Animation: Rigid Morphing with large rotations: For small enough rotations the “as-rigid-as-possible” technique generates high-quality interpolations. However, large rotations can lead to inconsistencies that cause artifacts such as those shown here (right). Our technique yields consistent rotations, resulting in the expected rigid interpolation (left).
