Hello, Andrew, I remember you writing on this list some years ago, on the subject of alternatives to gradient fills.
I was able to find this message http://tech.groups.yahoo.com/group/svg-developers/message/54827 from you, but I remember an earlier message concerning the decomposition of gradients into piecewise linear or gradients segments. You compared it as I recall to being like representing curves as a series of small lines. I was working on some similar stuff with piecewise decompositions of richer gradients at the time. More complex gradients such as you illustrate and non-affine distortions such as allowed by the edit-transform-distort option in Photoshop are exactly the sorts of things that would make morphing from one image to another progress more naturally. The mesh gradient and the mesh distortion (such as allowed in both Illustrator and in Photoshop's "liquify" filter) seem to have similar underlying mathematics, and as Erik Dahlström pointed out recently, the topic is introduced a bit at Wikipedia: http://en.wikipedia.org/wiki/Texture_mapping . I gather what you are doing is a bit different than this however? I could not intuit much of the math from what you wrote on your web sites. Does anyone know if the techniques in use in Photoshop or Ilustrator are covered by extant patents? Thanks for sharing your work here, Andrew.

I do know (thanks to Mr. Ferraiolo), that there must be serious reasons to expand SVG specification (at least two progs, browsers mostly), but on the other hand implementation of advanced gradient fills promise so much... For example, RaveGrid is proclaimed as an extra quality raster to SVG converter. Well. May be someone wants to see, what is really qualitative conversion. Visit www.smartfills.com and download SVSViewer. I think, such techique could be used in Web with a great benefit too. Small vector files looking like nice raster ones, not like a cheap Japanese cartoon.
