An interesting read into some of the insights that Carmack had which lead to the revolution that was Quake can be found in the "Ramblings in Realtime" articles[1] by Michael Abrash[2], who helped John develop Quake's 3D engine. Abrash wrote the rather famous "Graphics Programming Black Book", now available for free[3].
