I just tried creating a small example to prove my point, and somehow
proved yours, hehe :)
Anyway, it seems you are right: we could convert the SSEGS of Doom
(convex structures) to Quake leaves because there would only be 1 ceiling
for each SSEG and only 1 floor. As long as the split-planes are chosen to
be vertical (ie. normal=(x,0,z)) -- as they would be if converted from
Doom -- the floors and ceilings would be the last planes to be insert
into the BSP tree and thus not intersect anything.

But couldn't the floor and ceiling surfaces be created using the convex
information from the SSEG structure?
(It's been awhile since I hacked Doom, so my terminology might be off...)

Yeah, I remember that one. But it didn't have quite the same idea as one
for Quake -- ie. letting us distribute levels... But I think you are
right, any file format not from id won't survive long :)
Anyway, id would probably analyse our fileformat and make some small
changes just to tease us... >;) (Things are bound to change with every
version up until registered, so why bother anyway?)

Only one floor/ceiling per xy plane: disallow multiple sectors to have
floors/ceilings with the same z-coordinates...
I think I misunderstood you. You mean that each sector only has one
floor/ceiling xy plane, right? (Which then also applies to SSEGs, which
hopefully could be our path through conversion hell.)

Which is exactly what id has been saying from the start... It can't be
_that_ hard to read the .txt's.

See?
Anyway, this doesn't clarify id's stand regarding the continuous
hacking/editing of the Quake Test 1 release. Where exactly will they draw
the line?

Yeah, yeah. Heard that one before :)

Subject: List of entity classnames
I hope this is not off topic, but I was wondering if anyone has compiled =
a list of all the entity classnames. So people can implement them in =
map editors. I have about 36 listed so far. That's just by looking over =
progs.dat a few times, I probably missed quite a few.=20
BTW, I'm having a little trouble understanding how to figure the =
distance between (0,0,0) and a plane. If anyone could enlighten me on =
this subject I be really grateful.
Thanks,

The plane equation is
Ax + By + Cz + D = 0
where (x,y,z) is any point in 3-space, (A,B,C) is the unit normal
(ie the vector perpendicular to the plane), and D is the distance
in 3-space to the plane.
Therefore, D is the value you desire.
If you want the distance between two points, it's just
sqrt(dx*dx + dy*dy + dz*dz) where (dx,dy,dz) is the vector difference
of the two points.
Hope this helps,

I have have this pretty much hammered out. I passed along my work in
this area to Raphael and I believe it will be munged into the next
release of the UQS. If anyone wants what I sent to him, speak up.
It is nothing really amazing but it is a lot of work to hack out
and you may want to save yourself from duplicating what I have
already done.

On this, I doubt that I will be of any help, sorry.
Have a great day,
