[Insight-users] Need Help !!! Approximation of a 3D curve with Splines

[Nick Tustison]

Hi Deepak,

Then you have a substantially more difficult problem as a known
parameterization is required for the classes I contributed.  There are
methods to find such a parameterization but I believe that you would have to
implement that yourself.
Good luck,
Nick
