Though they may look somewhat similar to the untrained eye at relatively
shallow angles, they really are very different. If you try to use a very
wide angle, like several times 360 degrees, then you'll see that the two
projections are completely different in structure from each other. I
doubt that ultra_wide_angle corresponds to anything in the real world. I
would suggest using the fisheye camera instead, with the trick Samuel
suggested.

(By the way, my recent Tunnel Ride animation in p.b.a was made with such
a fisheye camera.)
