Hi folks,
 
For those of you who couldn't be at SVG Open, or who missed Zack Rusin's talk, among the many interesting things he discussed were "diffusion curves" -- flexible gradient fills that are (according to proponents) better than mesh gradients for filling paths with smoother transitional textures. I didn't know about these but had been working on an alternative that I'll hope to describe in another message. After hearing him talk so enthusiastically about them, I had to look and found this really cool demo done at this year's Siggraph by folks at INRIA, Adobe and other places.

I know INRIA has a big interest in this sort of thing (useful for systems of PDE's) having tried unsuccessfully last year to help them use SVG in this direction . My own idea for expanding gradients that I was talking about to some of you is, I think, much lighter weight, than what these folks seem to be doing, though I haven't read the paper at all. Maybe both approaches are worth thinking about so I'll go ahead and write up the thing I was talking about since it is a very easy alternative, computationally and conceptually.
 
The interface they demonstrate is quite compelling and I have a feeling from the video that it is a much more analytic approach engineered with an eye to extensibility, speed, etc. It is well worth looking at the above and thanks to Zack for bringing it to our attention! (does anyone have an email for him?).
 
David
