Philippe takes a forum thread about “texture wrapping” and turns it into a tutorial. During the process he got a real nice tree bark.
With texture wrapping you can give a flat texture the look of being on the surface of a 3-dimensional body. This is the domain of Raytracers and 3D programs like Blender. But for that you need a mathematical model of the body in question. This is not available in photographies.

And if you want to take a look at researcher way to do that stuff, here is an interesting video http://graphics.cs.cmu.edu/projects/nrt/NRTAM.mp4 from http://graphics.cs.cmu.edu/projects/nrt
really nice show!
Incredible!
Thanks a lot, I was wondering about that.
I’ve been away a lot and haven’t been able to look at Meet the Gimp for ages, so now I have a lot of catching up to do. I just thought I’d mention that I still find that the files present themselves as MP3, though I can still work round it by downloading them and renaming them as MP4 files.

Great show, Philippe. The way one can play with textures in GIMP, is a whole new world to me. I am very much interested in that and I am looking forward to see more on this subject.
