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. |
