Hi Sandra, starting with revision 27263, MITK has gained much better support for visualizing unstructured grids. If you are using the "ExtApp", you might want to use the new "org.mitk.gui.qt.ugvisualization" bundle (you have to switch it on via CMake).
See bug http://bugs.mitk.org/show_bug.cgi?id=5597 and http://bugs.mitk.org/show_bug.cgi?id=5876 for more information. Your code below looks good and if you don't have special requirements, you don't need to look at UnstructuredGridVtkMapper3D and VtkPropRenderer. When you call node->SetData(grid) in step 2, the UnstructuredGridVtkMapper3D mapper is automatically used as the default mapper for your node. The mapper makes use of a couple of properties attached to your node which you can modify by code to render the grid in special ways. For a supported list of properties, have a look at mitk::UnstructuredGridVtkMapper3D::SetDefaultProperties(...). If something is buggy, please provide feedback in the bugs above.
