|
|
* @brief Pass input input data through to the output
|
|
*
|
|
* vtkPassThrough simply passes input data to the output. By default, the input
|
|
* is shallow-copied (using `vtkDataObject::ShallowCopy`). If `DeepCopyInput` is true,
|
|
* then the input is deep-copied (using `vtkDataObject::DeepCopy`).
|
|
*
|
|
* The output type is always the same as the input object type.
