This plugin uses light colors in an image to produce either horizontal 3-D or height 3-D extrusion.
Darker being lowest lighter being highest.Height is adjustable as well as other parameters.

Fun to play with.

Here is an example of my stop sign image i created yesterday.This kind of gives you a idea what this filter is capable of.

This would be really useful to me. Is there a 2.6 version?

You can try testing this one in Gimp-2.6, It should work.

If not i do have another version for Gimp-2.6.12 i believe somewhere on this website.

Excellent. It works fine - thank you.

Thanks Rod! Another very useful script working in Gimp 2.6.11 - I wanted a quick way of producing isometric game objects, this is just the trick. Can you give a quick outline of compiling the script? Is it straight forward?

Compiling in Windows is tricky but Partha lays it out real clear on his website.
You will need to compile Gimp so you have the gimptool-2.0

Once you have successfully compiled BABL, GEGL, and Gimp you should be able to compile just about any c plugin.
I do more compiling of c plug-ins than anything else. ...
Although i have compiled Gimp versions -2.6.12, 2.7, 2.7.5, and 2.8.

http://www.partha.com has all your environment setup needs, and will answer any of your compiling questions.

Once you have the environment setup its as simple as opening your Msys command window , cd to the c file directory, and typing ...
gimptool-2.0 --build file.c - you need Gimp compiled because you need the gimp h files, and the gimptool.

Compiling Gimp looks hairy! I'm not sure I'm ready for that and I'm looking to stick with 2.6.11 (only because 2.8 was totally unstable on my system when I tried it a couple of months back - have things improved?).

I was wondering if I could set up a tool chain for compiling plugins without compiling Gimp (probably same difference though it would most likely be capable of compiling Gimp). I got stuck trying to find a GTK+ 2.16.6 bundle though. I take it you compiled this plugin using library from GTK+ 2.24.10? The resulting plugin works fine with my 2.6 version of Gimp so I'm wondering could I do the same?

This is a pretty cool script. I have found that it is good for effectively rotating an already made height map image. The photo below shows what I started out with as a height map bear. And to the right of that is what it looks like after using the filter. And below is what the images look like after inverting the color to a white back ground and using the emboss filter followed by colorize.



I'm wondering where this script came from and are there any others like it?

The original author of the c plugin file is Kyoichiro Suda.

The website is here (no longer working) - http://sudakyo.hp.infoseek.co.jp/gimp/l ... ght_e.html
Another great plugin by this author is "Focus Blur"
I don't know of any others right off the bat.
I am pretty sure Sam has windows binaries compiled for Gimp-2.6.12 on the gimp registry somewhere.
Sam may know more about the author.



Yes i use all the latest dependencies. These can be found on Parthas website (links to them). I have heard compiling just c plugins is possible but i have never successfully accomplished this.Only after compiling Gimp was i able to do this on Windows.It just doesn't seem to work without a full Gimp version install with a path to the pkg config pc files added to the export PATH variable in the ect\profile file.

I also use mono

Then your fstab file would look like this -
