We use a Globe with relief generated by SRTM and visualized with Unity3D (as Google Earth ...).
We are now looking to add 3D buildings.
I have seen many examples on the web using CityEngine and OpenStreetMap datas.

I wonder what is the best way to proceed :
    Importing OSM and SRTM into Unity3D
Or Importing OSM ans SRTM into a FileGeoDatabse via  ArcGIS Desktop then Importing the FileGeodatabse ino cityEngine.

I saw that there is some trouble using WGS84 (no projection) into city Engine 2013 from a GeoDatabase.
Then I need to use an UTM projection.

I wonder if I could reproject the 3d Building in WGS84 once generated. (via ArcGIS desktop I suppose)

I wonder also if there could be some issue importing the building on a globe. Because all sample I saw from cityEngine was on a local coordinate system.

Best regards.
