Hello everyone,
I'm making PickHandler inherit from osgGA::GUIEnentHandler. This class implememt Pick function. In this Pick func., there are PolytopeIntersector. And I use it as follows osgUtil::PolytopeIntersector* pPicker = new osgUtil::PolytopeIntersector( osgUtil::Intersector::WINDOW, dX - dW, dY - dH, dX + dW, dY + dH ); Here, I wonder what is the difference between osgUtil::Intersector::WINDOW, VIEW, and so on. Jeongseok.
