Hi again, I have integrated an OSG viewer in an existing application and have
gotten the viewer to display a model correctly. I now wanted to implement some
picking, and I have been using the osgkeyboardmouse example for this.
My problem is that whenever I click on something the deconstructor for
"intersection" causes a "Heap pointer out of local" error when "intersection"
goes out of scope.
The code snippet is the following (from osgkeyboardmouse):
---------------
osgUtil::IntersectionVisitor iv(picker);
viewer->getCamera()->accept(iv);
if (picker->containsIntersections())
{
osgUtil::LineSegmentIntersector::Intersection intersection =
picker->getFirstIntersection();
osg::notify(osg::NOTICE)<<"Picked
"<<intersection.localIntersectionPoint<<std::endl;
osg::NodePath& nodePath = intersection.nodePath;
node = (nodePath.size()>=1)?nodePath[nodePath.size()-1]:0;
parent =
(nodePath.size()>=2)?dynamic_cast<osg::Group*>(nodePath[nodePath.size()-2]):0;
if (node) std::cout<<" Hits "<<node->className()<<" nodePath
size"<<nodePath.size()<<std::endl;
toggleScribe(parent, node);
}
-----------------
I have tried integrating the osgkeyboardmouse in the osgviewermfc example, and
there it works fine, so I'm mostly suspecting that the problem lies with my
existing application, but if anyone have tried anything similar I would like to
hear any ideas you might have.
