Hi,

For those interested in Diffusion Curves, I recently finished my thesis
on Diffusion Curves. It can be downloaded here:
http://home.hccnet.nl/th.v.d.gronde/ThesisJvdGFinal2.pdf
(Initially it was also available from my university's site, but there
are some problems with the repository at the moment.)

Associated code can be found on LaunchPad:

In short: I found that it's not that easy to render diffusion curves
with high accuracy and looked at the cause of this, as well as possible
solutions. In particular, I implemented a renderer/solver based on a
different concept than the previously existing solvers, and this does
show some promise. Also, I found a way to make it easier to handle the
color discontinuities across diffusion curves (which are essential to
the usefulness of diffusion curves but can be tricky to handle correctly
in a solver), essentially by first removing them and then adding them
back in.

Comments, suggestions, questions, etc. appreciated.

BTW, most graphics were made using Inkscape (often saving to PDF+LaTeX).
