A novel method due to Misner improves on traditional techniques by avoiding the need to cover the sphere with a coordinate system appropriate to the grid geometry. This paper will discuss Misner's method and suggest how it can be improved by exploiting local regression techniques.14 pages, 4 figuresGeneral Relativity and Quantum CosmologyComputational Physicstext
