Hi all,
I'm using C# to implement picking in OSG for my project.
I created a OsgUtil.PolytopeIntersector object (picker) in my pick method and
registered it to a OsgUtil.IntersectionVisitor. The picker seems to work when I
called OsgUtil.PolytopeIntersector.Intersection intersection =
picker.getFirstIntersection(). But I'm stuck here, because I couldn't see any
methods that obtain the picked nodes from the intersection object.
In C++, it is simple to do so:
osgUtil::LineSegmentIntersector::Intersection intersection =
picker->getFirstIntersection();
osg::NodePath& nodePath = intersection.nodePath;
osg::Node* node = (nodePath.size()>=1)?nodePath[nodePath.size()-1]:0;
osg::Group* parent =
(nodePath.size()>=2)?dynamic_cast<osg::Group*>(nodePath[nodePath.size()-2]):0;
If anyone knows how to obtain picked nodes using C#, please give me some
advice. Your help is highly appreciated!
Regards,
Ke Li
