Hi all, 

I was wondering if any of you have had the same problems as me when using
the Resample With Dataset filter. 

Left and right part of the image are two different grids (different mesh
refinements), with data interpolated from one to the other. In the "spurious
regions" the Resample DataSet Filter sets the vtkValidPointMask to 0. 
I believe this means the interpolation routine is not finding a cell in the
source data containing the points in the input data. Does anyone have a fix
for this ? I'm thinking of changing the tolerance... 

But what is even more strange is that if I interpolate from one grid onto an
IDENTICAL grid, I still get a few points where vtkValidPointMask is 0....

Any suggestions?
