 * @class   vtkQuadRotationalExtrusionFilter
 * @brief   sweep polygonal data creating "skirt" from free edges and lines, and lines from vertices
 *
 * vtkQuadRotationalExtrusionFilter is a modeling filter. It takes polygonal
 * data as input and generates polygonal data on output. The input dataset
 * is swept around the z-axis to create new polygonal primitives. These
 * primitives form a "skirt" or swept surface. For example, sweeping a
 * line results in a cylindrical shell, and sweeping a circle creates a
 * torus.
 *
 * There are a number of control parameters for this filter. You can
 * control whether the sweep of a 2D object (i.e., polygon or triangle
 * strip) is capped with the generating geometry via the "Capping" instance
 * variable. Also, you can control the angle of rotation, and whether
 * translation along the z-axis is performed along with the rotation.
 * (Translation is useful for creating "springs".) You also can adjust
 * the radius of the generating geometry using the "DeltaRotation" instance
 * variable.
 *
 * The skirt is generated by locating certain topological features. Free
 * edges (edges of polygons or triangle strips only used by one polygon or
 * triangle strips) generate surfaces. This is true also of lines or
 * polylines. Vertices generate lines.
 *
 * This filter can be used to model axisymmetric objects like cylinders,
 * bottles, and wine glasses; or translational/rotational symmetric objects
 * like springs or corkscrews.
 *
 * @warning
 * If the object sweeps 360 degrees, radius does not vary, and the object
 * does not translate, capping is not performed. This is because the cap
 * is unnecessary.
 *
 * @warning
 * Some polygonal objects have no free edges (e.g., sphere). When swept,
 * this will result in two separate surfaces if capping is on, or no surface
 * if capping is off.
