In geometry, circle packing is the study of the arrangement of circles (of equal or varying sizes) on a given surface such that no overlapping occurs and so that no circle can be enlarged without creating an overlap. The associated packing density, η, of an arrangement is the proportion of the surface covered by the circles. Generalisations can be made to higher dimensions – this is called sph… WebJan 26, 2010 · The random packing densities of ellipsoid, cylinder, spherocylinder, tetrahedron and cone are closely related to their shapes.
