vtkContour3DLinearGrid does not pass cell data
Problem statement
When one has a valid vtkUnstructuredGrid
with both point and cell data, applying the vtkContour3DLinearGrid
filter to the data set does not propagate/pass the cell data attributes to the contoured geometry.
Small investigation
It would seem that this is related to the implementation of vtkContour3DLinearGrid
which just completely ignores cell data.
Steps to reproduce
- Generate an unstructured grid with point and cell data (a
vtkWavelet
followed by an append and then a random attributes filter for example) - Apply the contour filter
Here is a ParaView state file to reproduce: ContourUnstructuredCellDataIssue.pvsm
