PNG OBJ VRML2

rotate by dragging on polyhedron, rescale by scrolling over canvas

This is a toy for building complex 3D polyhedral shapes from simple ones by "recipes". A recipe looks like:

[op][op] ... [op][base] no spaces, just a string of characters

where [base] is one of

and op is one of

also, some newer, experimental operators

There are more complicated, parameterized forms for k and n:

there are also three "refinement" operators for the canonicalization of the polyhedral shape, mainly intended for making the more traditional, convex polyhedra more symmetric

these will mangle the geometry of the weirder polyhedra, which can occasionally result in interesting results!

3D Printing

You can export these shapes in forms appropriate for 3D printing by shapeways. Export in VRML2 format to preserve face colors if you want to use their colored fused-sand process.
