ANIMATIONS 1-3. Pit-to-pit transition movies depicting deformation from one pit to another in chronological order. The three animations are in lateral, ventral, and anterior views. The animations begin with the mean pit 91 shape (gold), deform to the mean pit 2051 shape (blue), then to the mean pit 13 shape (green), and end with the mean 61/67 shape (red).

ANIMATIONS 4-6. Deformation of the global mean landmark configuration along PC 1, traveling 0.15 units in the negative direction. Deformations have been doubled for ease of visualization.

ANIMATIONS 7-9. Deformation of the global mean landmark configuration along PC 2, traveling 0.15 units in the negative direction. Deformations have been doubled for ease of visualization.

ANIMATIONS 10-12. Deformation of the global mean landmark configuration along PC 3, traveling 0.15 units in the positive direction. Deformations have been doubled for ease of visualization.

ANIMATIONS 13-15. Deformation of the global mean landmark configuration along PC 4, traveling 0.15 units in the negative direction. Deformations have been doubled for ease of visualization.
