Derivative Engines
On December 21, 1999, John Carmack of id Software released the Quake engine source code on the Internet under the terms of the GPL, allowing programmers to edit the engine and add new features. Soon programmers were releasing new versions of the engine on the net. A few of the most known engines are:
- GoldSource Engine – First engine to be created by Valve Corporation, and was used on the Half-Life series, gave rise to the Source engine.
- Tenebrae – A derivative that was the first to introduce realtime lighting and shadowing to the Quake engine.
- Telejano – A modification that adds many more features and particle effects.
- Tomaz Quake – One of the first Quake engine modifications on the net.
- Twilight Engine – Fastest of the known Quake engines, this modification is based on performance rather than extra features.

Famous quotes containing the words derivative and/or engines:
“When we say “science” we can either mean any manipulation of the inventive and organizing power of the human intellect: or we can mean such an extremely different thing as the religion of science the vulgarized derivative from this pure activity manipulated by a sort of priestcraft into a great religious and political weapon.”
—Wyndham Lewis (1882–1957)
“America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft that’s 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We’re in that kind of situation. We can have substantial parts of the population committing suicide, and still run and look fairly good.”
—Thomas McGuane (b. 1939)
