Removing Panaromic Distortion
Hello everyone,
I have a panaromic video (please refer the image link) – which will be projected onto a 360 (four walls) – (plz refer the youtube link)
How can I remove the (spherical) distortion from the 3d renders.
Can anyone please help.Image

If the four walls you’re projecting onto are close to equal size, you can change the projection from equilateral (as in your original) to cubic projection (6 faces of a cube) in Skybox, omit the top and bottom (“floor” and “ceiling”), then split the four “walls” of the cube into four separate projections.

Thanks for the reply. The problem is, they are not equidistant… The basic shape of this room is like a cuboid. It’s like , 2 walls of 4000px and other 2 walls are 2600px.
The total length of all walls put together would come around 13500px. And the height is 1500px. -
My next approach would be to split the panorama into those 4 comps and use optics compensation to remove the distortion. You will need a different amount of the effect on the two differently-sized comps to make the image edges match. I doubt that they will match perfectly, since optics compensation works on both axis, but you have corners in the room anyways.
If you want something that appears more accurate — i.e. (un)distorts only in one axis direction — I believe you’ll have to use a custom distortion mesh.

You can use this on the individual walls (on an adjustment layer matching the size of the comp, for instance) and get something quite close to that transform.
