Hello Sascha and List,

thanks for the patch. I try it and worked fine. As you pointed out,
the 2D views run extremely low.

btw, in general, MITK has trouble with 2D rendering of meshes:

- when more than 2-3 meshes are rendered, turns low
- also when zooming

do you guys experience the same? is vtkPolyDataCutter really slow in
generating contours?

one good source of test data is
http://www.ircad.fr/softwares/3Dircadb/3Dircadb2/index.php
there are CT datasets and segmentations, both as labeled images and
vtkPolyDatas.

Loading 2-3 of such organ meshes make the application run really slow.

best regards,
sebastian
