示例1: computeIntersections
bool Widget::computeIntersections(osgGA::EventVisitor* ev, osgGA::GUIEventAdapter* event, Intersections& intersections, osg::Node::NodeMask traversalMask) const
{
osgGA::GUIActionAdapter* aa = ev ? ev->getActionAdapter() : 0;
osgUtil::LineSegmentIntersector::Intersections source_intersections;
if (aa && aa->computeIntersections(*event, ev->getNodePath(), source_intersections, traversalMask))
{
typedef std::vector<const osgUtil::LineSegmentIntersector::Intersection*> IntersectionPointerList;
IntersectionPointerList intersectionsToSort;
// populate the temporay vector of poiners to the original intersection pointers.
for(osgUtil::LineSegmentIntersector::Intersections::iterator itr = source_intersections.begin();
itr != source_intersections.end();
++itr)
{
if (itr->drawable->getName()!="DepthSetPanel")
{
intersectionsToSort.push_back(&(*itr));
}
}
// sort the pointer list into order based on child traversal order, to be consistent with osgUI rendering order.
std::sort(intersectionsToSort.begin(), intersectionsToSort.end(), SortTraversalOrder());
// copy the pointers to final Intersection container
for(IntersectionPointerList::iterator itr = intersectionsToSort.begin();
