inconsistent output from contour filter for multiblock data sets with image data and unstructured grids
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When contouring a multiblock data set where some of the blocks are vtkImageData and some of the blocks are vtkUnstructuredGrids, the output is inconsistent in that the output from the vtkUnstructuredGrid passes all of the fields while the output from the vtkImageData doesn't pass the contoured variable but does pass a Normals array.
To reproduce:
- create a wavelet source
- create a clip filter to create an unstructured grid
- use the group data set filter to group them into a multiblock data set
- create an elevation filter
- create a contour filter and contour by Elevation
- look at the output and note that both Normals and Elevation point data arrays are listed as partial
