<DIV>Hello,</DIV>
<DIV>Actually I do my black cells filtering with a threshold. But it is very slow since I have a lots of cells (350000), and I will have more laters...</DIV>
<DIV>I'm looking for a faster solution, that would allow me to blank more than 1 value, in real time. I played with blanking with vtkStructuredGrid, but, again, I failed to use it.I don't need a new DataSet that vtkThreshold creates.</DIV>

Point Data or Cell Data are used (it can be a lookuptable), and you can choose to keep only points or cell upper than a threshold, lower than a threshold or between two thresholds.<BR>Perrine<BR>_______________________________________________<BR>This is the private VTK discussion list. <BR>Please keep messages on-topic.
