Abstract

- We reinterpret optical anamorphosis in a CAGD setting, as a rational FFD.
- The key idea is to use homogeneous coordinates with center at the viewpoint O.
- The control points of the deformation tool move along radial directions through O.
- With a linear Bézier tetrahedron as tool, the FFD yields a perspective collineation.
- In general, NURBS transform to NURBS of higher degree via rational composition.
