* @class vtkAbstractMapper3D
* @brief abstract class specifies interface to map 3D data
*
* vtkAbstractMapper3D is an abstract class to specify interface between 3D
* data and graphics primitives or software rendering techniques. Subclasses
* of vtkAbstractMapper3D can be used for rendering geometry or rendering
* volumetric data.
*
* This class also defines an API to support hardware clipping planes (at most
* six planes can be defined). It also provides geometric data about the input
* data it maps, such as the bounding box and center.
