Default Nearest Point Algorithm

In order to interpolate a solution of a 3D structured or unstructured mesh (Source mesh) on to an arbitrary surface (target mesh) cutting the solution domain I am looking for an efficient software/public domain package solving the nearest neighbour problem (Look for n nearest neighbours of every target mesh point in the source mesh). Comments on effiency will be extremely helpful.

Thanks
