Dear all,
I am working on a custom filter that works with PointData only. Hence I am using a CellDataToPointData operation if the input is CellData.
If I were to keep CellData across the entire custom fitler, I would have to double the amount of code to account for CellData operations through the entire custom filter.
However, I have discovered the existence of 0D Cell Data vertices thanks to the VTK_VERTEX and VTK_POLY_VERTEX VTKCell types (1 and 2 respectively)
What is the philosophical difference between 0D CellData and PointData ?
For example, does the choice between the two affects the way gradients are computed (via a gradient filter) or the way data are integrated (via vtkIntegrateAttributes) ?
Would it be wiser to write a custom filter only with CellData functions and perform a PointData to 0D CellData VTK_POLY_VERTEX operation if the input is PointData, rather than a PointData custom filter ?
Thanks a lot,
Sincerely yours
