compute derivatives of scalars and vectors
vtkCellDerivatives is a filter that computes derivatives of scalars and vectors at the center of cells. You can choose to generate different output including the scalar gradient (a vector), computed tensor vorticity (a vector), gradient of input vectors (a tensor), and strain matrix of the input vectors (a tensor); or you may choose to pass data through to the output.
Note that it is assumed that on input scalars and vector point data is available, which are then used to generate cell vectors and tensors. (The interpolation functions of the cells are used to compute the derivatives which is why point data is required.)

virtual |
Control how the filter works to generate vector cell data. You can choose to pass the input cell vectors, compute the gradient of the input scalars, or extract the vorticity of the computed vector gradient tensor. By default (VectorModeToComputeGradient), the filter will take the gradient of the input scalar data.
