Hard disks in a three dimensional space [1] (also known as platelets or hard-cut spheres) are sections of spheres which have some thickness , obtained by slicing off the diametrically opposed caps of a sphere at a distance from the equatorial plane. Hard cut spheres have been used to study the isotropic-nematic phase transition [2] in liquid crystals, along with the columnar and cubatic phases [3][4].
