Fixed-radius near neighbors

In computational geometry, the fixed-radius near neighbor problem is a variant of the nearest neighbor search problem. In the fixed-radius near neighbor problem, one is given as input a set of points in d-dimensional Euclidean space and a fixed distance Ξ”. One must design a data structure that, given a query point q, efficiently reports the points of the data structure that are within distance Ξ” of q. The problem has long been studied; cites a 1966 paper by Levinthal that uses this technique as part of a system for visualizing molecular structures, and it has many other applications. (Wikipedia).
