some people are working on 3D OSM.
For this reason we need textures, because 3D models without textures looks VERY poor.
I modeled with my suff about 1600 historic models with textures.
Now I want to give this knowdledge to the community.
The first necessary step is the generation of texture library with very simple, generated, repeatable textures.
Here You can see the first results: http://wiki.openstreetmap.org/wiki/Texture_Library
I wrote also the page wit the instruction how to generate textures from own pictures:
I love really Italy and I visited this coutry many times. Unfortunately at this time i did no orthogonal pictures of typical walls, coluns, windows, roofs.
I know, the european architecture history doesn´t work without examples from Italy.
Can somebody of You shot such pictures and e-mail me? I convert the pictures into textures.
Example of country specific library: http://wiki.openstreetmap.org/wiki/Texture_Library_France
Best regards and thanks in advance!
