### Code

Glyph2D.py

    #!/usr/bin/env python

    import vtk

    def main():
        points = vtk.vtkPoints()
        points.InsertNextPoint(0,0,0)
        points.InsertNextPoint(1,1,0)
        points.InsertNextPoint(2,2,0)

        polydata = vtk.vtkPolyData()
        polydata.SetPoints(points)

        # Create anything you want here, we will use a polygon for the demo.
        polygonSource = vtk.vtkRegularPolygonSource() #default is 6 sides

        glyph2D = vtk.vtkGlyph2D()
        glyph2D.SetSourceConnection(polygonSource.GetOutputPort())
        glyph2D.SetInputData(polydata)
        glyph2D.Update()

        mapper = vtk.vtkPolyDataMapper()
        mapper.SetInputConnection(glyph2D.GetOutputPort())
        mapper.Update()

        actor = vtk.vtkActor()
        actor.SetMapper(mapper)

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

        renderer.AddActor(actor)

        style =  vtk.vtkInteractorStyleImage()
        renderWindowInteractor.SetInteractorStyle( style )

        renderWindow.Render()
        renderWindowInteractor.Start()
