[vtkusers] give direction to cylinder

[Gonzalo Amadio]

Thank you for the response..

I am reading this : http://www.vtk.org/doc/release/5.6/html/a02007.html that
I think is what I need. Because I don't have all the mapper and actor part
and as it is said there, if I am not understanding wrong, vtkTransfrom work
on the actor and rendering part, and vtkTransformPolyDataFilter directly on
the rotation of the figure itself :

" The difference between the two methods is that vtkActor's transformation
> simply effects where objects are rendered (via the graphics pipeline),
> whereasvtkTransformPolyDataFilter<http://www.vtk.org/doc/release/5.6/html/a02007.html> actually
> modifies point coordinates in the visualization pipeline"


A piece of my code to make it clear :

mitk::DataNode::Pointer resNode = mynode;
>


 // Create a cylinder
> vtkSmartPointer<vtkCylinderSource> cylinderSource =
> vtkSmartPointer<vtkCylinderSource>::New();
> cylinderSource->SetCenter(cen[0], cen[1], cen[2]);
> cylinderSource->SetRadius(5.0);
> cylinderSource->SetHeight(200.0);
> cylinderSource->SetResolution(100);
>

> //Rotation of the cylinder here , I need a polydata as an output

// i.e the cylinder rotated



mitk::Surface::Pointer surface = mitk::Surface::New();
> surface->SetVtkPolyData(cylinder);
> resNode->SetData(surface);
>


mitk::DataStorage::Pointer dsp = myDataStorage;
> dsp->Add(resNode);


Am I right?


Thank you!
