To the game code, the world is still just a tile map, but for rendering, each map was exported as a general-purpose 3D model, and the artists could then go through it and spend the polygons any way they liked, without the limits of line-of-constant-z software rasterization that we lived with on the mobile phones.
From John Carmack
It is a shame that homebrew development can't be officially sanctioned and supported, because it would be a wonderful platform for a modern generation of programmers to be able to get a real feel for low level design work, to be contrasted with the high level web and application work that so many entry level people start with.
