Spherical surface partitioning system - uses triangles extending along meridian lines in turn divided into further identical triangles

摘要

The spherical surface partitioning system divides the surface into identical triangles with their edges extending along the surface meridian lines, each in turn divided into 4 identical triangles. The outer edges of the triangles may have a curvature with a radius which is matched to the periphery of the sphere, the resulting triangle angles being 90, 60 and 45 degrees, to provide a total angle of 195 degrees. Pref. the individual triangles are made of steel reinforced concrete, glass, wood metal, or plastics. USE - For hall, container or lamp globe.
