Wolfenstein 3D (1992)
The Grandfather of the 3D First-Person Shooter and Raycasting Breakthrough
Wolfenstein 3D is a pioneering 1992 first-person shooter developed by id Software and published by Apogee Software. Released on May 5, 1992, it popularized the fast-paced action framework and HUD conventions of the FPS genre via John Carmack's revolutionary real-time raycasting graphics routine on IBM PC-compatibles.
Mathematical Raycasting and Smooth PC 3D
Programmer John Carmack implemented an ultra-fast raycasting algorithm that cast a single ray per screen column, determining wall slice scales in hardware without floating-point math. This yielded an unprecedented illusion of smooth 3D motion on commodity Intel 286 and 386 personal computers.
Shareware Commercial Triumphs
Partnering with Apogee Software's Scott Miller, id Software distributed Episode One for free across BBS networks and mail-order floppy disks, requiring players to purchase Episodes Two through Six directly. The massive royalty cashflow established id Software as a powerhouse and funded the creation of Doom.
