David,



You just need to disable GL_DEPTH_TEST for
the desired object(s).



e.g.:



myNode->getOrCreateStateSet()->setMode(GL_DEPTH_TEST,
osg::StateAttribute::OFF);

hi


i would like to draw some objects without doing the zbuffer check, so it´s
always visible no matter if it´s something between the object and the
camera


i guess it has something to do with the stateset but i´m a little lost here
