Converting 2 large files to a single large KRO for conversion to cube

Hi, I have a gigapixel image which is 300,000 x 60,000 pixels. It's cylindrical with the horizon offset. HFOV = 180, VFOV=45 (the photo is of only land, there is no sky)

I need to convert a cylindrical image which exists as 2 master files (each is 300,000px wide PSB) to Cubic.

My question: Do I need to combine the source files into a single KRO first, and then convert to cube? Or can I do it all in one go?


thanks!

Jeffrey,

Just use the "Convert SPHERE CUBE Droplet" tool of krpano.

I created for you a test case: I changed the original spherical pano (360x180 100.000x50.000px https://pavel.ursiny.sk/pano/cz/Praha/Petrin_2015/ ) to a cylindrical 360x83 10.000x2.816px in PTGui.
Then I dropped the image on the "Convert SPHERE CUBE Droplet" and made out of cube the multiresolution vtour:

I haven't limited the view of the testcase's vtour to not see the zenith and nadir parts of the panorama.

Enjoy!
Pavel
