Polyhedrons
PNG
rotate by dragging on polyhedron, rescale by scrolling over canvas
The specification consists of a space-delimited series of polyhedral recipes. Each recipe looks like:
[op][op] ... [op][base] no spaces,
just a string of characters
where [base] is one of
T - tetrahedron
C - cube
O - octahedron
I - icosahedron
D - dodecahedron
PN - N-sided prism
AN - N-sided anti-prism
YN - N-sided pyramid
and op is one of
kN - kisN if no N then general kis
a - ambo
g - gyro
d - dual
r - reflect
e - explode (equiv. to aa)
b - bevel (equiv. to ta)
o - ortho (equiv. to jj)
m - meta (equiv. to k3j)
tN - truncate (equiv. to dkNd)
j - join (equiv. to dad)
s - snub (equiv. to dgd)
p - propellor
also, some newer, experimental operators
l - stellation
nN - insetN
xN - extrudeN
z - triangulate
there are also two "refinement" operators for the
canonicalization of the polyhedral shape, mainly intended for making
the more traditional, convex polyhedra more symmetric
KN - quicK and dirty canonicalization, it can blow
up, iteratively refines shape N times.
