Harmonic Coordinates for Character Articulation

Pushkar Joshi, Mark Meyer, Tony D. DeRose, Brian Green, Tom Sanocki
August 2007

In this paper we consider the problem of creating and controlling volume deformations used to articulate characters for use in high-end applications such as computer generated feature films. We introduce a method we call harmonic coordinates that significantly improves upon existing volume deformation techniques. Our deformations are controlled using a topologically flexible structure, called a cage, ... [more]

Harmonic Coordinates

Tony D. DeRose, Mark Meyer
January 2006

Generalizations of barycentric coordinates in two and higher dimensions have been shown to have a number of applications in recent years, including finite element analysis, the definition of S-patches (n-sided generalizations of Bezier surfaces), free-form deformations, mesh parametrization, and interpolation. In this paper we present a new form of d ... [more]
