I absolutely love the galvanized effect of the Felimage filter you recommended so I had to make something just to play around. I think this is the method of choice although I would like to know how to acheive the same result from scratch. If you know how to look at that thing and figure out the steps it uses I would be very grateful.

The xcf is over 15 MB and zipped it is still 5.53 MB so I can't attach it here.

This is what I made out of it.

very cool looking. that effect really has me going woah don't want to be there

You can get some really far out results with the settings.

That looks good, Draconian.

They use a special type of noise for the galvanized effect. I don't know you could do the same thing with the standard noise generators. Have you explored GIMPressionist? I'm not a filter effects guy, but that filter does seem to have a lot of possibilities.

I really like the Felimage noise generator. I even wrote a script so I could do difference noise with it just like the standard noise generator. About the only thing it doesn't have is plasma noise. Or if it does it is very well hidden and I haven't found it yet.

I hope someone compiles it for 64-bit.

That is the main thing that is keeping me from switching to the 64-bit version of GIMP.

Wow, that is a cool effect Rod.

Thanks BKH, Hopefully we'll get the filter guy to weigh in here and give us some pointers. I know Lyle has been playing around with Gimpressionist.

For a starting point you can use my multifill script to get an effect similar to the galvanized metal.

First render a voronoi pattern and threshold it to have black lines on a white field.

Then run the multifill script choosing the "Gradient with random direction" button and set the ignore and flag areas down to 0. IT takes a long time to run with small cells like I used here:

Seems to need more RGB speckles, and wind streak noise.

I looked under Filters>Render and looked unter GMIC>Patterns and I can find nothing that says "Voronoi" How do you render this pattern. Looks pretty much like the Mosaic pattern.

You are correct. Voronoi is a plugins (Japanese page, English plugin): http://www.geocities.jp/gimproject/plug ... ronoi.html

Am I correct in assuming this gets installed in Gimp-2.0\lib\gimp\2.0\plug-ins?

Or more preferably your user plugin folder (which depends on OS)...

Great! I have it installed and it comes up ok but no matter what I do I keep getting the square gradient pattern. Applying threshold just gives me little black squares. what settings did you use with the Vironoi render?

I couldn't get the Voronoi render to work right so I just used Mosaic to get a pattern. I ran the mulifill script and it did take a while and it seemd to work ok, but when it finished I got this error. Any clues?

That errors seems to have started popping up with gimp 2.6.11

Another script I wrote also does that...It doesn't seem to effect operation though.

-Rob A>

I wonder if it has anything to do with the newest Gimp-2.6.12 update?

I can live with that. What were teh settings you used to make the vironoi render?

Rod - I'm still using 2.6.11, How can it be related to 2.6.12 unless it was written for that version.
