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).

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.
