To create an instance of class vtkExtractVectorComponents, simply invoke its constructor as follows
obj = vtkExtractVectorComponents
obj
is an instance of the vtkExtractVectorComponents class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkExtractVectorComponents = obj.NewInstance ()
vtkExtractVectorComponents = obj.SafeDownCast (vtkObject o)
obj.SetInput (vtkDataSet input)
- Specify the input data or filter.
vtkDataSet = obj.GetVxComponent ()
- Get the output dataset representing velocity x-component. If output is
NULL then input hasn't been set, which is necessary for abstract
objects. (Note: this method returns the same information as the
GetOutput() method with an index of 0.)
vtkDataSet = obj.GetVyComponent ()
- Get the output dataset representing velocity y-component. If output is
NULL then input hasn't been set, which is necessary for abstract
objects. (Note: this method returns the same information as the
GetOutput() method with an index of 1.)
Note that if ExtractToFieldData is true, this output will be empty.
vtkDataSet = obj.GetVzComponent ()
- Get the output dataset representing velocity z-component. If output is
NULL then input hasn't been set, which is necessary for abstract
objects. (Note: this method returns the same information as the
GetOutput() method with an index of 2.)
Note that if ExtractToFieldData is true, this output will be empty.
obj.SetExtractToFieldData (int )
- Determines whether the vector components will be put
in separate outputs or in the first output's field data
int = obj.GetExtractToFieldData ()
- Determines whether the vector components will be put
in separate outputs or in the first output's field data
obj.ExtractToFieldDataOn ()
- Determines whether the vector components will be put
in separate outputs or in the first output's field data
obj.ExtractToFieldDataOff ()
- Determines whether the vector components will be put
in separate outputs or in the first output's field data
