Hi Dora, well, this is strange. Is it possible that you give me/us somehow access to a 4D image you created so that we can check?

I managed to create 4D data using the methods you mentioned and I can navigate through the time steps. It all works fine but I've faced this new problem when I add the 4D object as a node to the datamanager. The crosshair disappears from the 4 standard windows/renderers. I can still click on different locations of the image and it seems to respond to the mouse clicks. More importantly for me is that the 3D window does not render the image either it is just blank! It renders my 4D mesh (without the usual three planes) but not the 4D image. I tried to force update/render all the windows but nothing seemed to make any difference. Any ideas? Many thanks again.

For example, many methods of mitk::Image or mitk::Surface have an optional parameter t (time step), which is 0 by default for 3D data. 3D+t data is also supported by our Workbench application as you can slide through the time steps in the Image Navigator (usually in the bottom left). Our standard image file format NRRD also supports reading and writing 3D+t images. 3D+t DICOM images work as well. I'm not sure regarding the VTK file formats for surfaces but you have to be at least careful for file formats like STL, as they don't support 4D surfaces. For example, when you save a 4D surface as STL file, MITK creates a STL file for each time step, but currently they cannot be read in again as 3D+t surface. If you are interested in making 3D+t data out of a series of 3D data, have a look at methods like mitk::Image::SetVolume() or mitk::Surface::SetVtkPolyData(), which have the t parameter as mentioned above. With the Movie Maker plugin you can even create animations of 3D+t data, for example, see the beating heart example at the very bottom in the Movie Maker documentation: http://docs.mitk.org/2015.05/org_mitk_gui_qt_moviemaker.html Best, Stefan ________________________________________ Von: Admin Uniapp [contactuni...@gmail.com<mailto:contactuni...@gmail.com>] Gesendet: Dienstag, 16.

My understanding was to somehow load images and meshes one by one, putting the thread to sleep for a second or so and then display the next item. Can I load all of the files at once and then dynamically access the (standard) editor to display them one by one? Is there a more elegant solution? Like building some sort of a 4D image or a 4D mesh from data I have and then display it using one of the features of MITK ...
