Actually I don't know how DOOM does it I only know how we did
it on our engine.

Actually you can interleave the floor texture so that each row
starts on a 256 byte boundary and use hardware wrapping for the flats.
IMHO, this is why Carmack doesn't allow you to mess to much with these,
because they have to be interleaved properly.

We (Neural Storm) have written a very similar engine except
for (see below).

Okay here we go. <propoganda mode on> We wrote a game here
that does the same sort of thing. It's called Radix: Into the Void and
it's coming out next month. It uses a doom engine EXCEPT any sector
can be sloped/tilted at ANY ANGLE. This mean you can have ramps etc
anywhere you want any way you want. They can be sloped almost straight
up or almost flat. It's a flying game where you fly through the corridors
and dogfight etc. 4 player net + modem and null modem support. It's
kick ass with the mouse (IMHO). To get back to editing, I wrote the map
editor for Radix (didn't think I'd be on this list for nothing.), as well
as plenty of the game, including the node builder. And YES we will
be releasing an editor for it, free of charge, but don't expect support
(and bug killing wasn't the hugest priority). <propoganda mode off>
Anyway as someone else pointed out this thread is
getting dangerously off topic so if anyway wants to email me go ahead.
L8r,
Jon

Sure, but it's not as detailed as Doom, a few hallways with a kinda
choppy movement (at least the x-degree). I didn't notice any spectaculary
light effects. Pardon me, but I think the Doom engine is faster too.
But don't count too much on this, I played the alpha (?) version just
a bit (I hope you added the cockpit-view) and found it not very smooth.
[Don't panic, I don't have the game, I just played it a few days ago]
>This mean you can have ramps etc anywhere you want any way you want.
Sure, but it has a kinda 'angular' look, e.g. Descent is much 'softer'.
Some slanty ramps doesn't make it so much better than Doom too.
But this is going too far, I will stop posting with this thread herewith.

Hmmm... Once I loaded up level 27 in DOOM ][ and hit the pause button for
some reason, but I hit pause while it was in the middle of redrawing. You
know that slime lake in the middle of the first room that you can't see? Well,
at the moment I paused the entire floor from the back of the slime lake up to
my feet was filled with it, sort of like there was some really funky HoM effect
somehow. But it drew the floor that was farther away and lower first. Perhaps
it chooses to draw lower floors first if the floor is below eye level and
higher ceilings first if the ceiling is above eye level.
