Example of Carmack's stencil shadowing in Doom 3. Shadow volume is a technique used in 3D computer graphics to add shadows to a rendered scene. It was first proposed by Frank Crow in 1977 [1] as the geometry describing the 3D shape of the region occluded from a light source. A shadow volume divides the virtual world in two: areas that are in ...

Carmack used these capabilities to create a buffer that is 64 pixels wider and taller than the screen, leaving room for two extra rows and columns of tiles in the buffer off the edge of the screen. He used the offset capabilities of the card to let the screen slide through the buffer for smooth scrolling, which partially reveals the extra tiles.
He co-founded id Software and designed their early games, including Wolfenstein 3D (1992), Doom (1993), Doom II (1994), Hexen (1995) and Quake (1996). His designs and development tools, along with programming techniques developed by the id programmer John Carmack , popularized the first-person shooter (FPS) genre.
