Webthree non convex space-filling polyhedra (Eduard Bobik) It is well known that the stellated rhombic dodecahedron fills the space, but it is not obvious that the non convex rhombic dodecahedron above does the same. Its "center" belongs to six faces, two by two opposite and coplanar; this allows to say that its thirteen vertices define only nine ... Web$\begingroup$ Generating convex polyhedron from face planes is closely related because when the planes' normal vectors are consistently oriented, they provide a simple mechanism for determining whether points are inside or outside (as illustrated, for instance, in the code in my answer in that thread: see the argument to the RegionPlot3D example there). …
