/**
* @class vtkExporter
* @brief abstract class to write a scene to a file
*
* vtkExporter is an abstract class that exports a scene to a file. It
* is very similar to vtkWriter except that a writer only writes out
* the geometric and topological data for an object, where an exporter
* can write out material properties, lighting, camera parameters etc.
* The concrete subclasses of this class may not write out all of this
* information. For example vtkOBJExporter writes out Wavefront obj files
* which do not include support for camera parameters.
*
* vtkExporter provides the convenience methods StartWrite() and EndWrite().
* These methods are executed before and after execution of the Write()
* method. You can also specify arguments to these methods.
* This class defines SetInput and GetInput methods which take or return
* a vtkRenderWindow.
* @warning
* Every subclass of vtkExporter must implement a WriteData() method.
*
* @sa
* vtkOBJExporter vtkRenderWindow vtkWriter
