I've never tried it with a vtkStructuredPoints, but it works well for vtkImageData, and I think it should work in your case.</div><div><br></div><div>There are test code samples linked off of the Doxygen page:</div><div><br></div><div><a href="http://www.vtk.org/doc/nightly/html/classvtkThreshold.html">http://www.vtk.org/doc/nightly/html/classvtkThreshold.html</a></div><div><br></div><div>Or, there is at least this one (and maybe more) on the VTK examples Wiki:</div><div><br></div><div><a href="http://www.itk.org/Wiki/VTK/Examples/ThresholdingCells">http://www.itk.org/Wiki/VTK/Examples/ThresholdingCells</a></div><div><br></div><div>(There's also a vtkThresholdPoints filter that outputs vtkPolyData)</div><div><br></div><div>-Eric</div><div><br><div>
