That's essentially eight shots (regardless of sweep-of-image) and is usually
never enough.  You likely need twice as many, at the minimum.
In addition, I would ensure that for each individual image in the 360 degree
stitch sequence, the camera points directly away from the center of the
building - the correct orientation from the building center.
Finally, the radial distance covered increases as you move towards the
center of a building side (sides are flat, so you accelerate).  The math is
pretty simple but I was unable to load the image from Bruce's site.

Usually can never work...

Nice problem...

Happy to discuss this in person, I will be at MacWorld Expo in the Adaptec
booth all next week.

Hope to see you there
