[osg-users] different materials for a geometry and highlight

[Gianni Ambrosio]

Code:
osg::Geometry* buildGeometry() {
       osg::Geometry* geometry = new osg::Geometry;
       geometry->setVertexArray(buildVertices());
       geometry->setColorArray(buildColors(), osg::Array::BIND_PER_PRIMITIVE_SET);

       std::vector<osg::DrawElementsUInt*> elements = buildElements();
       for (std::vector<osg::DrawElementsUInt*>::iterator i = elements.begin(); i != elements.end(); ++i) {
         geometry->addPrimitiveSet(*i);
       }

       return geometry;
}



When I pick a triangle, is there a way from the information stored into a osgUtil::LineSegmentIntersector::Intersection to get the related primitive set?

Regards,
Gianni
