what do you call 'codewise'?... this system is visually based on
true perspective. Doesn't have to be 3-d 'codewise'. I wrote a fractal
program that renders several layers of squares and i would call this
3-d. the original math stuff is based on 3-d true perspective. Wolf's
too, even though the code might have been simplified to be faster...
when you look back at where they took their code, you can see it all
comes back to 3d math.
If you're talking about the map, well, the map != the whole thing.
Like, there are things other than the map.
In Wolfenstein, the map function is (x,y) -> b, where b is the block
type.
 SI> DOOM is kinda 3d.  Its map has x and z co-ordinates, and each sector has 
In Doom, the map function is more or less (x,y) -> (b,z) though it's a
bit more complicated than that... certainly more 3-d in it, but since
wolf is 3-d, doom, being more 3-d, is 3-d too.
 SI> Now Quake and Descent are in 3-dimensions all the way!
possibly true, though i don't know the details. it is at least more
than doom.
