Oh boy, you're going to make me relive this I think. I wrote the node
builder for WADED before BSP and IDBSP came out... there were very few
documents about it at the time too. It took about a straight week of
constant programming to get it, and it's gone through several changes and
bug fixes since. It was hell. I don't know if you've seen it now, but it
works perfectly (and fast) in WADED v1.42 and above (blockmap builder had
a bug until v1.45 btw, not the node builder).
Read over the specs in DMSPEC16.TXT (which btw weren't out when I wrote
mine) first, and from there I'll gladely help you... There are a few
others out there that completely understand it also.
To answer your question: you do fork nodes at a nodeline (sometimes a
2-sided line, but not always), and it does fork into 2. I don't know
where you heard 4. Each of those two nodes is then evaulated. If one
needs to be split further, it does fork into another 2. If not, then it
becomes a SSECTOR (end of the branch techincally). There are multiple
checks you have to do to determine if a node needs to be split further
into two. There can't be any 2-sided lines within it. There can't be any
two walls with an inward angle of greater than 180 degrees. And, oh boy,
I forget the third case. Look over the specs. This routine requires
some AI too, to determine the best BSP tree. I've seen some editors and
builders that build poor trees that could potentially slow Doom down.

I have the 3D library that DoomCAD uses: it should work fine as a nice
wireframe engine. It accepts "patches" as input: I guess those would be
the concept of a LineDef extended into the third dimension.

I'm actually not even as far as "wireframe" yet... all I've got for
sure are the vertices. But I'm working on it.

I wonder if there's a chance ID will put some of the nice aspects of the
Heretic engine into an update for Doom2. Things like the new sector types
and sector orientated sounds, and if any new line defs. Plus the obvious
new abilities of looking up and down. I wouldn't take the inventory
abilities over. The line defs and sector aspects should be simple enough,
I'd think anyways. This still doesn't explain the 7mb file POLAR zip.
Just the sector specified sounds would give a new dimesion to doom. I hate
having to sacrafice the monster sounds to add to the atomsphere. See I
don't like music in my wads, ruins the mood IMHO. I'd rather have little
sound bites creating the mood for the player.
Ahh well, so as far as line defs go, are there any new, and all that
exciting new defs in Heretic?

I suppose it would be great for DOOM wads, but I get the feeling that iD
is working full bore on Quake. And I'd personally prefer it that way.

No, but they're missing some of the newer 1.4+ linedefs (like blazing).
Apparently they're still using the 1.2 linedef set. I think they made
their own W1 Secret level. That's about it.

Personally I think adding the sectors with directional "wind" could have
some really groovy uses in Doom. Think of the ****ed up kind of crossfire
you could set up with baron fireballs and stuff. As for polar.zip, it's
probably an iced version of Heretic (hence the name polar). Why would
they bother putting up Doom II since there is no reason to be stingy about
distribution as the game has been out for about 3 1/2 months commercially
now? Anyone have a commercial copy of Heretic yet?
M.E.
