</div>The cells seem to be well formed, but there are tons of NAN points<br>
that I guess the cells are referencing. At line 250ish in<br>
vtkClipPolyData.cxx:<br>
<br>
// evaluate implicit cutting function<br>
for ( i=0; i < numberOfPoints; i++ )<br>
{<br>
s = clipScalars->GetComponent(cellIds->GetId(i),0);<br>
cellScalars->InsertTuple(i, &s);<br>
}<br>
<br>
's' is getting set to -inf for many of the cells, which is my best<br>
quick guess at what is causing the NANs. Kind of looks like a bug to<br>
me, unless I'm setting up something incorrectly in the example.<br>
