Texture Library

Isn’t there a final option 5, which is to take a photo of the building and warp/fit it to the building model (as seen in Sketchup). I guess this is doable for the most important buildings, then we default to 3 then 4 then 2 then 1.

Hi Oliver, could You explain it again with other words?

Under Your 5 I understood 3

Sorry for my english :3
I think that the multitexture should be described by a formulas containing a placement algorithm and an occurrence frequency of each subtexture.
Also, subtextures can have an alpha channel for soft mixing with background subtexture or just for adding individual details like as air-conditioners and graffities. :smiley:

Of course Hind.
One thing more:
I still think about composite textures. Let me a little time, I describe the idea detailed and email it to You and other interested people.

I wrote the page:
http://wiki.openstreetmap.org/wiki/Seamless_Textures

I hope sombody can help to translate it into enlish. Hind, Could Yo translate it into russian and put Your input? I mean, You´re verya professional with texture making. Maybe you have some comments, references? Please feel free to add information to this page.

Under 3, you are still talking about “textures”, which could still be small images used to cover the walls of the building. These could be “picked” from a photo of the building, but we wouldn’t be using the whole photo to cover the face of the building. That is the difference I meant between 3 and 5. If/when this gets written up in the wiki, we should reorder these to go from simplest / most general to hardes / most specific.

You´re wright. We have to make difference between repeatable small textures (“seamless” textures and phototextures)
“phototexture” means: unique pict (prepared photo) without repeating per each facade.

If possible to You - lets´c come togeteher on the weekend to sketch up the specification/description for the wiki.

Absolutely cool: Freeware - http://www.mkupaj.skyraster.com/lens/application_d.html

It hepls to make lens distortion correction - important step in the process of seamless texture making.

No photoshop more necessary :stuck_out_tongue:

Because of many textures I did a new wiki subpages:
