Automated export from OpenStreetMaps

[breznak]

This new feature should allow users to select area or cities in a map (OSM) and export them to OpenDS automatically.

This will use:

• export from OSM
• Blender to re-create 3D env (buildings,...) using simple, default skins.
• create an ODS model that can be loaded as a map

TODO:

• [x] select area in map GUI (OpenStreetMaps) and export it
• [x] render roads and some basic 3D structure (terrain, buildings, ...) in Blender
• [ ] load the j3o file automatically in our simulator (OpenDS) -- Blocker
  • [ ] file an issue at jMonkey project, see https://github.com/breznak/openDS/issues/1#issuecomment-195059529
  • [ ] alternatively, save the file to a default location and the user will do a basic ("Next, Next..") import

@JohnnyMarek what's the progress on this task?

[JohnnyMarek]

Load from OpenStreetMap to Blender is done automatically, still need to solve how to export to .j3o file without doing it manually so it can be used in OpenDS. Will update my progress when it's done.

[JohnnyMarek]

Didn't find any solution not even on original jMonkey Forums, it looks like there is no way how to do this step without jMonkeyEngine software (because Asset Manager from here is required when new .j3o file is made), j3o is serialized file and from what i understood even jMonkey developers say it is not possible do this automatically at this moment. Will try to find different approach after all other tasks are solved.

Working code implemented in #38 using OSM2World project; Still, manual use of Blender and jMonkeySDK is needed - we wish to automate the process. Another discovered issue is #11
