This paper extracts some properties from the field of Computational Geometry and applies them to the design of Spatial Meshes. By means of two transformations: one inversive, the other projective, a way for making up polyhedra approximating spheres and other rotated second order surfaces (ellipsoids, paraboloids and hyperboloids), starting from a simple Voronoi Diagram, is shown. The procedure and its theoretical basis are related. CR TANGENT is a name proposed from its Spanish meaning. CR: “Cuádricas de Revolución”.
