<div class="moz-cite-prefix">Hi Bill and Jean-Hugues,<br>
<br>
I was able to reproduce the bug for a straight line with vtk-5.10
python (script attached). I also get the same spline from paraview
by exposing the vtkSplineFilter (hopefully!).<br>

Can you provide a small, compilable example that illustrates the
problem?<br>

<br>
I also tried vtkSplineFIlter using SetSubdivideToLength()
and SetLength(distance).<br>
<br>
But the result is that the points are not equally
distributed.<br>
<br>
When you provide a curve the beginning and ending points are
not equally distributed while the center points are.<br>
<br>
When you provide a straight line no points at all are
equally distributed.<br>
<br>
I get exact same result when using
vtkSplineFIlter/SetSubdivideToLength/SetLength and
vtkParametricSpline/SetParametricFunction/SetUResolution.<br>
<br>
May be I'm missing something ?

<br>
I have a curve which is a vtkPoints array.<br>
<br>
I would like to generate another vtkPoints array
where every consecutive points have the same
distance. (basically divide the curve to n equals
segments)<br>
<br>
I tried to use
vtkParametricSpline/vtkParametricFunctionSource
but I was only able to change the number of points
to another value but I didn't find how to specify
that these new points should be equally
distributed.<br>
<br>
Any idea ?<br>
