Icosahedron face-crossing cells

Global

Cells spanning two icosahedron faces are distorted; edges are not symmetric and area varies.

Detection

Compare edge lengths / inscribed:circumscribed ratio against the resolution norm.

Mitigation

  • Densify edges
  • Compute circles from the true boundary, never from a nominal edge length

Affected conversions

  • H3exact polygon
  • H3inscribed circle
