Hi! I’d like to move a slice through the 3D data volume and animate its track. I was wondering how I can define the path/track on which the slice moves? I tried using view-\>animation view of the slice I have but did not follow how I can define the path. Is “slice offset values” what I’m looking for? if yes, how can I define the trajectory? Thank!

Defining a complex trajectory will be hard, offset value is just offsetting the plane in the plane axis.

What you can do with the slice filter is animating the X/Y/Z of the plane but it will be hard to position correctly.

You can also create an actually animated data starting with the plane source then use RessampleWithDataSet, this should be simpler.
