Image Distortion

[IceBlueFire]

I've tried a variety of panorama apps for the iPhone, but when i load them into the viewer, i get some image distortion that stretches the images in a weird way, however the images look fine while looking at them in the native apps. Is there a setting that i'm messing up somewhere that is messing with this?

Are you referring to the the horizontal and vertical lines not being straight ? This is normal has how the sphere is drawn for performances.

Or the top and bottom being stretched ? It also occurs on desktop and this is because your panorama is not a sphere !

If you want to use partial projections (like rectilinear) you must define the corresponding area using XMP tags, see my answer here #78 (comment)

Yeah, i'm referring to the cars looking super compact when you look straight on at them, but then stretching back out as you continue to spin around. I'll take a look at that answer and give it a go, thanks!

One question regarding those numbers...How did you come up with them, specifically for the "full_width" and "full_height", as well as the "cropped" numbers?

The best way is to fit your image in a 2:1 image (this is the format of an equirectangular projection).

If your source is 3000x500 (a standard horizontal panorama)

      {
          full_width: 3000
          full_height: 3000/2 = 1500
          cropped_width: 3000,
          cropped_height: 500,
          cropped_x: 0,
          cropped_y: (1500-500)/2 = 500
      }
