Member Function Documentation

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.

virtual

Reimplemented from osg::NodeVisitor.

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

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

	)		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.

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.
