6.4.1 Trends and Analysis

Rendering engines are so powerful nowadays that getting the initial shadow prop-

erties set up should be very fast with the usual 3D modeling techniques (i.e., chang-

ing lights and objects can result in real-time feedback of the shadowing result). e

cheats suggested by Barzel [36] should be able to get the precision of the shadow

properties achieved quickly as well.

e inverse techniques described above might not prove as useful today, except

in some very special cases. Work by Mitra and Pauly [414] and shadow art forms, as
