Hi,
thanks for all your replies;
use overlaynode,but the projected texture is not right,
any ideas?thanks!!

yellow lines-profile of geometry
Code:
geometry-addPrimitiveSet(new
osg::DrawArrays(osg::PrimitiveSet::POLYGON,0,v-size())) ;
geode-addChild(geometry);

Well, the example you showed is using texturing. I suspect if that's the
effect you
want, you'll
Hi Jason,
Last time I checked (half a year ago), osggis did no create a curved
polygon when creating a filled polygon for e.g. Russia. Since no
sampling points are created inside the polygon the tessellated triangles
goes straight from one edge to the other thought the ground.
It would be
No - osggis does not drape polygon geometries.

Hi Lipan,
You could look into using projected textures with the osgSim::OverlayNode or

recommend looking at osggis at http://www.osggis.org.

or a surface.
my issue is:
how to display the profile line to be a enclosed area, not lines.
