* @class vtkRegularPolygonSource
* @brief create a regular, n-sided polygon and/or polyline
*
* vtkRegularPolygonSource is a source object that creates a single n-sided polygon and/or
* polyline. The polygon is centered at a specified point, orthogonal to
* a specified normal, and with a circumscribing radius set by the user. The user can
* also specify the number of sides of the polygon ranging from [3,N].
*
* This object can be used for seeding streamlines or defining regions for clipping/cutting.
