Well, a rectangular projection can only display images with <180
degrees field of view (and 120 degrees for practical use), so for this
projection, the FOV field needs to be modified.
How about: Internally, the FOV is still set at say 300 degrees,
however if you switch to rectangular, the FOV switches to 170
degrees. This value is displayed, but internally hugin holds on to
that 300 degrees. When you continue switching, the fov is taken
from the "hidden" value, and not from the displayed one.
People expect the switching of projections to be nondestructive. So
they want to be able to try all of them (and see their restrictions)
without having to fiddle with anything else.
How about:
1st time switch to a projection: assume nothing but the input images and
the control points, store resulting FoV for this projection
2nd time you switch to a projections: use stored value for this
projection, unless something changed in input images or control points.
(then goto 1st, perhaps after asking the user, if he/she changed any
values manually)
I don't think the FoV calculation should take that long, so it shouldn't
impact performance too much.
