Sphere packing. (A) Target system: a digitized realization of a hard-sphere packing in which the spheres occupy 44.6% of space. The linear size of the digitized texture is NL = 100 pixels. (B) S2-alone reconstruction. (C) S2–F reconstruction. (D) S2–C2 hybrid reconstruction. All the reconstructions are associated with a final energy (error) E ≈ 10−11. (E) The (unconstrained) lineal-path function sampled from target and reconstructed realizations. Pixel size supplies the unit for the distance r.
