• sortPolyBondsByStereo

  void sortPolyBondsByStereo(SimpleNode atom, SimpleNode ref, javajs.util.T3 center, SimpleEdge[] bonds, javajs.util.V3 vTemp)

  Sort bond array as ccw rotation around the axis connecting the atom and the reference point (polyhedron center) as seen from outside the polyhedron looking in. Since we are allowing no branching, all atoms will appear as separate components with only numbers after them. These numbers will be processed and listed in this order.

  atom -

  ref -

  center -

  bonds -

  vTemp -
