Hi Bhanu,
> Hi,
> I am drawing nearly 4000 Quads.How can i reduce number of triangles in geometry. I tried with osgUtil::simplifier but it takes more time to load.Is there any other ways in osg.
4000 isn't exactly many. If each quad is a separate drawable however it 
could induce some performance penalties.

1. use the osgUtil::Optimizer (to convert your quads to triangles and 
depending on their structure to on vertex array). Try ALL_OPTIMIZATIONS

2. If you need to simplify you can store the result and use it from then 

Can you elaborate on the structure of your scene?
