Hello. Does pano2flash support spherical images or is it just cylindrical??

I have tried the program with some spherical and get a little twisted in the buttom and at the top (nadir and zenith).

Anyone who have tried with spherical images??

I think you have this back to front.

A spherical image is one that shows 360 degrees around and 90 degrees up and 90 degrees down = 360 x 180 this a 2:1 aspect where the image is twice as wide as it is tall (exactly).

Where as a cylindrical panorama is 360 degrees around and less than 180 vertical. Typically around 90 to 140 degrees. Say 360 x 110

Does Panorama2Flash support cylindrical images? Yes according to the product page on the Easypano website.

My panos is spherical but when I use them in pano2flash they get distorted in the zenith and nadir :(
Thats my problem ... And then I thought pano2flash only had support for cylindrical.

If I load my spherical images as a cylindrical in "CubicConverter" they get distorted in the same way...

Smooth - have you tried pano2flash with a spherical image?

No I haven't because I don't a license key for it.

I figured you where using a cylindrical image and panorama2flash was projecting it as a distorted spherical.

I suppose I could try the trial. Can you please post a link to your version with the problem?

OK, I just download the trial and ran a 4000x2000 spherical image through it and it displays fine (apart from the watermarks)

I also tested a cylindrical panorama and it also displayed well and as expected.

That image appears not to be spherical.

Please post a link to the .jpg panorama image as you use in the program. If you don't want it public, please send me the link via private message.

Also what camera/lens you are using and what stitching program.

My tester can be seen here

OK, Thank you for the download link to your image.

As expected the image was not a true spherical image. 1995 x 997 Meaning it was not exact 2:1 aspect ratio. I resized your image to 2000x1000 and ran it through panorama2flash software and the result was correct.

Although your panorama image was "close" it was not 2:1 aspect ratio.
