Nearpt3 - Nearest Point Query
Nearpt3 is a pair of subroutines to find nearest points in E3. Preprocess takes a list of fixed points, and preprocesses them into a data structure. Query takes a query point, and returns the closest fixed point to it.
Nearpt3 is very fast, very small, and can process very nonhomogeneous data. The largest example run on a laptop computer was St Matthew from the Stanford Digital Michelangelo Project Archive, with 184,088,599 fixed points.
