Is there any simple to compute do product between cell normal and a vector like vtkVectorDot

Hello,vtkVectorDot can be used to compute the dot product between POINT normal and vectors,any similar way for CELL normals?

Interesting, that filter could easily be modified to operate on cell data as well. Do you want to try submitting a MR?

Also, you could use one of the VTK programmable filters to do the same thing. And possibly even the vtkArrayCalculator, although I am not sure about this since I don’t use the filter that often.

Thanks,I will try to find an example about vtkArrayCalculator,and submit MR
