Each picture colours only what its last step made. Click a word to open it in the playground.

Words

`x[+z] C`	read right to left; the seed is last
`x[sel]`	the faces it acts on; all if left out
`x(0.6)`	numbers; any left out take the defaults
`x{roof}`	label every face this step makes
`x^3`	repeat the step
`a + b`	shapes side by side: several bodies
`name = word`	a name for a shape, or for steps
`name(h) = word`	steps with a parameter, used as `name(1.2)`
`name[s] = word`	steps with a selector, used as `name[top]`; all if left out
`; note`	a comment, to the end of the line
`export "f.obj" word`	write the shape as OBJ

Seeds

C(w, d, h)

box, 2 × 2 × 2

T(r)

tetrahedron

O(r)

octahedron

I(r)

icosahedron

D(r)

dodecahedron

P5(r, h)

prism, any n ≥ 3

A5(r, h)

antiprism

Y5(r, h)

pyramid

T O I D have circumradius √3, like the cube.

Modelling

x(1) extrude

a block on each face: side top

lift(1)

one block per connected region

i(0.3) inset

a face inside each face: rim inner; below 1

k(0) kis

a tent on each face: tent

h bridge

a tube between two faces: tube

scale(0.5)

each region about its centre

push(0.5)

faces along their normals

merge

undo a kis: merged

flip

turn the edge between two triangles

Symmetry

mirror[seam]

join the shape to its reflection across the seam: build half, get the whole

Transforms

move(x, y, z)

shift; numbers left out are 0

turn(z, y, x)

degrees about each axis, z first: counterclockwise from above

stretch(x, y, z)

along each axis; numbers left out are 1

Without a selector, the whole shape; with one, the picked faces' corners. turn and stretch act about each region's centre, and each body is a region of its own.

Copies

array(n, x, y, z)

n in a row, each moved (x, y, z); 2, 1, 0, 0

spin(n)

n around the vertical through the origin; 6

Conway

d dual

a face for each corner: vertex edge

a ambo

cut every corner to the middle

t(0.3) truncate

cut every corner; up to 0.5

g gyro

pentagons in a pinwheel: face

r reflect

mirror across x = 0; every face

s snub

one of the letters made from others:

`n` kd	`z` dk	`j` da	`e` aa
`o` daa	`m` kda	`b` ta	`s` dg

With a selector they act on part of the shape: d[top] x[+z] C

Selectors

`+x -x +y -y +z -z`	faces facing that way
`top roof`	a role, or a label
`all new`	every face; what the last step made
`n4 #3`	faces with 4 corners; face number 3
`a&b a\|b`	both; either
`!a ~a`	not; the faces bordering `a`
`( )`	grouping; `! ~` bind tightest, then `&`, then `\|`
