At the end of the 17th century, flat wood vaults were invented by Joseph Abeille (pronounced, Zhō-sĕf Ah-bāy,) composed of interlocking, load-distributing timbers, arranged as a reciprocal frame • The original Abeille’s vaults, designed for a flat roof, are adapted to model curved surfaces of architectural applications • Geodesic reciprocal-frame spheres are currently referred to, in mathematical & architectural journals, as "nexorades" • Several nexorade articles are available online, and can be found by Googling the term, "nexorade"

This particular model depicts a frequency-4 icosahedral geodesic tessellation, using 34.5° nexorade-rotation and 24° block side-slope, as presented in the article • Such spherical vaults can be constructed with no mechanical connections between bricks, relying on friction & compression forces, alone, thanks to the interweaving of the blocks • The cross-section of each gold brick is an isosceles trapezoid • Only 8 different gold-brick configurations are used, to replicate over the entire surface (480 bricks; total)

Modeled in SketchUp • Rendered in Kerkythea

Thats certainly eye catching

Ha!

The stone & steel versions, I rendered to depict realistic constructs.

This one, however, was all about eye candy.... :nod:
