WebPolyhedrons. A polyhedron is a 3-dimensional figure that is formed by polygons that enclose a region in space. Each polygon in a polyhedron is called a face. The line segment where two faces intersect is called an edge and the point of intersection of two edges is a vertex. There are no gaps between the edges or vertices in a polyhedron. WebJun 5, 2024 · The sphere inscribed polyhedron should be convex too. Also, preferrably no two distinct faces of the polyhedron should be coplanar, otherwise they can be combined to a single face. In this sense, the Triakis tetrahedron is indeed a counter-example to my question. There are inscribed polyhedra equivalent to it, but they are either not convex or ... fitzkee candy

WebJul 8, 2013 · You might consider trying to find the (bounding) sphere (origin + radius) that encloses the polyhedron, and test to see if that is intersected first. Or an axis-aligned bounding box (AABB). Then you can move onto the more expensive polyhedral test - which might require testing against each 'front-facing' triangle. WebMove vertices to equalize edge length over the whole polyhedron; Move vertices to make edges tangent to unit sphere; Move vertices to lie in the total least squares planes of the faces they are part of; Spectral Realization.

WebMay 12, 2014 · A uniform polyhedron is a 3D solid that is bound entirely by facets whose edges are all exactly the same length and whose vertices are all equidistant from its geometric centre. This essentially means that all its facets are regular polygons and all its vertices lie on the surface of a bounding sphere. WebOct 21, 2015 · Something of the nature: Imagine a shape/polyhedron inside a sphere. Now map out or project the vertices's and edges of the polyhedron onto the sphere. It is like having the shadows of the edges and vertices's being mapped onto the wall of the sphere.
