mitk::SurfaceVtkWriter writes mitk::Surfaces as vtkPolyData in any supported VTK file format (via template mechanism). For writing the data, the Geometry / transform contained in mitk::Surface is applied to the individual points, since VTK file formats do not support storing of transforms.
In some cases, it is not desirable that the poly data are transformed automatically, e.g. when the Geometry/transform is stored separately.
CAUSE OF THE BUG
Feature request.
PROPOSED SOLUTION
The writer class should be extended with an option to enable/disable the application of the transform.
