Hi J-S I removed the camera manipulators on the slave machines, and it instantly worked.
But I should explain my project in more detail, maybe you can give me some feedback :) I'm working on a cluster solution for osgVisual (www.osgVisual.org). I use ENet as UDP implementation (better than my own first prototype) I use the osg serializer to transport data (in my case a special transport container) to the slave rendering machines. At the master machines, which receives the external data and process it to display, I use several kinds of camera manipulator ( object attached, objecet tracker , free 3D mouse, 3D mouse object tracker etc) I process the incoming data on the master on the prior to the event traversal. A camera manipulator calculates the camera position from this data, and during the event traversal I grab the view matrix and send it to the slave. on the slave machine, I receive the view matrix during the event matrix and set it on the viewer. After your information, I think the slave machine will render the received view matrix at the same frame, because I set the viewmatrix prior to the update- and renderingTraversal. But How can I improve the situation on the master machine? The external data is processed at the beginning of each frame. Then I call the event-, update- and renderingTraversal. You said, the view matrix based on the camera manipulator is calculated during the cull traversal, so the viewmatrix I send during the camera->eventCallback is the viewmatrix of the last frame. Do you have any idea how to use camera manipulators to control the camera position on the master machine, but still to calculate the current view matrix as early as possible to send it to the slaves as early as possible? I would appreachiate your feedback very much :) Cheers, Torben ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=30245#30245 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
