GEGL is doing everything it can to do away with Adobe CC. This filter makes an extrusion effect with GEGL and even has the ability to change the lighting on the extrusion.
I hope everyone enjoys.

Very useful. Here it is with the help of pattern overlay in layer-fx.

Out of curiosity, did you write your filter with "Filters/Map/Recursive transform"?
viewtopic.php?f=11&t=18573&start=440#p269048
or here chapter 5) Extrusion toward center viewtopic.php?f=4&t=19547&start=20#p269000

No the filter is based on zoom motion blur, threshold alpha, screen of edge detection, emboss and lighting filters.

I could have made it where this filter doesn't require the behind blend mode but that would have taken a ton more work linking gegl refs and ids in C file. And it would not have the non-destructive ability of separating layers for those who prefer applying the effects on a layer below.

Windows 7 GIMP 2.8. I have GIMP 2.10 on another PC . Where is the code I need? How do I install? Do I need to put an extension or change extension after saving to the desk top using note pad? If someone could help.... Thank you.

HI gimpmannew. Looks like the filter has not been compiled for Windows. If MareroQ or Mahvin don't do it once I get home, I will compile it.

For GIMP 2.10:
Version for Gimp-2.10.32 Win 64 Bit attached.
Place the file in Gegl plugins in a directory: C:\Users\YourName\AppData\Local\gegl-0.4\plug-ins
If you're missing the plugin-ins folder, create one.

In menu Tools➤GEGL Operation➤

I don't know if this version will work for the 2.8 version.
For GIMP
For GIMP 2.10:
Version for Gimp-2.8Win 64 Bit attached.
Place the file in Gegl plugins in a directory: C:\Program File8\GIMP 2\lib\gegl-0.4

Yes, it rules with 3d text!

Thx for showing the settings for thinner text styles. :bigthup

I was having a very hard time with Garamond.

Here is a good one I made a few months ago with clay and extrusion.

Gegl:extrusion has been updated.This update made quality feature changes and allows extrusion to use GEGL:Bevel and enable and disable the edge detection of screen if the user doesn't want it.

It also has no hidden zzoperations. However it now requires using GEGL Bevel (which it ships with)

GEGL-extrusion works best with Gimp's 3d transform and my other bevel filters. If you have multiple copies of gegl:bevel it is perfectly fine. I have no plans on updating that filter as it could break tons of other things.

Enjoy!

Oh yeah I changed the default preset as well.

Thx contrast. Win64 dll attached. :bigthup

File removed.

I hope you compiled it correct. It requires bevel.

I did not add bevel. i removed the file. It worked fine for me just compiling extrusion but i guess i assumed everyone would already have the GEGL filter and would only need to update extrusion.
