Visible, Volumetric, and Inverse Volumetric

Visibility is what allows you to see the actual beams or shafts of light. Volumetric is more accurate then visibility in that it also reacts to objects casting shadows through its beam when objects are in the path of the illumination. This accuracy is a trade off for rendering speed. Inverse volumetric inverts the effect so only the light passing the object shows a beam.
