Hi Rob,

Try vtkThreshold.

Objet : [vtkusers] Converting Rectilinear To Unstructured 

Dear vtkusers,

Does anybody know an easy way to convert a vtkRectilinearGrid to a
vtkUnstructuredGrid on a basis of scalar cell data? For instance remove the
mesh cells with a scalar smaller than a certain value, and save the
remaining mesh cells as an vtkUnstructuredGrid.
Will it also be possible to eliminate the grid points that are unused ?

Or do I alternatively have to write a new vtk class to perform this action? 

All suggestions will be appreciated. 

Kind regards,
