Member Function Documentation

◆ addLineSegment()

void osgUtil::IntersectVisitor::addLineSegment ( osg::LineSegment *  seg)

Add a line segment to use for intersection testing during scene traversal. Note, a maximum of 32 line segments can be added to a IntersectVistor, adding more than this will result in warning being emitted to the console and the excess segments being ignored.

◆ apply() [1/8]

virtual void osgUtil::IntersectVisitor::apply ( osg::Billboard &  node)
virtual

Reimplemented from osg::NodeVisitor.

◆ apply() [2/8]

Reimplemented from osg::NodeVisitor.

◆ apply() [6/8]

virtual void osgUtil::IntersectVisitor::apply ( osg::Node &  )
virtual

Reimplemented from osg::NodeVisitor.

◆ apply() [7/8]

◆ getDistanceToEyePoint()

virtual float osgUtil::IntersectVisitor::getDistanceToEyePoint ( const osg::Vec3 &  pos,
bool  withLODScale 
) const
virtual

Get the distance from a point to the eye point, distance value in local coordinate system. This is calculated using the pseudo-EyePoint (above) when doing LOD calculcations.

Reimplemented from osg::NodeVisitor.

◆ getEyePoint()

virtual osg::Vec3 osgUtil::IntersectVisitor::getEyePoint ( ) const
virtual

Get the eye point in local coordinates. Note, not all NodeVisitor implement this method, it is mainly cull visitors which will implement.

Reimplemented from osg::NodeVisitor.

◆ setEyePoint()

void osgUtil::IntersectVisitor::setEyePoint ( const osg::Vec3 &  eye)
inline

Set the eye point in local coordinates. This is a pseudo-EyePoint for billboarding and LOD purposes. It is copied from the Start point of the most-recently-added segment of the intersection ray set (IntersectState::_segList).
