Resumen
A common variant of caricature relies on exaggerating characteristics of a shape that differs from a
reference template, usually the distinctive traits of a human portrait. This work introduces a caricature
tool that interactively emphasizes the differences between two three-dimensional meshes. They are
represented in the manifold harmonic basis of the shape to be caricatured, providing intrinsic controls
on the deformation and its scales. It further provides a smooth localization scheme for the deformation.
This lets the user edit the caricature part by part, combining different settings and models of
exaggeration, all expressed in terms of harmonic filter. This formulation also allows for interactivity,
rendering the resulting 3d shape in real time.
