// .NAME vtkHardwareSelectionPolyDataPainter - painter used to render polydata
// for selection passes.
// .SECTION Description

// rendering hardware selection passes.

// Description:
// By default, this painters uses the dataset's point and cell ids during
// rendering. However, one can override those by specifying cell and point
// data arrays to use instead. Currently, only vtkIdType array is supported.
// Set to NULL string (default) to use the point ids instead.

// Description:
// If the painter should override the process id using a data-array,
// set this variable to the name of the array to use. It must be a
// point-array.
vtkSetStringMacro(ProcessIdArrayName);
vtkGetStringMacro(ProcessIdArrayName);
// Description:
// Generally, vtkCompositePainter can render the composite id when iterating
// over composite datasets. However in some cases (as in AMR), the rendered
// structure may not correspond to the input data, in which case we need
// to provide a cell array that can be used to render in the composite id in
// selection passes. Set to NULL (default) to not override the composite id
// color set by vtkCompositePainter if any.
// The array *MUST* be a cell array and of type vtkUnsignedIntArray.
