[comp.graphics] Any info on the geotangent dome

hergt@decnix.dec.com (ZK03-3/Y25 (X/H5-3X39); DTN 381-0813) (09/14/89)

Does anyone know anything about the geometry behind the combined
pentagonal and hexagonal tiling of a circular based, ellipsoid
surfaced dome?  I have heard the term GeoTangent dome used.
References?
