It's not on my TODO list. The OSG is community work, if you have the
itch then feel free to scratch it :-)
As a pointer of how to tackle it I would suggest looking at using a
PrimtiveFunctor/TriangleFunctor to stream out the geometry data from
the drawable. Have a look at other instances of these functors such
as in src/osgUtil/LineSegmentIntersector.cpp.
> Also, i know that the VRML format has some concept of primitive shapes. Do you think that the osg to wrl conversion would include the primitive ShapeDrawables? I would just try it, but unfortunately i did not build osg with vrml writing capabilities, and i won't have the opportunity to rebuild osg for a while.
I'm not up to speed of VRML or the author of the OSG's VRML plugin so
can't answer this specifically. In general I would say it should be
supportable but have to defer to others who know more about VRML/the
OSG's VRML plugin to comment.
