Hey, thanks! With the interpolation of the othogonal views it's getting closer to my wished result. I guess I use the software rendering as I use the "volumerendering" property without any further specifications. I'll take a look into the VolumeDataVtkMapper3D class to get an idea of how to change the interpolation of the volume visualization.
Thanks so far!
