Re: [osg-users] [ANN] OpenMW: Announcing switch to OSG
Looking forward to seeing your progress :) OpenMW was the coolest project created with Ogre in my opinion, and could well be the coolest created with OSG as well. It definitely sounds like it is a better match for your project than Ogre was, even the new version 2. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=62884#62884 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] referenced memory management across dlls/exe (Windows only)
Thanks Sergey. I found that too. The problem was that the a core lib was keeping a ref_ptr of an Object allocated by a plugin from a dll. Then on clean I got this problem. I solved it by changing the ref_ptr to observer_ptr in the core lib. So I am good now. But BIG thanks for helping me. Ulrich, thanks too. Nick p.s.

Re: [osg-users] Custom CompositeViewer Events
Hi John, To add custom event handling there isn't normally a need to subclass from CompositeViewer and Geode. In snv/trunk and the OSG-3.3.x dev series there is now an osgGA::Event base class that you can subclass from. You can add your own events then inject them in the the View's EventQueue, these events will then be passed on to the EventHandlers attached to the View(er) and Event callbacks placed in the scene graph. In the EventHandler/Calback you get the pointer to the Event base class and then cast it to your custom type. In OSG-3.2 and before you can subclass from osgGA::GUIEventAdapter. It's not quite as clean as the new osgGA::Event but should work just fine. Robert. On 28 February 2015 at 17:09, John Farrier john.farr...@gmail.com wrote: Hi, I have a program which is using a custom viewer derived from osgViewer::View. In this custom view's scene may be some custom types derived from osg::Geode. I'll call these MyView and MyGeode for the sake of the post. MyView's are put inside a osgViewer::CompositeViewer. All this works great. Now, I want to send custom events to MyView and MyGeode. My original hope was that I could just register a handler on MyView and MyGeode and do something like compositeViewer-accept(new MyEvent), but it doesn't seem that easy. I ended up creating a MyCompositeViewer that has an accept function on it that takes MyOsgGaEventVisitor and then create a MyGUIEventHandler which attempts to dynamic_cast osgGA::GUIEventAdapter to MyEventAdapter. MyGUIEventHandler is created with a pointer to its owning MyView and then can make calls into MyView based on the event. I haven't started working on getting the event into MyView's scene and onto MyGeode's yet because this design is challenging my sanity. This approach works, but seems like a mess. Before I get too far down this rabbit hole, what is the RIGHT way to get a custom event sent from a top-level CompositeViewer to its subordinate views and then onto the view's scene nodes? The examples in OSG seem to address parts of this problem, but I can't see a solution to the entire scope of the problem. Another way to phrase the question might be: How do I create a custom OSG-wide event that can be responded to by all osgViewer::View's and osg::Geode's alike? Thank you!

[osg-users] Find out if a node is dirty
Hi, I wonder if there is a way to find out if a scene graph node was updated recently. Specifically, what I'd like to know is if geometry was updated, or if a transform node has changed. I am using the scene graph from within an application plugin, i.e. I cannot set things like callbacks or attach user data, because I may in general not assume that the creator of the scene graph hasn't already done so. My plugin is merely a consumer of the scene graph. I've seen the dirtyDisplayList functionality, which however seems not to store any information useful to me. Any help is appreciated! Thank you!

[osg-users] Keyboard Manipulator and TrackballManipulator not playing nicely with each other.
Hi, I am trying to implement a KyeboardManipulator for translating, scaling and rotating 3D models via keyboard, similar to the TrackballManipulator. I am surprised that osg does not have this already. I wrote a keyboard manipulator class to at least zoom in and zoom out and translate the model. However I am having a hard time getting it to work with the Trackball Manipulator. Once I update the view matrix via keyboard, the TrackballManipulator does not resume from there. Obviously, unless told, it has no way of figuring this out by itself. So I tried to find some function which will cause the TrackballManipulator to update its state based upon the current view matrix. But I couldn't find any function which does this. setByMatrix does not seem to work the way I expected. The TrackballManipulator goes bonkers once I update model via keyboard and use setByMatrix. It does not allow the model to be rotated properly afterwards. Somehow the rotation axis changes and a small mouse movement causes it to pan the model rather than rotate it. Once I manipulate model via keyboard, what steps are needed for me to update the TrackballManipulator to continue from there instead of resetting the model position.? ... Thank you!

If I clean these pointers from the originated dll, it works ok, otherwise not. Any clue? You end up with different instances of the runtime library, each with its own heap management. You allocate the object on the heap of one DLL and free it onto the heap of the other - bang. Sorry, I don't know what the corresponding flag might be on mingw.
