All the shapes! When I was working in space science we experimented with using Hierarchical Triangular Meshes but we ended up not really needing the faster indexing it offered since most of our processing was done in small portions of the sky at a time anyways.

I use a Hierarchical Triangular Mesh for indexing gamma ray events from the universe. The data is partitioned in the database according to it's HTM id. http://arxiv.org/pdf/cs/0701164.pdf Currently I use this for indexing ~11 billion gamma ray events. Researchers typically supply a region in the sky, a search radius, and some cuts (energy, event quality, etc...)
