# A flat letter turns into an object, one face at a time

> Pull an offset back at a fixed angle, shade the side, highlight the top edge — a name becomes solid without anybody drawing a vanishing point.

Three versions of the same letter, in a row. The first is flat, an outline and nothing else. The
second has a block pulled back behind it at a steady angle, turning the outline into a solid. The
third shades that block's side face darker and lays a thin bright line along the top edge.

Three stages, one shape. By the third, it isn't a letter drawn on the wall — it's a letter that
happens to be sitting in front of it.

## What actually turns an outline into a solid?

A second copy of the outline, offset back at one fixed angle and joined to the first with
straight connecting lines.

That's the whole trick: draw the letter, draw it again shifted diagonally, and connect the
corresponding corners. The connecting lines become the sides of the new solid, and because
they're all parallel and all the same length, the shape reads as one object seen from one
direction rather than a collection of separate parts. It's [the same offset the drop shadow
uses](/stories/the-drop-shadow-does-the-work), just pulled far enough back and finished
with sides instead of left as a flat shape behind the letter.

## Why does the angle have to stay fixed?

Because the angle is standing in for a light source and a viewpoint, and both of those have to
agree across the whole word.

A single letter can be extruded at any angle you like and still read correctly, because there's
nothing else in the frame to compare it to. The moment a second letter sits next to it, the two
extrusions are implicitly claiming to be lit and viewed the same way. Forty-five degrees is a
common choice because it's easy to hold by eye without a ruler, not because it's the only angle
that works — what matters is that whichever angle gets picked, every letter in the name commits
to it.

### What happens when two letters disagree

A name where one letter extrudes down-right and its neighbour extrudes straight down doesn't read
as two styles — it reads as one letter pasted in from somewhere else. The eye doesn't parse
"different angle," it parses "wrong." That failure is more visible here than almost anywhere else
in the alphabet, because extrusion is the convention that's explicitly claiming to describe real
space, and real space doesn't have two lighting directions in the same shot.

## Is this real perspective, or something else?

Something else — it's perspective run by a fixed rule rather than constructed from a vanishing
point.

Actual perspective converges: lines pulled back from a shape all aim at one point in the
distance, and shapes further away get smaller. This convention never converges and never scales —
every extruded face is the same depth regardless of where the letter sits on the wall. It borrows
the *reading* of depth (a side face, a highlight catching notional light) without borrowing the
construction. That's closer to an axonometric drawing than a vanishing-point one, and it's the
right trade for something painted fast, upright, and usually close to eye level rather than
receding into a scene. It sits alongside [the fuller stack of skeleton, fill, shadow and
keyline](/stories/outline-fill-and-forcefield) as another layer answering its own
question, not a replacement for any of them.

## Is a technique like this anybody's property?

No — extrusion at a fixed angle is a method for building a shape, and a method isn't owned by
whoever used it first.

Painting something illegally doesn't remove the painter's copyright, and none of that reaches the
underlying technique regardless. VARA, the 1990 US federal copyright amendment, protects a
finished work of "recognised stature" from destruction and protects the artist's right to be
named — at 5Pointz a jury found the developer had violated it when the walls were whitewashed
with no notice, and the court awarded about $6.7 million to the artists, affirmed on appeal. A
letterform convention like this one isn't ownable the way a specific letter is; nobody owns a
45-degree extrusion any more than anybody owns italics. A particular alphabet, drawn in a
particular hand, is that writer's.

## Does it print well?

Yes — every face in this construction is already a single flat tone, which is what a print wants
regardless of how many stages get shown.

The front face, the side face and the highlight are three distinct values with hard edges between
them, no blending required anywhere. What has to survive is the registration between those edges
at fabric scale — a highlight line that drifts even slightly off the top edge stops reading as
light and starts reading as a stray mark. Warm grey, cream and soot black hold that contrast at
any distance a chest print is seen from, and three inks is enough; a fourth would just be another
edge to keep aligned. It's the same restraint [choosing between six different
fills](/stories/what-goes-inside-the-letter) rewards — one clear decision per surface
beats several competing ones.

## How do I get one made?

Show the letter or name at [JustOG](/) and how far back the extrusion should run. Pick a
direction, drag the crop frame, see it composited on the real garment, and it's made to order and
shipped.

Designs other people have published are in the [shop](/shop).

Nobody drew a horizon line. The letter just agreed to sit at one angle and stopped being flat.
