None that I 'm aware of. You can do gradient meshes manually though, but I assume you are referring to that screenshot of Inkscape 0.45 anyway… ;-)

I've been looking at that gradient mesh picture and trying to replicate the manual steps. After half an hour of experiments, I'm not sure exactly how to proceed.

Do you start with the four sides of the beziergon as separate path objects? Then what? Any help in the form onf concrete steps would be appreciated.

the file 'gradient-mesh-experimental.svgz' is distributed with Inkscape in the directory 'share/inkscape/examples' (the location of that depends on your OS - for win32 you have to look for yourself, on linux it's in '/usr/share/inkscape/examples' AFAIK, on OS X it's inside the application bundle 'Contents/Resources/examples'). Take a look at it if it helps to answer your questions...

Thanks! I'll look at that when I have some more time.

oops - sorry Kjohrf, totally missed your name when replying ;-) You are on win32 AFAIR, the file must in the installation folder somewhere, near the folder with the official extensions...

Thanks. Yeah, it's in .../Inkscape/share/examples. But I didn't find that much more helpful for getting from one step to the next.

What is an svgz file (as opposed to svg)?

Kjohrf wrote:What is an svgz file (as opposed to svg)?

It is an SVG file compressed with 'gzip'. Don't know for sure how it is handled on win32 - try renaming one into 'file_name.svg.gz', IIRC WinZip can open and 'gunzip' it and you get the plain text SVG file. Isn't *.svgz associated with Inkscape on Windows? Else the installer definitely needs some improvements for the next version ;-)

I'll see if I can find other resources for this topic, but keep in mind - that example file illustrates a concept how Inkscape internally could implement gradient meshes, it is not meant as step-by-step instructions for everyday-easy-to-use simulated gradient meshes, at least that's how I understand it ;-)

Seems to open up directly via Inkscape. Not sure how, but I'm happy.

Thanks. I'll play with it some more when I have some time in a couple weeks to see if I can make more progress understanding how one would do it manually. Appreciate your help!

i know that gradient mesh is a great tool for illustrator, but personally i don't think inkscape needs it. Try using just paths - blur - gradients - opacity, play with them and build a piece just like a puzzle. Sure it's a long work

Rather than gradient mesh I'd like to see Inkscape try to adopt the diffusion curve method that was posted a while back.

I have no idea. I know that application used in the video was not an open source project. I'm not a programmer so I don't know the mathematics or coding that would be necessary to make it work in inkscape. would be very cool though.

Wow. Very cool.

That is nice, but not a part of the SVG spec, which is what inkscape is limited to.

(There has been some discussion on adding diffusion curves to the SVG spec, so if that happens, I would expect it to be implemented.)

Does SVG support gradient mesh? Hopefully they'll add diffusion curves to the svg specs.

It could be implemented as a Inkscape specific tool maybe and get converted on save to SVG?

Not yet.

Inkscape would have to implement it as a grid of blurred polygons, each with its own gradient.

The January SVG working group teleconference http://www.w3.org/2009/01/22-svg-minutes.html had some discussion on it.
