[vtkusers] Curve / Equal Subdivision

[Jean-Hugues Royer]

Hi,

I also tried vtkSplineFIlter using SetSubdivideToLength() and 
SetLength(distance).

But the result is that the points are not equally distributed.

When you provide a curve the beginning and ending points are not equally 
distributed while the center points are.

When you provide a straight line no points at all are equally distributed.

I get exact same result when using 
vtkSplineFIlter/SetSubdivideToLength/SetLength and 
vtkParametricSpline/SetParametricFunction/SetUResolution.

May be I'm missing something ?
