How can I rotate a volshow image programatically?

Hi!

I have a volshow image of a brain and I want to rotate it programatically (and then use getframe to write a video with writeVideo).

I tried using CameraPosition and CameraDirection of the Viewer3D parent object, but I have no clue how these work (and whether I need to move LightPosition with the camera). It seems highly complicated to move the camera around the brain like this. Is there an easier way to do that? Can I rotate the volume instead of the camera?

Did you want to just rotate the data and axes together, like with view, or did you (for some reason) want to rotate the volume within the fixed axes (keep axes and viewing angle fixed)?

Like with "view" would be fine but that does not seem to work for volshow, only for normal figures. Matt J's answer below (Transformation property) seems to work.

Yes, you can use the Transformation property.

They don't work. You don't have camera properties in a volume rendering such as what you have in a 3D plot.

Thanks, that works. Rotation with rigidtform3d wobbles a bit back and forth, but I think I'll manage with that. I probably need to move the origin (rotation center) of the volume, which I have not found, yet.
