Err, as far as I knew Carmack INVTENTED the virtual memory system that Doom used. Without which, Doom would have had to use Wolf 3D style graphics.
|
Doom allocates a single block of memory from the operating system and then manages that memory itself using what they call "zone memory allocation". Nothing particularly tricky about it. Basically a doubly linked list of memory blocks. It isn't virtual and it isn't the reason for the graphical improvements over Wolf 3D.
The zone allocation can still be found in the Quake 3 source code, however it isn't the primary memory manager as it is in Doom.

Learn something new every day. I must admit, when I was playing Doom and Doom 2, I was a bit young to understand such things. I've read some articles, but the main thing is I just remember dad rambling about some stuff and how great it was when he was setting Doom up for us. 
Still, if he authorised Doom the movie, Carmack has something wrong in the head. Even if that something wrong isn't open source and his programing.
