Fabien Sanglard reviews DOOM 3's source code

Interested in an open source graphics engine?

The 2004 first-person shooter (FPS) game featured dynamic light and shadow effects Software developer Fabien Sanglard has completed his source code review of the first-person shooter (FPS) DOOM 3. The source code review will be useful to anyone who is considering using or modifying the open source graphics engine of DOOM 3 to either create new games or repurpose it for some other task. Source code for the DOOM 3 was originally released under the GPLv3 by id Software last November, but at 601,047 lines of code, the id Tech 4 game engine it uses is nearly twice as big as its predecessor, which was used for Quake III. Sanglard has previously published similar reviews for classic games such as Another World, Quake II, the classic and iPhone versions of DOOM, and others. Among the topics that Sanglard covers in his recently published DOOM 3 Source Code Review is the graphics engine's renderer. When DOOM 3 was released in August 2004, the engine set new standards with its "Unified Lighting and Shadows" and "Visible Surface Determination", both for runtime and "Multi-pass Rendering" for scene lighting. Sanglard also published a Q&A with id Software co-founder John Carmack in which they discuss further details. Carmack says, for example, that although the team more or less "slid into" its decision to use the C++ programming language for DOOM 3 instead of C, he is now certain that C++ is the right choice, especially for large multi-developer projects that place high priority on performance.

Carmack: Doom 3 Source Code 'Packaged And Tested'

id Software's John Carmack has revealed that the source code for 2004 horror shooter Doom 3 is ready to be released, and is now waiting for final clearance. The id co-founder and lead programmer had originally confirmed at QuakeCon earlier this year that the source code for the game would be made available sometime after the release of open-world shooter Rage. Carmack has now confirmed that the code is about to be released, stating via Twitter, "Doom 3 source is packaged and tested, we are waiting on final lawyer clearance for release." During the announcement at QuakeCon, the industry veteran also challenged other developers to release their source code for study as well, saying it helps the developer community. id is well-known for releasing source code for its past games. Last year the company made the source code for Wolfenstein: Enemy Territory and Return To Castle Wolfenstein publicly available. Just weeks ago, following an update for both Doom Classic and Wolfenstein 3D Classic on the App Store, the company also made available the source code for both updates.
