Re: [osg-users] Discussion: metadata readerwriters output

Hi Bob, Ulrich is right: you could move your data as a metadata. However I guess that we should not break existing code. (De)Serializers should NEVER overwrite existing userData, they should only be allowed to add metadata it userData points to a meta container. So if you already use userData,

Re: [osg-users] Discussion: metadata readerwriters output

I concur, in order to avoid disrupting existing users, metadata should only be read/written to if UserData is empty or already contains a metadata object. Possibly we could have an abstract metadata or de/serializable interface so that users could retroactively support their existing UserData

[osg-users] Why does Draw skip frame number as reported from FrameStamp::getFrameNumber()?

I'm resending this with a new Subject: line. Worried that it was a little too cryptic. I'm trying to understand how the threading works in OSG when DrawThreadPerContext with respect to which process is on which frame at which time. It appears to me that the draw frame is skipping values in

Hi Anna, I've looked into the NodeTrackerManipulator::validateNodePath() implementation and can confirm that the itr != _trackNodePath.begin() is an error. When reviewing the implementation I decided that the code would be better off using the new osg::ObserverNodePath rather than it's own local

Re: [osg-users] Why does Draw skip frame number as reported from FrameStamp::getFrameNumber()?

Hi Brad, I couldn't make sense of your original email and same with this one, I'm confused by the role of your map and would suspect that your method is the cause of the odd output. The way I'd check the current frame number is to simply have a draw callback directly output the frame number.

It was a bit hard to describe. Let me try to take one more crack at it. I have an object derived from an osg::Node for which I've implemented my own virtual void traverse(osg::NodeVisitor nv). Inside that traverse I keep track of the frame number as reported from the CullVisitor. In a

Re: [osg-users] Why does Draw skip frame number as reported from FrameStamp::getFrameNumber()?

Simplifying my example, my PostDrawCallback now simply prints the pointer value of *this (to determine that it's the same PostDrawCallback instance) and the frame number and I get the following (snipet): 0x2a9a400:896 0x2a9a400:896 0x2a9a400:898 0x2a9a400:899 0x2a9a400:899 0x2a9a400:901

Re: [osg-users] Segfault with inherited osg::Drawable

Hi Mathias, This sounds rather like you've got a dangling pointer somewhere in your app. The OSG uses reference counting for all the internal scene graph objects which is specifically to avoid dangling pointers and to leverage this safely you are best to use ref_ptr to all OSG objects. Lots has
