### Description

import vtk

# create a rendering window and renderer

ren = vtk.vtkRenderer() renWin = vtk.vtkRenderWindow() renWin.AddRenderer(ren) WIDTH=640 HEIGHT=480 renWin.SetSize(WIDTH,HEIGHT)

# create a renderwindowinteractor

iren = vtk.vtkRenderWindowInteractor() iren.SetRenderWindow(renWin)

# create cone

cone = vtk.vtkConeSource() cone.SetResolution(60) cone.SetCenter(-2,0,0)

# mapper

coneMapper = vtk.vtkPolyDataMapper() coneMapper.SetInput(cone.GetOutput())

# actor

coneActor = vtk.vtkActor() coneActor.SetMapper(coneMapper)

# assign actor to the renderer

ren.AddActor(coneActor)

# enable user interface interactor

iren.Initialize() renWin.Render() iren.Start()
