Thanks.
I have downloaded the osgGIS project to get the solution.

Take a look at osgGIS. It is a toolkit for accessing GIS vector data and
visualizing it in OSG. There are a couple options for draping geometry to the
terrain -- you can clamp geometry to an existing terrain (works for points and
lines), or you can use osgGIS to generate a scene graph and then use the
osgSim::OverlayNode to project that on to a terrain (for polygonal data).
The main wiki is http://osggis.org and there is a support forum/mailing-list at
http://osggis.org/forums. -gw

Hi EveyOne!
My Application needs to render vector like line or polygon with different color
(transparent effect) on the surface the terrain. And the users can select to
load or unload the vector layer.
I have no idea about this. hope your suggest.
Thanks.
