Write your reply.

assistant: There is no truth to that at all. Whatever you read in PCGPE, ignore it.
Doom works like this.
Say you had a level that looked like this where p = player;
        +--------------+
        |              |
        |              |
        |     p        |
        |              |
        |              |
        +--------------+
Note that player can be facing in any direction, it doesn't really matter in
the direction as you simply rotate all vertecies around the current player
angle (although you can get some optimizations uses this).
Anyway, if we were to render this room, all you would need to do is to just
render the walls in any order you want because in any direction, in any place
we are, the walls will never occlude. (These rooms are oftenly refered to as
"Atomic Areas").
As you probably know, Doom has quite more complex levels/rooms than this. If
you had a room which would occlude, Dooms engine grabs the level, and tries
o
split it into atomic areas. (areas that will never occlude)
Like this:
           +-----------+
           |   A       |
           |           |
            \sssssssss/
            /         \
            |   B      |
            |       p  |
            +----------+
If you tried to render the walls in any order, in some position it will
occlude. So you must split the map into two atomic rooms. ("s" is the split
line).  The bsp tree for this would look like:
                 s
                / \
               A   B
If player is on the left side of the head node (the splitting line, which is
s)
then go right, else go left.
So if you were on B, render area A, then B. And if you were on A, then render
B, then A. That's basically all it is, however, the bsp trees can get very
complex at times. (Quake uses a 3-space bsp engine, therefore a split line
would become a split plane).

assistant: On (07 Aug 97) Mathieu Bouchard wrote to Jerry Coffin...
[ ... ]
I _was_ talking about basic mode 0 reads and writes.  In mode 2 you
can reduce the number of reads and writes, but to do so, you have to
mask the correct bits with some I/O port writing.  Depending on the card
involved, and the type of drawing you're doing, this may or may not be a
win.
For instance, if you're drawing a vertica or horizontal line in a solid
color, this can be wonderful: you set the bit masking once for the
entire line (if it's vertical) or nearly the entire line if its
horizontal (the ends may require masking off some pixels) and then do
one write per pixel.  Depending on exactly how you do things, in a
horizontal line, you can even write 8 pixels per memory write, obviously
a BIG win.
However, if you're doing more or less random drawing of various lines
and pixels and such, things get a lot less rosy in a hurry -- for
instance, in drawing a line at a 45 degree angle that's made up of
alternating dots in red and green (or whatever two colors you prefer,
more or less) you end up having to change the color register and the
bitmask register every time you write a pixel.  In this case, you have a
couple of port writes plus one memory write per pixel.  Depending on the
card, this may or may not be faster than multiple memory reads/writes
per pixel.
Any way you go at it, whether you're talking about multiple memory hits,
or multiple port hits, you're still looking at things being slower than
a single memory write.
    Later,
    Jerry.

assistant: Hello all :)
I've recently jumped into the fun world of PC sound programming.  I read
somewhere in my SbPro manuals that the card has 4 sound channels, either
2-left 2-right, or all 4-mono.  Any coder with an IQ >2 would see the benefit
of using these hardware channels instead of mixing the stuff in software..
he
question is:  How do I tell the SB which channel(s) to use ?  I get the
feeling this is going to be like Vesa programming, replacing the video banks
with sound banks or something..
Any info, or directions toward some detailed info would be greatly
appreciated.

smaller is also faster here...
i use a 38-byte differential generator which provide accurate tables

of bits per coefficient and lots of harmonics; and then, restoring at a
16x16 scale what was at 8x8 scale, for example.
I'm kinda curious about how fractal compression work...
there was some fuss about it a few years ago, but i didn't have such

i suppose you're talking about SoundBlasters 1.0 through 16 (5.0 or 6.0

there is only one channel on the sb, two if it's a stereo (3.0 and
better), but in that case, those two are linked at the same frequency.
you have to mix 'by hand'. write a program that shrinks/stretches
soundsamples at the desired speeds. that's how .MOD's are played on
SB's, usually.

Write your reply.

assistant: in 256-color mode too. doesn't depend on the 16/256 color distinction,
rather on the use of planes.
I'm wondering, do non-plane 16-color modes exists?... it would make
sense.
hmm I'll have to check about this, i'm curious about the 16 one; 4,
figured that one easily; maybe there's a 1-read too, but i'll have to
browse my docs...
how often do you GetPixel??
Besides, thinking you were talking only about the 16/256 color
distinction, thought that everywhere a planed 256 is fast, a planed 16
is twice as fast because it's twice less data; but there is the
disposition scheme consideration... a pixel in 16-color is on all
planes at once while it's on 1 plane in 256-color.

Oh, actually, it IS wide known that DOOM uses BSP trees, and I can't quite
see how they'd fit in with raycasting, because raycasting basically takes
care of all the hidden surfaces etc for you, as that's what the algorithm is
all about, drawing what you can see by tracing invisible rays through maps

So, yeh, I think it doesn't use raycasting..

assistant: the most common `DOS' (i.e. MS DOS) has a non-reentrant int 21h. Some
improved clones (NW DOS, OpenDOS, PCMOS/386 ?) don't have this problem,
but i guess we have to support the `masses', so...
If you don't have the interruptlist by Ralf Brown, either get it now or
read it through http.
basically, you have to check for a certain flag (`dos busy'?) to be
zero, and it's more complicated than that, you have to check a 2nd flag
because braindead DOS doesn't set that `dos busy' flag in case of an
INT 24 signal. You have to delay your disk accesses until both are
cleared, and it can be quite a pain in the arse if you know what i
mean.
For details, see that interruptlist, and browse through it.
