[vtkusers] important, please help simple question

[Armeni Davide]

Hi to everyone,
i've a simple question ..

I've an actor an i want to use a vtkOutlineFilter
that contains the actor that i have to render 
calculating the bounds ...

there is a function that automatically do this ?
This is the code:

int Visualize(CString pathoffile)
{
	vtkPolyDataReader *part = vtkPolyDataReader::New();
	part->SetFileName(pathoffile);

	vtkOutlineFilter *outline = vtkOutlineFilter::New();
	outline->SetInput((vtkDataSet*)part->GetOutput());

	vtkDataSetMapper *partMapper = vtkDataSetMapper::New();
	partMapper->SetInput((vtkDataSet*)part->GetOutput());
		
	vtkPolyDataMapper *outlineMapper = vtkPolyDataMapper::New();
	outlineMapper->SetInput(outline->GetOutput());

	vtkPolyDataMapper *partMapper1 = vtkPolyDataMapper::New();
	partMapper1->SetInput(axes->GetOutput());
	
  //The actor is a grouping mechanism: besides the geometry (mapper), it
  // also has a property, transformation matrix, and/or texture map.
  // Here we set its color and rotate it -22.5 degrees.
  vtkLODActor *partActor = vtkLODActor::New();
  partActor->SetMapper(partMapper);
  partActor->GetProperty()->SetColor(0.9, 0.82, 0.54);
  partActor->RotateX(30.0);
  partActor->RotateY(-45.0);

  vtkActor *outlineActor = vtkActor::New();
  outlineActor->SetMapper(outlineMapper);
  outlineActor->GetProperty()->SetColor(0.9, 0.82, 0.54);
  	  
  // Create the graphics structure. The renderer renders into the 
  // render window. The render window interactor captures mouse events
  // and will perform appropriate camera or actor manipulation
  // depending on the nature of the events.
  
  vtkRenderer *ren1 = vtkRenderer::New();
  vtkRenderWindow *renWin = vtkRenderWindow::New();
  renWin->AddRenderer(ren1);
  
  vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
  iren->SetRenderWindow(renWin);
  
  ren1->AddActor(outlineActor);
  
  ren1->SetViewport(0.0, 0.0, 1.0, 1.0);

  ren1->AddActor(partActor);

  ren1->SetBackground(1.0, 1.0, 1.4);
  	
  renWin->SetSize(800, 800);
  
  // We'll zoom in a little by accessing the camera and invoking a "Zoom"
  // method on it.
  renWin->Render();
  
 
  // This starts the event loop and as a side effect causes an initial render.
  iren->Start();

  // Exiting from here, we have to delete all the instances that
  // have been created.
  part->Delete();
  partMapper->Delete();
  partActor->Delete();
  ren1->Delete();
  renWin->Delete();
  iren->Delete();

  return 0;
}
