Sounds like a job for vtkThresholdFilter.<br><br>You can use it to simply remove all cells with Velocity < X (or keep all cells with Velocity > X, same thing).<br><br><div><span class="gmail_quote">On 3/7/06, <b class="gmail_sendername">

<br><br>I have an 3D dataset of a turbulent fluid in a channel represented as an<br>unstructured grid. The average velocity at each cell is saved as its<br>cell-data.<br><br>Now I would like to set all cells 100% transparent, which have a lower
