Detailed Description

A general filter for gradient estimation.

Estimates the gradient of a field in a data set. The gradient calculation is dependent on the input dataset type. The created gradient array is of the same type as the array it is calculated from (e.g. point data or cell data) as well as data type (e.g. float, double). The output array has 3*number of components of the input data array. The ordering for the output tuple will be {du/dx, du/dy, du/dz, dv/dx, dv/dy, dv/dz, dw/dx, dw/dy, dw/dz} for an input array {u, v, w}.

Also options to additionally compute the divergence, vorticity and Q criterion of input vector fields.

Return 1 if this class 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 vtkGradientFilter.

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 vtkObjectBase.

This is called within ProcessRequest when a request asks the algorithm to do its work.

This is the method you should override to do whatever the algorithm is designed to do. This happens during the fourth pass in the pipeline execution process.

Reimplemented from vtkDataSetAlgorithm.
