#Documentation # @brief Change the type of display to 3D # # As in Step2, load one or more data sets (many image, surface # and other formats), but display it in a 3D view. # The QmitkRenderWindow is now used for displaying a 3D view, by # setting the used mapper-slot to Standard3D. # Since volume-rendering is a (rather) slow procedure, the default # is that images are not displayed in the 3D view

//## we want volume-rendering, thus we switch it on by setting
//## the Boolean-property "volumerendering" to "true".
