I found some interesting old Scheme code on the internet for doing 3D extrusion and have brought it up to date. The code was written in German by Frans Rijven and I've translated, debugged, documented and enhanced it to create a pretty nice 3D Extrusion script. The script uses Bump Mapping and GIMP's 2D Transform code for the extrusion.

It currently extrudes the image in a selected layer. In the next release, I'll add support for extruding an arbitrary selection within a layer.

The script can be downloaded from GIMP Scripts here.

The script is located under Filters/Render/3D Extrusion...

It works with GIMP 2.6.x & GIMP 2.8.x. Please feel free to post any comments, suggestions or questions. I hope you find it useful.

I love this filter, thank you for sharing Tux

Cool one, Molly. I like the rainbow of colors you got on the extrusion!

Thanks, I stroked it with my noise pattern at 6 pixels. On the text I filled it with the bling bubbles patterns.

For the b/w images it would be great to have as an option the extrusion based on image's height(depth) map.
Although, without it I get an interesting effect too.

Kite - that's an interesting effect.

I'm not sure I understand exactly what you're looking for K1. I plan on rewriting this script using techniques I'm developing in the Logo Toolbox script.

If you can provide some manual steps, it would help me understand what you're getting at and I can probably incorporate it into the rewrite.

Thanks!

I will explain, just need some extra time to think it over and make examples with images.
It's only in my head for now. Could be an interesting effect or total garbage.

My only question is how did you find this? :lol

I'm with Rod on this one. How do you locate the script in gimp once you've downloaded it?

If you download the script from GIMP Scripts, you can click details to see the menu location of the script.

3D Extrusion Release V2.0 has been rewritten from the ground up.

This script extrudes the image or selection in a given layer. Supports bump mapping & extrusion via 2D drawable transform.

Extrude An Arbitrary Selection Within A Layer
All Relevant Bump Map Options Now User Configurable
Option To Add End Cap
Option To Create Pattern Overlay
Option To Merge Visible Layers
Compatible With GIMP 2.6.x & GIMP 2.8.x

Extruded By Selection

Download the update from GIMP Scripts.

Future releases will include Layer Group support and smart re-sizing, but as it stands now, you'll need to ensure your image canvas has room for the extrusion.

What's "End Cap"?

I asked the same question Carlos. It is the top layer after you run the script that you can use to make more changes.
