*
|
|
* vtkExtractTimeSteps extracts the specified time steps from the input dataset.
|
|
* The timesteps to be extracted are specified by their indices. If no
|
|
* time step is specified, all of the input time steps are extracted.
|
|
* This filter is useful when one wants to work with only a sub-set of the input
|
|
* time steps.
