be the best to proceed with a 360 degree photo, like Christian Garimberti proposed?

Thanks in advance!

Thomas

Hi @thomas.graeber

If you are using raytracing, just click on your camera and change the projection mode to Spherical Map. Set your Render Image size at a 2:1 ratio (like 8000px by 4000px) and render and you will get a spherical map that you can load in a spherical viewer like the mini example.

Best,

Richard

Hi @thomas.graeber , just an advice. keep the resolution as high as you can, because the viewer show a very small portion of the whole image and if the resolution is low (also 4000x2000 is too low) you will see the pixels...
