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.)

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter. 

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter.

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter. 

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkSource. 

Construct to compute the gradient of the scalars and vectors. Reimplemented from vtkDataSetSource. 

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.

Control how the filter works to generate tensor cell data. You can choose to pass the input cell tensors, compute the gradient of the input vectors, or compute the strain tensor of the vector gradient tensor. By default (TensorModeToComputeGradient), the filter will take the gradient of the vector data to construct a tensor.
