[vtkusers] how to get the details about the object created by vtk sources?

[Toron J.]

Thanks, Shriram.

I do know how to read 'cone->GetOutput()->GetPoints()' you suggested. So I tired to add the below codes. 
-------------------------------------------------------------------------
  vtkPoints *points = vtkPoints::New();
    points = cone->GetOutput()->GetPoints(); 

  vtkCellArray *indexes = vtkCellArray::New();
    indexes = cone->GetOutput()->GetPoints(); 
------------------------------------------------------------------------
They did work. Could you correct them or let me know any example like this?

I used the following codes to build a simple cone.
--------------------------------------------------------------------------------------- 
  vtkConeSource *cone = vtkConeSource::New();
      cone->SetHeight( 3.0 );
      cone->SetRadius( 1.0 );
      cone->SetResolution( 6 );
  
  vtkPolyDataMapper *coneMapper = vtkPolyDataMapper::New(); 
      coneMapper->SetInput( cone->GetOutput() );
--------------------------------------------------------------------------------------
Does any one can help me to know how to get the position (x,y,z) of each vertex and the rendering index?      Thanks in advance!
