Conway polyhedron operators
In your harnessMesh algorithmMIT
Build polyhedra from Conway notation: dual, ambo, kis, truncate, join, expand, ortho, gyro and snub applied to T, C, O, D, I, prisms and antiprisms, with planarizing relaxation. Use it for geodesic forms and gems.
What it takes and gives
- Entry points
- seed, dual, ambo, kis, gyro, apply_operator, conway, build and 1 more
- Parameters
- notation, relax
- Complexity
- O(size of the result) per operator, plus relax * faces
- Axes
- +Y up, metres
Limits. Geometry is approximate: new points start at centroids on the unit sphere and the relaxation only makes faces nearly planar; it does not produce canonical forms with equal edge lengths. Snub and gyro results are one of two mirror images.
