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. Also, you can control the angle of rotation, and whether translation along the z-axis is performed along with the rotation. The skirt is generated by locating certain topological features. This is true also of lines or polylines.
Vertices generate lines.
This is because the cap is unnecessary. When swept, this will result in two separate surfaces if capping is on, or no surface if capping is off. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataToPolyDataFilter . Returns 0 otherwise.
