I have some code to load ADCIRC data into memory as vtkPolyData. It's been working great until yesterday when I tried to pass it to a vtkThreshold to eliminate some of the "masked" values, and it segfaulted. a backtrace showed it somewhere in a vtkDataArray::GetValue call.
<br><br>I fought with it for a good while, before I just (on a whim) switched from vtkPolyData to vtkUnstructuredGrid, with all VTK_TRIANGLE cells. And low and behold, it works.<br><br>Is there some reason why a vtkPolyData can't be thresholded (
VTK5.0 stable)?<br><br>----------------------------------------<br>Randall Hand<br>Visualization Scientist<br>ERDC MSRC-ITL<br>
