Hello Oliver,
You say you are using osg version 2.8.3 and osg binaries.
The only Windows binaries for 2.8.3 I could find on openscenegraph.org are
the following:
http://www.openscenegraph.org/downloads/stable_releases/OpenSceneGraph-2.8.3/binaries/Windows/VisualStudio8/
They are for Visual C++ version 8.
The stack trace that you provide mentions msvcr90.dll. This is the runtime
dll for Visual C++ version 9.
If you are using Visual C++ version 9 then you need to use osg binaries for
Visual C++ version 9.
Regards,
Peter

Subject: Re: [osg-users] problem with osgUtil::IntersectVisitor
andosg::LineSegment
Hello Martin,
I'm using osg version 2.8.3 with visual C++ express, and my os is windows
xp. I also tried the basic examples I could find on tutorials and on the
osg website but I still have the same problem :(. I guess it comes from my
configuration.
I used this tutorial to install osg :
http://dwightdesign.com/2009/05/installing-openscenegraph-280/.
I used the prebuilt version of osg.
Everything I tried on osg worked perfectly except for this function (I
also tried polytope intersector, height above terrain... but I got the
same error).
You're right it looks like the program is allocating all the memory to the
hitlist (the size is over 4 billion). However it looks like the apply
method works : I've fot a number of intersections but I just can't have
access to the intersection points coordinates.
The code is as follows. m_node points to a model I loaded. The model works
fine (it's basically a set of (a lot of) points joined by panels).
osg::LineSegment *ls = new
osg::LineSegment(osg::Vec3d(-5,-5,-5),osg::Vec3d(5,5,5));
osgUtil::IntersectVisitor *iv = new osgUtil::IntersectVisitor();
iv->addLineSegment(ls);
iv->apply(*m_node);
std::cout << iv->getNumHits(ls) << " intersection points (hits)." <<
std::endl; //result = 6
osgUtil::IntersectVisitor::HitList& hitlist = iv->getHitList(ls);
std::cout << "size : " << hitlist.size() << std::endl;
//std::vector<osgUtil::Hit>::iterator itr = hitlist.begin();
hitlist[0].getWorldIntersectPoint(); //causes unhandled exception...
Thanks for your help,
Olivier

Hello,
I checked the installation of osg. I was not mixing debug and release. But
to be sure I uninstalled debug. However I still have the same probem as
before. I copied the stack trace if it helps. Do you have any idea ?
