I create a line on the terrain using overlayNode, all looks fine. Then, I add a EphemerisModel to the scene to create some environment effect.
After that, rotate camera is fine, but when I move camera(w a s d), the line I created moves on the terrain surface! confusing, ~ @_@ ~ scene graph is like: root / \ (line)overlay EphemerisModel | terrain I attached a viceo clip to present my problem: a overlayNode red line on terrain -> rotate camera(fine) -> move camera(ouch~) In the video, you can notice a blue object in center of screen, under the terrain, which comes with EphemerisModel, I don't know what it is, but it behaves the same as my red line when I change camera ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=46760#46760 Attachments: http://forum.openscenegraph.org//files/videoclip_357.rar _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
