Store vtkAlgorithm input/output information.
void SetInputData(vtkDataObject *)
Assign a data object as input.
Generic filter that has one input.
virtual void SetInput1Data(vtkDataObject *in)
Set the two inputs to this filter.

virtual void ThreadedRequestData(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector, vtkImageData ***inData, vtkImageData **outData, int extent[6], int threadId)
If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method.
