[ITK-users] Fitting Point Data

[Nicholas Tustison]

Here’s a sample application which uses the BSplineScattered…Filter
to fit a B-splien to a curve

https://github.com/ntustison/Utilities/blob/master/src/FitBSplineCurveToAvantsLandmarks.cxx

where the input points are specified by a text file with the following 
format

0 0 0 0
x1 y1 z1 w1
x2 y2 z2 w2
.
.
.
xN yN zN wN
0 0 0 0

I would like to fit splines instead of using regression because I want to be sure that the curve goes through each point I have given the PointSet.  I have experimented with BSplineScatteredDataPointSetToImageFilter, but I am beginning to think that this class was not designed for this purpose.  Maybe I am wrong.
