Data picking with volumes works by using the PickVoxel method in the
IDLgrVolume object. It will basically tell you the non-transparent voxel
that is closest to the viewer.

You can also mix in isosurfaces with the volume rendering to make the
layered objects. See the ZBUFFER property on IDLgrVolume.

So, yes, you should be able to do something like the kitware picture.
