Advanced Volumetric Illumination

In order to improve the visual quality and usefulness of direct volume rendering we need to utilize more advanced illumination techniques. The benefits of using more advanced illumination techniques come from improving depth perception as well as making it easier for the user to understand the data which is being visualized. The main challenge exists in creating useful/realistic illumination while still maintaining interactivity. The interactivity can consist of, but is not restricted to, moving camera or light source(s) as well as changing the transfer function.
