Hi Robert, thanks for your quick response. so here's what I'm doing: Code: if (viewer) { returnValue = ReactOnLCSPointClick( *viewer, i_eventAdapter.getX(), i_eventAdapter.getY()); } I tried as well with

Hi Jochen, There is too many unknowns about what you are doing for us to be provide any specific advice as to what is going wrong. It could be that your are passing in the mouse coords incorrectly. It could be that you are interpreting the intersections coordinates incorrectly. It could be

[osg-users] Model flickering on osgViewer

Hi, I compiled OpenSceneGraph 3.6.1 on a recently formatted Windows 10 laptop with up-to-date drivers. When I tried to run osgViewer with cow.osg, the model and screen started to 'flicker': [Image: https://preview.ibb.co/dbVWFT/photo.jpg ] (https://ibb.co/jeAnpo) but interestingly, when I

This looks like a driver bug, an reminds me of a problem in the nvidia driver having problems with display lists combined with depth_clamp. the osgviewer doesn't do the depthclamp, but the display lists might be a problem here. can you try: set OSG_OPTIMIZER=INDEX_MESH osgviewer cow.osg Laurens.
