Technical information and development

• Examination of Doom 3 Technology - by Zaldron

An excellent article on the technologies likely to be used in the new Doom, based on the video that was shown at the MacWorld 2001 Expo. A must read for anyone interested in the technical details. Note : this article was written in March 2001, so it's horribly outdated and in need of an update. It should still give you a good idea of some aspects of the Doom III engine though.
