Re: [osg-users] Visitor concept. No finalize?

This would require the user to be aware of the fact that the Visitor has not finished its work after dtor is called. This is even more user unfriendly in my point of view. Sam -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=35988#35988

Re: [osg-users] Visitor concept. No finalize?

Hi Robert, the second half of my post is about the second option you was talking about. The apply only gathers the nodes in question and does nothing else then there is another method that performs the removal from parent. But the issue with that is, that if I do not call this method, no removal

Re: [osg-users] Visitor concept. No finalize?

Hi Robert, I am aware of the possibility to define my own methods in the visitor but the point I was trying to explain is, that if I apply a visitor on a scene I would except that this visitor has finished its work after calling the node-accept(myVisitor) If I have a RemoveXVisitor and I as

Re: [osg-users] Visitor concept. No finalize?

Hi Robert, I suppose I expect that because let's say a RemoveGroupsVisitor should remove Groups from a given graph, when I apply this visitor to a scene by Code: RemoveGroupsVisitor r; scene-accept(r); I personally would expect that now the groups are removed, which they are not by the

Re: [osg-users] Visitor concept. No finalize?

Hi, that is exactly the point. My RemoveXVisitor SHOULD remove nodes but since it is not possible to do that in apply and there is no finalize method that gets automatically called after accept has finished, it is only possible to remove nodes by providing a custom member which the user must

[osg-users] Visitor concept. No finalize?

Hi, I was writing a Visitor that performed an extraction of certain elements from a scenegraph. My first try was to remove the nodes in question from their parents directly in the apply method which lead to some exceptions. So what am I doing wrong? I mean I would except some finalize method

[osg-users] Swapping ref_ptr

Hi, I am in a situation where I receive a osg::ref_ptrGroup to which I should add a Transform Node (or basically prepend it) Usually the group I receive is in a hierarchy of nodes, so I was thinking about getting parents of this group, removing this group as a child and add the Transform

Re: [osg-users] Swapping ref_ptr

Hi, passing a ref_ptr by reference. This sounds somehow strange to me. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=29517#29517 ___ osg-users mailing list osg-users@lists.openscenegraph.org

[osg-users] gDebugger see memory leaks in 14 lines of set up code when FBOs are used

Hi, I spent the whole day chasing a weird memory leak on my GPU. The following code is part of a (not working well) FBO render solution. Code: #include osg/CameraNode #include osgViewer/ViewerEventHandlers void foo() { osg::ref_ptrosg::Camera c = new osg::Camera();
