vtkAxesActor axes 

vtkAnnotatedCubeActor cube
  [cube GetCubeProperty] SetRepresentationToWireframe
  [cube GetCubeProperty] SetAmbient 1
  [cube GetCubeProperty] SetDiffuse 0
  cube TextEdgesOff

vtkPropAssembly assembly
  assembly AddPart axes
  assembly AddPart cube

vtkRenderer ren
    ren AddActor coneActor
vtkRenderWindow renWin
    renWin SetSize 600 600
    renWin AddRenderer ren
vtkRenderWindowInteractor iren
    iren SetRenderWindow renWin

vtkOrientationMarkerWidget widget
