  The structure of the SU(3) gauge-field vacuum is explored through
visualisations of centre vortices and topological charge density. Stereoscopic
visualisations highlight interesting features of the vortex vacuum, especially
the frequency with which singular points appear and the important connection
between branching points and topological charge. This work demonstrates how
visualisations of the QCD ground-state fields can reveal new perspectives of
centre-vortex structure.
