 * @class   vtkAxes
 * @brief   create an x-y-z axes
 *
 * vtkAxes creates three lines that form an x-y-z axes. The origin of the
 * axes is user specified (0,0,0 is default), and the size is specified with
 * a scale factor. Three scalar values are generated for the three lines and
 * can be used (via color map) to indicate a particular coordinate axis.
