cylindrical spline conversion to cartesian spline!

[Yogesh Sajanikar]

Hi,

My sincere apologies if I have posted a too novice question.

I am working on a problem where I need to transfer a b-spline defined in
cylindrical coordinates into a ( / may be an approximate ) cartesian
b-spline. I would like to know of any methods / algorithms to solve the
problem.

Thanks in advance.

Regards,
Yogesh
