id Software had developed pseudo 3D engines for several games before Quake. Each engine had
progressively more advanced
pseudo 3D technology. Two notable examples are the Wolfenstein 3D engine and the Doom engine, which are often
claimed to
be id Tech 0 and 1, respectively.

Originally known as the "Quake engine", it was originally written to power 1996's Quake. It featured true 3D
real-time
graphics via software rendering and is the first id Software engine to use the client–server model and a virtual
machine
for game code written in QuakeC. 3D model animations lack interpolation, appearing choppy and uneven. The source
code
was released on 21 December 1999 under GPL-2.0-or-later.
