used, but now I use "H" because I like its consistency. Other people
|
prefer "8", so it's really just a matter of personal taste. Indeed,
|
remapping an image from one type into another is quite simple, and should
|
not affect the picture at all.
|
Different effects can be created by varying the chosen texture over
|
various sections of the picture (shading). The choice of character can
|
also be based on the subject matter, for example, if money were involved
|
the obvious choice would be a "$". Try to avoid using "*" though, as it
|
looks a bit cheesy (imho).
|
Once the basic shape is defined with the chosen character, the anti-
|
aliasing process is next. The most used chars are:
|
d b P F 9 V T Y A U _ , . - * ^ ~ " ` ' n a o l L j J k [ ] ( ) : \ / | !
|
Each character has a purpose based on its shape, although there are
|
cases where no character will produce perfect results. In these cases,
|
you either have to make do as best you can, or remodel that particular
|
area of the picture, thus giving you a fresh approach.
|
Going back to the earlier "curve" examples, here they are in solid form:
|
.adAHHHAbn. JHH
|
dHHHHHHHHHHHb _.adHHH
|
dHHHHHHHHHHHHHb ,AHHHHHHH
|
HHHHHHHHHHHHHHH dHHHHHHHHH
|
VHHHHHHHHHHHHHP JHHHHHHHHHH
|
YHHHHHHHHHHHP _.adHHHHHHHHHHH
|
"^YUHHHUP^" HHHHHHHHHHHHHHHH
|
"~"
|
SPHERE CURVED HILL
|
It's important to get a good understanding of how best to use the
|
characters. The basic forms are as follows:
|
_,.aomdAHAbmon.,_ For the upper curves.
|
"~^*YUHUP*^~" For the lower curves.
|
The characters: d b P :are all extremely useful, but there is no
|
equivalent character for bottom/left. There is, however, four chars
|
available which do a decent job: T Y V 9 .The 9 works well for *some*
|
char sets, but generally it has a big hook at the bottom so isn't
|
quite so useful.
|
Notice how I've used "A" and "U" to smoothen the transistion from "H"
|
to "d"/"b" (and "Y"/"P" respectively) even though the effect is quite
|
subliminal. A minor detail, but it does help. I don't often use "_"
|
in these types of pics because of the way it touches the top of the
|
"H". It does come in handy sometimes though.
|
Side curves require more of an "on the spot" approach. The chars:
|
l [ ] : j i :all come in handy when trying to smoothen out vertical
|
curves, and I've also seen "(" and ")" used (although I wouldn't use
|
them myself). Consistency in contrast is very important.
|
Adding details using the solid ascii technique is a bit harder than
|
in line art because there isn't the same number of possible choices
|
for each position. The letters: a n o :are all very useful because
|
they are nice "solid" chars which only occupy the bottom half of the
|
character space, but there is no good alternative for the top half.
|
dHF^^^ See how the bottom arm fits in with the solid
|
dHP appearance of the main part, yet the "^" (which
|
dHBooan is the closest char available) doesn't look so
|
beefy. Even the "^" varies across different char
|
sets, so that leaves just: " ~ : which are of no use at all. In that
|
particular case, it is necessary to expand the picture by one line:
|
anpoan Note the use of the "p" to make the effect just
|
dHP that little bit more effective. An "r" could also
|
dHP work well at the end of each arm. Purely cosmetic
|
dHBooan though. Note that if you're using "M" or "W", then
|
"m" and "w" can be used to keep it consistent.
|
Details aren't always as simple as that example though (unfortunately).
|
HHHH aann .aoon.

HHHHHHHHHH dHHHHHHb .adHHHHHHh,
|
HHHHHH ~^VHHHP ~^VHHHP

|
START HALF WAY FINISHED
|
The different steps can be seen here. Starting by roughing out the shape
|
(a wizards head incidentally) using the chosen character. Next, go over
|
all the edges making all the obvious replacements. That means using:
|
d P b Y V a n :plus the occasional: " ~ :if there's an obvious place for
|
it. Just enough to give it some shape.
|
The final stage requires a bit more work. Start with "A" and "U"/"V",
|
and then the rest is purely experimentation. The "S" was chosen because
|
it seemed to have the right shape, although there are many chars which
|
could really go there.
|
The curve section at the back required quite a lot of work. An "a" seems
|
to be the best opposite of "n", and for long stretches, I like to use
