I've spent so many hours reading Quake source code, trying to figure out how it all works. Such a marvelous game.

For those who find this topic interesting, there is a walkthrough of the Quake source code by Fabien Sanglare here.

He has also written a number of Game Engine Black Books on other games such as Doom.

For the graphics side of things there is a PDF by Michael Abrash that also covers Quake.

You may be confusing the various engines. The first link is about the Quake 3 engine, the second one is about Quake 1.

Quite right, thanks for pointing it out.

The Quake rasteriser inner loop with its overlapped fdiv is still one of my all time favourite pieces of code.
