Wolf3D Engine

The Wolf3D Engine is a raycaster engine developed by John Carmack for the hit FPS game Wolfenstein 3-D. It features smooth scrolling with textured walls, variable screen-size, and sprites. Designed for mid-range 386 computers it was one of the fastest texture-mapped 3D engines to be made available for licensing at the time (1992).

It was officially licensed to JAM Productions to make Blake Stone: Aliens of Gold and Blake Stone: Planet Strike, licensed to Apogee to make ROTT (originally slated to be a Wolf3D sequel), and licensed to Capstone to make Corridor 7 and Operation Bodycount.

It also inspired similar shareware and commercial "doom clones" of the mid-90's.
