  State-of-the-art lattice QCD simulations enable the evaluation of nucleon
form factors and Mellin moments with controlled systematics, yielding results
with unprecedented accuracy. At the same time, new theoretical approaches are
allowing the direct computation of nucleon generalized parton distributions. We
review recent lattice QCD results on these quantities that are paving the way
for extracting a wealth of information on the 3-dimensional structure of the
nucleon.
