Hi Dora, MITK supports 4D images as well as 4D surfaces (meshes), also commonly named 3D+t images/meshes, as most of the time such data is technically handled as a series of 3D data over time. 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] 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 ...
