Polyhedron polyhedra
In geometry, a polyhedron (plural polyhedra or polyhedrons; from Greek πολύ (poly-) 'many', and εδρον (-hedron) 'base, seat') is a three-dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices.

WebPolyhedron [{poly 1, poly 2, …}] is a collection of polyhedra poly i with or without voids and is treated as a union of poly i for geometric computations. Polyhedron [ { p 1 , … , p n } , data ] effectively replaces integers i that appear as coordinates in data by the corresponding p i .
WebFeb 17, 2024 · Play with the algebra and you'll see that the height of the polyhedron above the horizontal plane doesn't matter. The plane can be above the polyhedron, or pass through it, and the result will still be correct. So what we need is (1) a way to calculate the area of the base, and (2) a way to tell an "upper" face from a "lower" one.

WebFeb 11, 2024 · A polyhedron is defined as the intersection of finitely many generalized halfspaces. That is, a polyhedron is any set of the form $ \{x \in R : Ax \leq\ b \} $ I would like to understand this further. Given that $ Ax \leq\ b, Ax \geq\ b \leftrightarrow\ Ax=b$, a polyhedron can be a hyperplane.
WebA polyhedral dual is called a face-rectification or a birectification. In geometry, polyhedra are associated into pairs called duals, where the vertices of one correspond to the faces of the other. The dual of the dual is the original polyhedron.
