One of the first commercially available 360 cameras happened to be the Ricoh Theta series, and while it is a novel first attempt, it leaves out much to be ironed out.
Brandt Matrices and Theta Series Over Global Function Fields
Given an arbitrary function together with a fixed place, then construct a family of theta series from the norm forms of "definite" quaternion algebras, and establish an explicit Heck-module homomorphism from the Picard group of an associated definite Shimura curve to a space of Drinfeld-type automorphic forms.
However, Sloane and Teo in [21] reported a magnificent but complicated mathematical formulation for theta series and magic numbers in closed packed clusters (see also Appendix A) which yet few applications are known in which; one exactly can use this information in materials science researches.
