The direct calculation of the three-dimensional structure of hadrons is a long-standing goal for nuclear physics. These calculations have only recently become possible, and the first physical pion mass calculations of parton distribution functions (PDFs), which encode the longitudinal momentum structure of hadrons, have marked the advent of a new era in first principles' calculations of hadron structure. I introduce these recent developments and then summarise the Hadstruc Collaboration's on-going effort to extract the quark and gluon PDFs of the nucleon directly from lattice calculations via the reduced pseudo-distribution approach.
