#Documentation # @brief Use several views to explore data # # As in Step2 and Step3, load one or more data sets (many image, # surface and other formats), but create 3 views on the data. # The QmitkRenderWindow is used for displaying a 3D view as in Step3, # but without volume-rendering. # Furthermore, we create two 2D views for slicing through the data. # We use the class QmitkSliceWidget, which

//## The two slices are also shown at their correct position in 3D as
//## well as intersection-line, each in the other 2D view.
