HI Latha,

I can't work of what you are specifically trying to achieve and why,
this is important as knowing what problem you are trying to solve is
key to knowing what the best way to solve it is.

I say this as in general most application don't attempt to place very
small geometry elements like quads in their own separate subgraphs,
normally you'd just place them in all a single osg::Geometry.  Most
hardware can handle rendering of tens of millions of quads this way.
Have a look at the osgeometry example.

However, I can't say whether just a simple osg::Geometry is sufficient
as you've explain your solution rather than the actual problem.
Please explain what at a high level you are trying to render, i.e. a
road, a cable, etc.
