[vtkusers] Point rendering : how to filter values with a vtkLookupTable

[REGAT-BARREL Aurélien]

Hello,
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...
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.

Did you try vtkThreshold or vtkThresholdPoint whick allow to create a new unstructured grid or a new polydata? 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.
