Rendering of 3D features using OSM2World and Blender3D

OpenStreetMap has currently a growing amount of building data, that have
heights and further details to do 3D processing, which is already done by some
minor projects:
http://wiki.openstreetmap.org/wiki/3D_Development

Sadly for consumers, most Viewers are work in progress and need powerfull
hardware, or are "just" static isometric map renderings, that don't cover the
whole planet.
But the consumers might want to have a full interactive and global 3D
representation, with buildings (and maybe city furnitures and nature), as what
Google Earth already offers (but of course a free tool and with free data).

To enable Marble users this kind of experience, I suggest two approaches:
1. Enabling the OSM vector parser to make use of 3D map features
2. Embedding the W3DS offered by www.osm-3d.org to pull online vector tiles

>From my POV, I suggest the 2. for several reasons:
- parsing 3D features is not easy and needs powerfull hardware
- using a service would have to good splitup in frontend/backend

But anyway, there needs be found a solution, on how the service offer enough
performance for the whole marble comunity and of course how the 3D vector tiles
can be displayed in Marble
