[vtkusers] vtkMaskPolyData

[Yuri Alenka]

Hi,

I have a surface from which I extract a subsample of points. I'm using
vtkMaskPoints for that. Then I do some calculations with the pointset in ITK
and get scalar values for each subsampled point. But I don't know how to set
the values to the original surface because I don't have any indices with the
corresponding original and downsampled points. Is there any way to get
these? If there is an ITK class that can do that it would be also ok but I
have worked more with VTK.
The other problem I am thinking about is: Do I have to specify all scalars
on the surface or are the colors interpolated at points I didn't specify?

thanks
