[Insight-users] calculating bsplines and direction vectors

[Mira Pommer]

Hi Nicholas,

first of all, thanks for your input! If your b-spline implementation is 
able to compute a one-dimensional line through three-dimensional points, 
and not only a two-dimensional surface like in the paper cited below, it 
would be very helpful, if you could send me a preliminary version of 
your implementation.

Kind regards, Mira
