One thing I would really like to see added in the 3D support before
3.0 release would be to add a "save as image" option. Currently it's
great to be able to play with data in 3d, but adding the option to
export the camera view to an image file would take take the 3D support
from being purely "exploratory" to instead becoming a "visualisation"

Totally agree with all the above. Personally, I'd love to see some
group of users start to take charge of extending QGIS' BIM
functionality/integration abilities. Is this something you'd (or any
other readers) be interested in doing? I'd suggest starting with a
thread on the user list, and start collating documents (e.g. via
google drive) for requirements/desires to make QGIS a first class
player in the BIM world.

Yes, it uses the Qt 3D module, not OSG. There's another thread on this
list from last week discussing what future the globe plugin has.
