[vtkusers] How to show and control one vtkSphereWidget in dif ferent windows?

[Nigel Nunn]

Hi Chunyan, 
 
vtkSphereWidget is great for manipulating objects, but it 
depends upon getting attached to an "Interactor".  If you 
just want to show a sphere in multiple renderWindows, then 
vtkSphereSource may be better.  From the documentation: 
 
 "vtkSphereSource creates a sphere (represented by polygons) 
  of specified radius centered at the origin. The resolution 
  (polygonal discretization) in both the latitude (phi) and 
  longitude (theta) directions can be specified. It also is 
  possible to create partial spheres by specifying maximum 
  phi and theta angles. By default, the surface tessellation 
  of the sphere uses triangles; however 
  you can set LatLongTessellation to produce a tessellation 
  using quadrilaterals."  
 
Do you have access to the documentation?
