A shortcoming of this approach is the engine's inability to render soft shadows and global illumination.Īs well as dynamic lighting and shadows, the Doom 3 engine was id Software's first to make extensive use of bump mapping. This allows lights to cast shadows even on non-static objects such as monsters or machinery, which was impossible with static lightmaps. By contrast in the new Doom 3 engine, most light sources are computed on the fly. All 3D engines up to and including Quake III and Unreal Tournament had computed or rendered lightmaps during map creation, saving that information in the map data, which made the lighting extremely static. The key advance of the Doom 3 graphics engine is the unified lighting and shadowing. GUI surfaces that add extra interactivity to the game.Complex animations and scripting that show off real-time, fully dynamic per-pixel lighting and stencil shadowing.The source code for Doom 3 was released under the GPL.Īccording to John Carmack, the lead graphics engine developer of id Software, the "tripod of features" in Doom 3 technology is: It received a positive reception for its fear-inspiring atmosphere and groundbreaking graphics, but was criticized mainly for its otherwise simplistic gameplay and clichéd horror effects.
