Fig. 2

The smooth time-trajectory (dashed line) of a deforming 3D shape (cube). The object shape is represented by a single point (blue sphere) with coordinates relative to 3D basis shapes Ŝ1, Ŝ2, and Ŝ3 (not shown). As the shape deforms smoothly over time (t), its point representation describes a single, smooth 3D shape trajectory.
