[vtkusers] Problem with camera position

[Michele Nigri]

Hi everyone,

when I set up my camera in a VTK app, in the rendering window I don't
see my axis actor until I interact with it, like zooming or
rotating...
This is my code:

	// add renderer in the render window
	renderWindow->SetSize(this->windowWidth, this->windowHeight);
	renderWindow->AddRenderer(renderer);

	// custom interactor
	MyInteractorStyle *style = MyInteractorStyle::New();
	interactor->SetRenderWindow(renderWindow);
	interactor->SetInteractorStyle(style);
	
	renderer->SetBackground(bgColor.r, bgColor.g, bgColor.b);

	// create camera
	vtkCamera *camera = vtkCamera::New();
	camera->SetPosition(8120, 10718, 7066);
	camera->SetViewUp(0, 0, 1);
	renderer->SetActiveCamera(camera);
	
	//pick event handling
	PickEventCallback *pickObserver = PickEventCallback::New();
	vtkPropPicker *picker = vtkPropPicker::New();
	picker->AddObserver(vtkCommand::EndPickEvent, pickObserver);
	interactor->SetPicker(picker);

	// render an image (lights and cameras are created automatically)
	// and begin mouse interaction	
	interactor->Initialize();
	interactor->Start();	

	//Finalize the rendering window
	renderWindow->Finalize();

Please help!!!
