Elliptical domes offer interesting alternatives to hemispherical envelops. In hemispherical domes the ratios between the spans and rises are always 2:1. Elliptical domes can be stretched or squashed.

The drawings show a well-proportioned geodesic elliptical dome, modelled on a actual melon! The ratio between its major and minor axes is 1.44:1. It has bilateral symmetry, the breakdown is a 4-frequency octahedral symmetry.
