HI Nilton,
I think you might be misunderstanding the use of the word traverse in
the context of scene graph traversal. When the NodeVisitor traverse
the scene graph they are consider the internal data structure links
between parent nodes and their children. In the case of the cull

Hi everybody,
I am not sure that the class "TRAVERSE" could control the transpass of the
building walls.
I would like not to pass by the walls while navigating with the camera.
My source code is:
nodePath[c]->setUpdateCallback( new SetTransverse() );
...
class SetTransverse : public osg::No
Sorry for the mass, I'm really new into OSG and I just can't find some basic

We (www.jct.ac.il) are doing some 3D non-linear implicit function research

my camera to the closest polygon/vertex and then run some math iss
Hi Oren,
This is a topic that has been discussed in osg-users before so please

You started the thread before, and got and answer that looked for

Hello all,
how do I traverse the list of geometry created during the cull traversal??
thank you

Hi Valery,
Geode's are meant to be leaf nodes, so are no intended to have
children other than drawables - which is why traverse() isn't
appropriate in this case.
If you do want to customize behaviour then could implement override
the Geode::accept() method, this is called before the
NodeVisitor::
Thanks a lot for explanation to you and Артём, but my class is derived
from Geode, therefore osgUtil::UpdateVisitor::apply(Geode&) calls
handle_geode_callbacks(osg::Geode& geode), which doesn't call traverse
anyway:
// should we traverse just in case a subclass of Geode adds children??
Won't for no
Opps...

I'm meant to write osg::Sequence, rather than Switch, so you'll want to look
at src/osg/Sequence.cpp.

HI Valary,
The update and event traversals both have use a mechanism that stops
traversal when no children of a node contain
any nodes that requiring traversing. This feature is key to maintain
good performance on very large databases, without
it the update/event traversals would take dozens of

Hi all.
I have a question why Node::traverse(NodeVisitor&) doesn't called with
NodeVisitor of type UPDATE_VISITOR?
I have a class derived from Geode and I remoulded function
traverse(NodeVisitor&) for some update operations:
void MyClass::traverse(osg::NodeVisitor& nv)
{
if (nv.getVisitor
