Re: [osg-users] update operations vs. update traversals
Hi Robert, thank you for the explanation. My use case is actually installing new nodes into the scene graph (dynamically generated ImageStreams playing videos as needed). I will be using update operations, but not necessarily using separate threads for these. Although it would be interesting to see if the video decoding could be shifted entirely to a separate thread - if the FFMPEG plugin doesn't already do that).

I was wondering if this method of updating the scene graph has any advantages over the classic methods of installing update callbacks, or updating things during the update traversal. The only two OSG examples making use of this feature are the osgtext example and the osgthreadedterrain examples. Internally within OSG the function isn't used anywhere, it seems. The osg::OperationQueue that manages the update operations is a thread safe container that allows you to pass Operations from other threads to the viewer so that viewer can call then during the update traversal. Merging data built by a background thread is a good example of how one might use this facility. You can potentially do something similar with an update callback but it'd need to manage the thread safety etc. As conceptual note, scene graph Callbacks are really to do with the scene itself, such as animating an object, rather than viewer level operations.

Depending on how much work you do in creating the new nodes it might be appropriate to use a back ground thread and pass the merge via an custom osg::Operation, but if it's just quads then it's like they you won't need a separate database thread as it'll be so cheap to create the objects in the main thread - all could be done inside the osg::Operation. I will be using update operations, but not necessarily using separate threads for these.

All the video related plugins run a separate thread(s) for doing the reading of the video.

[osg-users] MSAA in GraphicsWindowEmbedded
Hi everyone, I am using OSG in combination with Equalizer. So I'm setting up my Viewers via Viewer::setUpViewerAsEmbeddedInWindow(). Now I want to use MSAA.

You need to be using GraphicsWindowEmbedded, and your call to eglGetDisplay() should use EGL_DEFAULT_DISPLAY .
