+#
+# This example creates a polygonal model of a cone, and then renders it to
+# the screen. It will rotate the cone 360 degrees and then exit. The basic
+# setup of source -> mapper -> actor -> renderer -> renderwindow is
+# typical of most VTK programs.
+#
+
+#
+# First we include the VTK Python packages that will make available
+# all of the VTK commands to Python.
+#
+import vtk
+import time
+
+#
+# Next we create an instance of vtkConeSource and set some of its
+# properties. The instance of vtkConeSource "cone" is part of a visualization
+# pipeline (it is a source process object); it produces data (output type is
+# vtkPolyData) which other filters may process.
+#
+cone = vtk.vtkConeSource()
+cone.SetHeight( 3.0 )
+cone.SetRadius( 1.0 )
+cone.SetResolution( 10 )
+
+#
+# In this example we terminate the pipeline with a mapper process object.
+# (Intermediate filters such as vtkShrinkPolyData could be inserted in
+# between the source and the mapper.)  We create an instance of
+# vtkPolyDataMapper to map the polygonal data into graphics primitives. We
+# connect the output of the cone souece to the input of this mapper.
+#
+coneMapper = vtk.vtkPolyDataMapper()
+coneMapper.SetInputConnection( cone.GetOutputPort() )
+
+#
+# Create an actor to represent the cone. The actor orchestrates rendering of
+# the mapper's graphics primitives. An actor also refers to properties via a
+# vtkProperty instance, and includes an internal transformation matrix. We
+# set this actor's mapper to be coneMapper which we created above.
+#
+coneActor = vtk.vtkActor()
+coneActor.SetMapper( coneMapper )
+
+#
+# Create the Renderer and assign actors to it. A renderer is like a
+# viewport. It is part or all of a window on the screen and it is
+# responsible for drawing the actors it has.  We also set the background
+# color here
+#
+ren1= vtk.vtkRenderer()
+ren1.AddActor( coneActor )
+ren1.SetBackground( 0.1, 0.2, 0.4 )
+
+#
+# Finally we create the render window which will show up on the screen
+# We put our renderer into the render window using AddRenderer. We also
+# set the size to be 300 pixels by 300
+#
+renWin = vtk.vtkRenderWindow()
+renWin.AddRenderer( ren1 )
+renWin.SetSize( 300, 300 )
+
+#
+# now we loop over 360 degreeees and render the cone each time
+#
+for i in range(0,360):
+    time.sleep(0.03)
+
+    renWin.Render()
+    ren1.GetActiveCamera().Azimuth( 1 )
