Allow choosing objects and LOD for export #10

Open Matthias84 opened 11 years ago

Matthias84 commented 11 years ago

Please add an possibility to select which objects should be exported and with what level of detail. For example, should buildings get very simple geometry (ground shape with height) or enriched with building_parts and so on...

Background: The usage of 3d models is quiet different. While static renderings would benefit from max details, interactive games or 3D printing need very limited geometric details (for speed and as only solid structures can be printed)

This is currently possible (to some extent - LOD is only available for very few object types) by writing a custom Java wrapper, using OSM2World as a library.

It would make sense to make configuration file options more powerful, exposing such functionality directly to users.

Sounds good :) But we should keep in mind, that even designers might be interested in 3D city models as input to their postprocessing processes. So for that usecase, I would recommend an GUI solution.

BTW would be cool if the objects could get grouped by it's general category, so the .OBJs are called buildings.obj, ways.obj, roads.obj, street_furnitures.obj, nature.obj ...

Would allow artists to load only what they like and to put all the things in single layers (think of fading effects etc....)
