[Insight-users] ITK support for path generation

[Nicholas Tustison]

Hi Prashanth,

Your email motivated me to complete an additional portion of my B- 
spline code which would answer the second component of your problem,  
i.e. determining whether or not a given point lies on the curve (with  
some tolerance).  What the code actually does is, in the B-spline  
curve case, determine the parametric values of a point on the curve  
closest to a user-specified point.  Are you still interested in this  
second part?

Nick
