Shape deformations according to the first PLS sep dimension. The sequence of surface representations (from left to right) as deformations of the average shape of the two blocks, bill (a) and cranium (b), correspond to increasing scores of the first PLS sep dimension in Figure 9. The surface morphs differ from its neighbors by equal multiples of the standard deviation of the actual variability. The first and last column is extrapolated by 4 standard deviations. Major covariation between blocks lies in relative bill- and palatinum length (a) and in the relative position of the cranio-facial hinge (b).
