Extract Cells By Region should convert voxels to hexahedra
When you run Extract Cells By Region
on a structured type of data (image, rectilinear, curvilinear), it converts the data to an unstructured data. However, it should also convert the cell type to a hexahedron, which has a different point ordering than a voxel. The following replicates the problem.
- Create a
Wavelet
source. Apply. - Add the
Extract Cells By Region
filter. Apply. - Create a new
SpreadSheet
view. - View the result of
Extract Cells By Region
in the spreadsheet view. - Change the
Attribute
toCell Data
. - Note that the
Cell Type
column showsVoxel
type for all cells.
Having Voxel
cells in unstructured data should be avoided because it can lead to problems with some filters that do not handle the order of the points correctly. (See for example #15982 and #21485).
