Visual inspections of the deformation between population and one of the Base or Reference models. The population model (black) is shown in mesh form, and the Base (red) or Reference (blue) models are shown as solid forms. Figures 4a and 4c represent each model before the deformation, while figures 4b and 4c represent each model after the deformation.
