some "o"'s in there just to mix it up a bit. The: "^ :piece at the end
was an obvious combination, so it was just a matter of finding a char
to connect the "a" to the "^". As it turned out, "v" was custom made
for that position.
WMHI: .:IHb. I Smooth shading can be created by using
MH[: .adAHHHI:. :H different chars to fade out at the edges,
HI: .:IHHHHHI:' .jIH instead of the anti-aliasing (which
Y: `:YHHI:' .:|IHM produces hard edges).
Good "outer" characters are: . , : ; ' `
For the transition from solid to outer edge: I H A U V T Y | i j d b
n a o [ ] :or basically anything that produces the desired effect.
Both line and solid techniques can be combined together, resulting in
a "comic book" look and feel. Each form of ascii art works well in
certain circumstances, so why not use this to your advantage. Line art
for the various outlines and small details, and solid art for large
dark areas.

5. 3 Dimensional Art
3D ascii art is basically an extension of SIRDS, where you can create
the illusion of depth on a flat surface. This is achieved by producing
two slightly different versions of the one picture, and placing them
a certain distance apart.
. . Focus Point
/ \
/ \ x Where the image appears
/ x \
--- --- __ The original pictures on the screen
/ \
/ \ /\ Where your eyes are looking
/ \
O O OO Your eyes
PLAN VIEW
Although the scale and angles are a bit off, the basic principle can
be seen from the above diagram (seen looking down). The two versions
of the picture are located on the screen, but you don't look there.
You need to focus on a point *past* the screen which produces a third
image at "x".
This resulting image occurs because of the way eyes work. They can only
focus on one "depth" at a time, and anything either further away or
closer becomes blurred. These "blurs" are just two different views of
the one object produced by the two eyes seeing different things.
Try this: stand three feet from a wall. Now hold two fingers up about
one foot from your face, and about 1.5 centimeters apart. Look between
your fingers, and focus onto the wall. Keep focus on the wall, but
look into the foreground at your fingers. You should see a ghost image
from both fingers converging into the center. The trick is to make the
two ghost images overlap each other resulting in (hopefully) one solid
image. This image should appear at a different level than the originals:
| | | | |
| | | | |
TWO FINGERS RESULTING IMAGE
The results from this experiment won't be 100% perfect since your two
fingers are likely to be different, but it is a good way to understand
the concept. With a little practice, you should be able to focus on real
3D pictures without too much effort.
--- --- Note that if you cross your eyes instead of using the
\ / above technique, you actually see the picture in reverse.
\/ This diagram shows the effect from above, and the resulting
/\ image will appear where the lines cross over. Since most
/ \ stereograms (STARE-eograms?) are created to go into the
/ \ screen, looking at them this way will produce an incorrect
O O vision (and is somewhat harder on the eyes).
That's the hard part out of the way, now a bit about how to create them.
Getting back to the little koala example (which is a perfect size for
this type of work), lets bring him into 3 dimensions.
X X Here I have placed two koalas 10 chars
___ ___ apart from each other. Generally, a good
{~._.~} {~._.~} distance would be between 7 and 15 chars,
( Y ) ( Y ) although you can use any distance you like.
()~*~() ()~*~() Values outside those bounds tend to be
(_)-(_) (_)-(_) difficult to focus on however.
The distance determines how much the resulting image sits "into" the
screen. If the distance is 0 (ie. no separation), the image is neutral
which means it appears -at- the screen. As the distance is increased,
the resulting image appears further -into- the screen.
By having many koalas laid out across the screen (all separated by the
same distance), the effect becomes slightly easier to focus on. Any
extra layers should then be added across the whole picture, with the
result being quite effective.
