A solid bounded by polygons.

polyhedron

(ˌpɒlɪˈhiːdrən)
n, pl -drons or -dra (-drə)
(Mathematics) a solid figure consisting of four or more plane faces (all polygons), pairs of which meet along an edge, three or more edges meeting at a vertex. In a regular polyhedron all the faces are identical regular polygons making equal angles with each other. Specific polyhedrons are named according to the number of faces, such as tetrahedron, icosahedron, etc
[C16: from Greek poluedron, from poly- + hedron side, base]

Let the reader picture to himself a series of visages presenting successively all geometrical forms, from the triangle to the trapezium, from the cone to the polyhedron; all human expressions, from wrath to lewdness; all ages, from the wrinkles of the new-born babe to the wrinkles of the aged and dying; all religious phantasmagories, from Faun to Beelzebub; all animal profiles, from the maw to the beak, from the jowl to the muzzle.
Others, like field hospital (a normative metaphor Francis uses to describe today's church), encounter (which Francis describes as a "polyhedron" of human connection), and the more lighthearted sourpuss (on people so concerned with rule-following that they lack Christian joy) take us beyond the headlines and offer a wider view of Francis' vision.
One solution consists of maintaining the system trajectory within A-contractive controlled invariant polyhedron set defined in the state space.
If the geometric object is a polygon without a curve or a polyhedron without a surface, the implicit function is accurate; otherwise, the implicit function approximately expresses the geometric object.
