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). |

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 |
