|
|
* @brief Producer for stand-alone data objects.
|
|
*
|
|
* vtkTrivialProducer allows stand-alone data objects to be connected
|
|
* as inputs in a pipeline. All data objects that are connected to a
|
|
* pipeline involving vtkAlgorithm must have a producer. This trivial
|
|
* producer allows data objects that are hand-constructed in a program
|
|
* without another vtk producer to be connected.
