// .NAME vtkCompositePolyDataMapper2 - mapper for composite dataset consisting
// of polygonal data.
// .SECTION Description
// vtkCompositePolyDataMapper2 is similar to vtkCompositePolyDataMapper except
// that instead of creating individual mapper for each block in the composite
// dataset, it iterates over the blocks internally.

#ifndef vtkCompositePolyDataMapper2_h
#define vtkCompositePolyDataMapper2_h

#include "vtkRenderingOpenGLModule.h" // For export macro
#include "vtkPainterPolyDataMapper.h"
#include "vtkSmartPointer.h" // for vtkSmartPointer

class vtkCompositeDataDisplayAttributes;

{
public:
  static vtkCompositePolyDataMapper2* New();
  vtkTypeMacro(vtkCompositePolyDataMapper2, vtkPainterPolyDataMapper);
  void PrintSelf(ostream& os, vtkIndent indent);

  // Description:
  // Returns if the mapper does not expect to have translucent geometry. This
  // may happen when using ScalarMode is set to not map scalars i.e. render the
  // scalar array directly as colors and the scalar array has opacity i.e. alpha
  // component. Note that even if this method returns true, an actor may treat
  // the geometry as translucent since a constant translucency is set on the
  // property, for example.
  // Overridden to use the actual data and ScalarMode to determine if we have
  // opaque geometry.
  virtual bool GetIsOpaque();

  // Description:
  // Set/get the composite data set attributes.
  void SetCompositeDataDisplayAttributes(vtkCompositeDataDisplayAttributes *attributes);
