Polyhedron projection

WebExplanation: In geometry, a polyhedron (plural polyhedra or polyhedrons) is a solid in 3 dimensions with flat polygonal faces, straight edges and sharp corners or vertices. The word polyhedron comes from the Classical Greek. A convex polyhedron is the convex hull of finitely many points, not all on the same plane. WebThe Waterman polyhedron projection is another variation of the “butterfly” projection that is created by unfolding the globe into eight symmetric, truncated octahedrons plus a …

These are projective analogs of spherical polyhedra – tessellations of the sphere – and toroidal polyhedra – tessellations of the toroids. Projective polyhedra are also referred to as elliptic tessellations or elliptic tilings, referring to the projective plane as (projective) elliptic geometry, by analogy with spherical tiling, a synonym for "s…

WebA possible way to do this is tracing the silhouette edges of the polyhedron and projecting them to a 2d polygon only at the end of the process. A silhouette edge (in your context) is defined by its neighboring facets having one upwards and one downwards normal (i.e., one positive normal z-coordinate and one negative).

A polyhedral map projection is a map projection based on a spherical polyhedron. Typically, the polyhedron is overlaid on the globe, and each face of the polyhedron is transformed to a polygon or other shape in the plane. The best-known polyhedral map projection is Buckminster Fuller's Dymaxion map.
