Dear Osgers,
Based on my exploration I found interesting behavior of PagedLOD
traversal. In some condition the PagedLOD displays incorrect child
(child out of specified distance range).
I am curious if I did something wrong, if it is intended design or if I
found a bug.
Please imagine following

Then OSG can't find the osgdb_osg.dll file at runtime. Troubleshoot why.

The filename is a .osg file.
I couldn't make heads or tails of that link you provided; is it telling me to
set an environment variable or send it a compiler option?

For what it's worth, I learned this the hard way.
64-bit symbols lack the leading underscore. So, if you dump the lib symbol
table, you
can tell if you're working with 64-bit or 32-bit library code.

I was reading more into that e-book tutorial listed earlier in this thread. I

Hi Vincent,
The osgViewer library has built in support for doing multiple
screens/contexts, I would recommend using this, rather than trying to
cook your own solution for it. It is possible to have your app

I have a simple problem (I think...) but I just can't find an answer.
The problem is this: Given an osg scene and a camera I want a list

Can I do it with a cull visitor?
Maybe I need a Polytope intersector?
Help would be much appreciated.
Hi,
answering my own question as I figured it out, but not sure if there's a better
sollution.
I created an UpdateCallback without calling traverse( node , nodeVisitor ) in
the operator() method.
I attached this callback to all but one Group, in the example of the original
post to group2.

I followed the same instruction without success. I think the problem is the

The Readme says we need:

Cg 2.0 Toolkit
But while I was compiling I had several errors, then I tried to install the
dependiences and install the collada-dom-2.3 version.

This approach works well, but it works not on run time, but
