[Tutor] 3d manipulation

[mdcooper]

Hello all,

I need to make a program that will allow a user to rotate and translate a 
molecule (using the mouse) so as to bring any given atom of that molecule (or 
plane encompassing a number of atoms) to the X-Y plane (i.e. the Z component 
would be 0). I cannot find appropriate modules to allow this. If someone can 
point out a 3d manipulation module, I would be extremely appreciative.

Thanks,

Matthew
