Facial shape affects self-perceived facial attractiveness
Fig 2
3D PCA graph displaying facial variation according to sex (in SD units), in the entire sample, as explained by PC1 (20.9%), PC2 (15.1%) and PC3 (9%).
The corresponding 3D facial morphings represent the average female (red) and male (blue) facial shapes. A best-fit superimposition (upper right) reveals the surface differences in facial shape between males and females and the color-map (lower right) displays the magnitude of those differences, as distance of the female from the male face (positive: forward).
