Fig. 4
(A) Facial DA based on polygonal surface analysis for right- and left-side eyedness in males and females separately. The DA is visualised using colour-coded 3D maps. Warm colours (red) show protrusive areas, cool colours (blue) show retrusive areas. Areas showed in green are asymmetrically neutral. The threshold on the asymmetry scale was set to 0.002. (B) Differences in DA between right- and the left-eyed individuals calculated by the polygonal surface analysis and visualised by colour-coded 3D maps. Red shades show protrusive areas in left-eyed individuals, blue shades show protrusive areas in right-eyed individuals. Areas in white are asymmetrically neutral. (C) Facial DA based on 3D landmark analysis, visualised by wireframe graphs in both sexes. The scaling for the DA was 10×. The grey lines show an ideally symmetrical shape in each tested group. The blue lines (for males) and red lines (for females) show the shape of specific DA next to the symmetrical shape in each group. The green arrows show the range and direction of shifts in facial DA from the ideally symmetrical shape mean. DA visualised by: colour-coded maps in Morphome3cs II software = A, B; landmarks in MorphoJ 2.0 software = C. M males, F female, R-eye right-side eyedness, L-eye left-side eyedness, B-eye both eyes, R right-side eyedness, L left-side eyedness.
