Wolfenstein 3D

Wolfenstein 3D is the video game which started the first person shooter genre on the PC; it was created by ID Software and published by Apogee in 1992. In the game, the player is a soldier attempting to escape from a Nazi building; there are many guards with pistols and machine guns about, as well as attack dogs. The building has a number of hidden passages containing various treasures, food supplies, and medical kits, as well as various guns and ammunition.

An expension pack, Spear Of Destiny, was also released.

The game was originally released on the PC and then ported to Macintosh computers, Apple IIGS, Super NES, and Atari Jaguar. The source code of the game was published by ID Software in 1996.

To render the walls in pseudo-3D, the game used [ray casting]?, a special case of ray tracing that sent out one ray for each column of pixels, checked if it intersected a wall, and drew textures? on the screen accordingly, creating a depth buffer against which to clip the scaled sprites that represented enemies, powerups, and props.

A new first-person shooter, [Return To Castle Wolfenstein]?, a loose sequel (though with the advance of technology the graphics and gameplay will likely be vastly different), is currently in production.
