/**
 * @class   vtkCursor3D
 * @brief   generate a 3D cursor representation
 *
 * vtkCursor3D is an object that generates a 3D representation of a cursor.
 * The cursor consists of a wireframe bounding box, three intersecting
 * axes lines that meet at the cursor focus, and "shadows" or projections
 * of the axes against the sides of the bounding box. Each of these
 * components can be turned on/off.
 *
 * This filter generates two output datasets. The first (Output) is just the
 * geometric representation of the cursor. The second (Focus) is a single
 * point at the focal point.
