HONOR AMONG THIEVES (released in 2004 for the PlayStation 2) included an innovative anaglyph 3D feature. With the red/cyan glasses included with the game, players could experience real-time stereographic visuals in most gameplay areas. Producing stereographic anaglyph images (AKA anaglyphs) is a fairly mature practice among photographers.
Even so, special problems arise when generating anaglyphs for consumer televisions, in real-time, and within a "free" camera system. This talk presents the pro forma methods for producing anaglyphs, as well as several tricks for producing effective stereographic effects within a video game.
