    Re: Celestial globe gores
    From: Matus Tejiscak

    I've done something similar in the past. I used Transverse Mercator with 12 gores and it all turned out to fit reasonably well.

    My use case was a bit different, though: I had to make a globe of a city (Brno, Czech Republic). I used the stereographic projection to project the city onto a sphere, and then Transverse Mercator to make the gores. Since we used an existing globe, we could just measure one gore and apply its shape as an alpha mask to the transverse-mercator stripes in post.

    I used a Perl script to automate Panotools, so it's similar to K McGrath's solution with Hugin because Hugin uses Panotools under the hood as well.

    I was only in charge of the remapping and producing the 12 stripes, which I e-mailed to a friend, who carried out the actual physical construction. I attach a couple of images he sent to me, for illustration.
