Survey of quickly generated point sets on S^2, examining their equidistribution properties and separation constants, with a focus on generating low-mesh ratio points.

Abstract

There are many ways to generate a set of nodes on the sphere for use in a variety of problems in numerical analysis. We present a survey of quickly generated point sets on S2, examine their equidistribution properties, separation, covering, and mesh ratio constants and present a new point set, equal area icosahedral points, with low mesh ratio. We analyze numerically the leading order asymptotics for the Riesz and logarithmic potential energy for these configurations with total points N < 50, 000 and present some new conjectures.
