[vtkusers] Probing a surface

[Kevin Wright]

Hi All,

I have a polydata surface that is an unstructured mesh (mostly triangles, 
fairly irregular).  I would like to create a more normalized set of points 
by sampling the surface at regular intervals.  I have tried using 
vtkProbeFilter, which works sporadically (I assume because of roundoff?), 
but not nearly well enough to implement.  So my question, in several parts 
is: Am I right that the vtkProbeFilter will not work reliably without 3D 
elements?  Is there another way to do this with existing VTK 
classes?  Would the best solution be a new filter specifically made to 
probe surfaces?

Thanks,
Kevin.
