[vtkusers] R: Thresholding to distance from a mesh

Hi Ambar,

maybe you should take a look at vtkImplicitModeller, if I've understood what you are trying to do that could be the right class.

Hello,

I'm trying to use the vtkThreshold class to filter some data, where I
want the scalar for the threshold to be determined by how far the
current point is from a base mesh A. However, I don't understand how
to use the scalar value extracted from each point by vtkThreshold, and
nor do I understand how that is calculated. Also, the rule I want to
use in thresholding involves specifying a certain physical distance
from the base mesh; how do I find out what scale/distance to use?

Please feel free to ask any following questions.

Best,
Ambar
