Hey all,
I'm using osg 2.9.8 and trying to do intersection tests in a thread. The code
is real straightforwards and works well when not threaded:
Code:
osg::ref_ptr<osgUtil::LineSegmentIntersector> intersector = new
osgUtil::LineSegmentIntersector(start, end);
osgUtil::IntersectionVisitor visitor(intersector);
visitor.setLODSelectionMode(osgUtil::IntersectionVisitor::LODSelectionMode::USE_HIGHEST_LEVEL_OF_DETAIL
);
osgEarthNode->accept(visitor);
if(intersector->containsIntersections())
{
osgUtil::LineSegmentIntersector::Intersections::const_iterator firstHit
= intersector->getIntersections().begin();
worldIntersectionPosition = firstHit->getWorldIntersectPoint();
worldIntersectionNormal = firstHit->getWorldIntersectNormal();
return true;
}
Is this a known issue?
