== Conventions Used == | |||
The following lists some naming conventions, which you must follow when placing files into the directory structure, naming files etc. Some of these conventions are hard-coded in osm2city related programs. | |||
Regions (actually here synonym for country): | |||
* Use the ISO 3166 alpha 2 country codes. E.g. US for USA, DE for Germany, GB for United Kingdom (do not use UK). | |||
* Only top-level directories should be called with 2-letter country codes. | |||
* If you do not know the country, use a good guess. | |||
* Currently there is no mechanism to distinguish textures within a country - e.g. in Switzerland low-lands vs. Italian speaking mountains. | |||
File naming: | |||
* A suffix "_LM" denotes a lightmap for a texture (needs to have an otherwise exact same name) | |||
* A suffix "_MA" can be used for a mask pre-processing a lightmap. The file is not used in the texture atlas, but can be handy to keep. | |||
* A prefix of "roof_" is used for textures of roofs. | |||
Texture registrations: | |||
* All roofs shall be registered in a file with prefix "roofs_" and having the file type ".py". You must have very good reasons not to just register in the default file "roofs_default.py" in the top level directory. | |||
* Textures for facades can be registered in different files, but it is recommended to use fewer rather than many files - maybe just one file per region within the region specific directory. | |||

* | * Copy texture and lightmap to tex.src/ - in most cases into a region specific sub-directory. | ||
* | * Add the snippet generated by texGU.py and enhanced as described above (e.g. "facade_24x19m.py") to a *.py file in tex.src/ | ||
* If you're adding a roof, name your texture "roof_something.png" and append it by default to tex.src/roofs_default.py. | |||
