[vtkusers] VTKProbeFilter

[Louis-Jacques Lalonde]

Hi !
 
I'm using vtkProbefilter with a polydata of points as a source and a
line as the input.  Like someone said here
 
http://public.kitware.com/pipermail/vtkusers/2000-October/004532.html
 
the output of the vtkProbefilter is zero or black in RGB if you use a
points-only data set.  Someone knows an easy way to solve this ?  I have
large polydata, around 500-600k points  and I have 200-300 points on my
line that I want to interpolate.  I need to do some kind if
interpolation for the points I choose on my line.
 I don't want to choose an interpolation method that takes too long.  It
is possible for example to get N scalairs value in my polydata  around
the point where I am (in the line) and do a mean of these value ?  How
can I do that without searching in all my polydata ?
 
If anyone modified the vtkprobefilter code do solve this problem, I
would be very happy to contact him/her.
 
Thanks !
