Sphere circumscribing a tetrahedron
Web7. dec 2009 · For the convex case (no dents in the surface which cause surfaces to cover each other) and a triangle mesh, the simple solution is to calculate the center of the polyhedron and then connect the three corners of every face with the new center. If you don't have a triangle mesh, then you must triangulate, first. Delaunay triangulation might help. WebThe circumscribing sphere is defined as the sphere with center at the ge-ometric center and radius equal to the distance from that center to any spacecraft (thus, all 4 spacecraft lie on its surface). One-Dimensional Parameters The following parameters are useful for comparing the true tetrahedron against an ideal (regular) tetra-hedron.
