Icosahedron face-crossing cells

global

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

Icosahedron face-crossing cells illustration — ▪ Rendered from the real conversion/geometry code.

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

H3 → exact polygon exact
H3 → inscribed circle conservative
