[vtkusers] vtkthreshold on unstructured grid + data sets

[ycollette.nospam at free.fr]

Hello,

I found the solution:
I added a Update just after setting up the vtkthreshold filter. And now, I've got all my arrays back in the unstructurec grid.

Objet: [vtkusers] vtkthreshold on unstructured grid + data sets

Hello,

I've got an unstructured grid data set with some data Arrays ('DISPLACE', 'STRES-CA', etc ...).
I use vtkThreshold to extract a part of the unstructured grid (the vtkThreshold is based on 'CellMaterials' array).

Just before using vtkThreshold, I've got an unstructured grid with the arrays, but after vtkThreshold, I get only an unstructuredgrid.

My question is: how can  I use vtkThreshold to perform the thresholding on the whole data set (unstructuredgrid + arrays) ?

Best regards,

YC
