So far so good. The culling works as expected. I can now define a custom active invisible area and the picking works with it. Unfortunately it did not quite tackle my problem with dragging.
The question have now: How do I manually intersect a ray with the x/y-plane of geode? The problem I have is that when I drag an object, the mouse pointer (in my case it is actually one of multiple touches) momentarily leaves it within one frame and the move handler that adjusts the new location is never called. My first approach was to increase the active area so that this does not happen but this leads to all kinds of problems and is not fully robust, conceptually speaking. Instead I would like to do the following: Objects get clicked on, I do normal picking. On mouse drag and up I do manual ray intersection with the entire x/y plane of the object that got the mouse down previously. This way the object never miss out on the drag/up. So how do I manually intersect a ray with the x/y-plane of geode? /stefanix ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=13953#13953 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
