### Description

This example creates a pentagon.

### Code

RegularPolygonSource.py

    #!/usr/bin/env python

    import vtk

    # Create a pentagon
    polygonSource = vtk.vtkRegularPolygonSource()

    # polygonSource.GeneratePolygonOff()
    polygonSource.SetNumberOfSides(5)
    polygonSource.SetRadius(5)
    polygonSource.SetCenter(0, 0, 0)
    polygonSource.Update()

    mapper = vtk.vtkPolyDataMapper()
    mapper.SetInputConnection(polygonSource.GetOutputPort())
    actor = vtk.vtkActor()
    actor.SetMapper(mapper)

    renderer = vtk.vtkRenderer()
    renderWindow = vtk.vtkRenderWindow()
    renderWindow.AddRenderer(renderer)
    renderWindowInteractor = vtk.vtkRenderWindowInteractor()
    renderWindowInteractor.SetRenderWindow(renderWindow)

    renderer.AddActor(actor)
    renderer.SetBackground(.3, .3, .5)  # Background color purple

    renderWindow.Render()
    renderWindowInteractor.Start()
