Hi<br>
<br>
Is there any filter which set all values smaller a threshold to a specific value (e.g. all values smaller than zero to zero)<br>

<br></div><div><a href="http://www.vtk.org/Wiki/VTK/Examples/PolyData/ThresholdingPoints"></a>to get the IDs of the points that pass your threshold test and then set to the specific value yourself.</div><div><br></div><div>
Maybe someone has a better answer?</div><div><br clear="all">Thanks,<br><br></div><div>David </div></div><br></div>
