Hi Jan,
Your approach isn't safe. OSG is *not threadsafe*. Or, rather, it is
not threadsafe from arbitrary modifications. If you want to be safe,
the only time when modifications to the scene graph may happen is
before or after the frame() is invoked, not while frame() is running.

Hi Jan,
You can modify the scenegraph in the update traversal as well. Like I did
in the TerraPage (txp) loader. In the Cull traversall I collect info for
what is to be modified and then in the update traversal I update the
scenegraph safely.
Just a note

Hi Trajce,
I think Jan's answer [1] in the first mail mentions a similar
solution. Setting a flag (by using userdata of the drawable may be)
and updating the drawable in the osg::Drawable::UpdateCallback (of
course by checking the flag) MAY solve the problem. It seems that,
thrusting the Qt's
Hi Deniz,
yes I read Jan has mentioned this. Have a look in the osgdb_txp loader in
TXPNode::traverse() for inspiration if helps a bit

thrusting the Qt's Signal/Slot mechanism is not a good option as Jan
pointed.
I think the trouble is that you are expecting it to do something that it
isn't meant to do. Perhaps you have confused the
Hi All,
I have a problem with a short description, but with a long story.
My problem is simply the crash of my application while drawing dynamic
lines on screen.
Here comes the story;
I am using OpenSceneGraph (tried both 3.1.4 and 3.2.0) and Qt 4.x
with Visual Studio 2010.

Thanks for your answer. However, the ambiguous part for me is the
second paragraph of your answer. frame() is being called by the slot
which is connected to timeout() signal of QTimer. As far as I know,
frame() should not return before drawing the drawables with dynamic
