Hello,

We had discussed by email quite a long time ago about a library we were working on that implements Biharmonic Diffusion Curves. We eventually released a first version a few weeks ago, as part of our Patate Library : http://patate.gforge.inria.fr/html/vitelotte_user_manual_page.html

It implements the paper "A vectorial solver for free-form vector gradients http://dl.acm.org/citation.cfm?doid=2366145.2366192" (I've put my co-authors in CC). Starting from a mesh with constrained curves or points, it provides routines for harmonic and biharmonic diffusion using FEM.

Do not hesitate to give us feedback on the library module ! In particular, we wonder how it could fit in (or be converted to) the SVG format. A new version of the library with a few new features (color spaces, Bezier curves) should be out during the summer.

Best regards, Pascal Barla.
