im-buckyball

Describe geometry, and eventually produce an agular directive containing d3.js code to produce a trucated icosahedron, a.k.a buckyball, soccer ball

TODO

• encapsulate pre-calculate
• simplify executable (buckyball.js)
• convert to gist, and post to mbostock's http://bl.ocks.org/
• Make an angular directive ng-buckyball. Review this youtube talk on Angular with D3 .

Geometry

• Icosahedron - truncated icosahedron
• projection = d3.geo.azimuthal().mode("orthographic")
• Spherical clipping: path(circle.clip(d));

Precalculate

• figuring out pentify

Changes

Trying to evolve icosahedron-3055104.html turned out to be a dend end.

Started from icosahedron-arcs-3061181.html to get the sperical projection and clipping, and re-did the geometry from scratch, math was tested in precaclulate.js
