Fig. 5.

The displacement vectors for each point of the female surface colour coded. Left column: the angle of the displacement vector to the surface normal is coded as red (outwards) or blue (inwards), with stronger colours coding smaller angle to the normal, i.e. displacement vector more normal to the surface. Middle column: the relative length of the displacement vector at each point colour coded as 33% percentiles, with the darker colours coding the upper percentiles. Right column: the change in (local) surface area coded as red (increase) or blue (decrease) and coded as 33% percentiles, with the darker colours coding the upper percentiles.
