Are there advantages to modifying CullVisitor rather than overriding
traverse(), other than one dynamic_cast per frame per node? I think if
that's the only advantage, I'd personally prefer keeping all the code
related to the

Thanks, Bryan, I'll try and see if there's anything causing multiple

of the geometry or something.
Do you happen to know what the stats under the 'View' column refer to,
in
this case? E.g., StateSet, Group, Transform,

Group and other OSG Nodes declare operator= to be non-public so they
cannot be instantiated on the stack (which would easily lead to
problems
with OSG's smart pointers); you have to dynamically allocate them.
I should've checked

It compiles but gives a Segmentation Fault at startup.
Not a lot of information to go on, but here's a WAG:
count_width is counting

Hi,
It only gives a segfault if count_width is higher than 1. I've no idea
what
could be wrong...
Try looking at it in a debugger and compare count_width with the current
size of the vector.
For example, if count_width is 5,

How can I get group's geodes? Thanks.
The best way is to create a subclass of osg::NodeVisitor and override the
visit(osg::Geode) function. There are lots of examples that do this, such as
the osgcallback example.

OK, I think I have resolved the mystery. The VBO was being stalled by
a

If I remove that, and compare FPS, then the VBO performance is
slightly
better than the displaylist
