[Paraview] [EXTERNAL] Warp by scalar for CELL_DATA

[Magician]

Hi Mohammad,


According to my research, Cell Data to Point Data is just calculating
averages of surrounding cells.

I think it's not proper to explain the function as 'interpolation'.
Also I hope it will be adapted to geometric interpolation method.
