Some examples of threedimensional shapes are cubes, rectangular solids, prisms, cylinders, spheres, cones and pyramids. Drawing a correspondence between the nature of a defect and a specific geometric property of the material space not only illuminates the underlying structure of defects in solids but also provides an unambiguous way to represent defect densities within a physical theory.
