Why would the planes rotate if they are not children of the globe?

Hi all,
I am at the tail end of a project done in Five3D after doing a few
different ones in Papervision and I am stuck on a fundamental feature
that I hope someone who payed attention in math class (which I didn't)
could help me out on. I am doing something that has movement similar
to WP-Cumulus, i.e. items placed around a virtual globe, with each
item always facing front when that globe is rotated. I know
papervision had something pre-built for this type of thing, but Five3D
doesn't, so I suspect I may have to get tricky with some maths to keep
all panes facing front.
Anyone know where to start on this?, currently, if I spin the
globe on it's Y axis, and turn each item on that globe but the inverse
of its rotation, and works fine around that axis alone. Throw in both
x and y rotation at the same time though and things go a little skewy.
Any help would be most appreciated and will earn me a couple of
hours extra sleep :)
Cheers
Adam
