Thin-Plate Spline Warp
A smooth deformation defined by moving a few control points while the rest bends like a metal sheet. Fred Bookstein popularized it in 1989 for shape analysis, and it is used for face morphing.

Spot it
- 01Smooth bending deformation
- 02Anchored control points
- 03No tearing or creases
Why it happens
Control point displacements are interpolated across the plane by a spline that minimizes bending energy, producing a smooth mapping that exactly honors each moved point.
