The radius won't make a difference with spherical mapping, just as long as
the camera is in the center of the sphere. Use a sky_sphere, which is sort
of a sphere with infinite radius.

To see how the mapping works, make a small image in MS Paint or something
that's, say, 8x8, and put a checkerboard pattern on it. Then map it
spherically onto a sphere, and look at the sphere from the outside of it.
That should give you a good idea what's going on.
