Detailed Description

InteresectionVisitor is used to testing for intersections with the scene, traversing the scene using generic osgUtil::Intersector's to test against the scene. To implement different types of intersection techniques, one implements custom versions of the osgUtil::Intersector, and then pass the constructed intersector to the IntersectionVisitor.

virtual void osgUtil::IntersectionVisitor::reset

(

)

[virtual]

Method to call to reset visitor. Useful if your visitor accumulates state during a traversal, and you plan to reuse the visitor. To flush that state for the next traversal: call reset() prior to each traversal.

Reimplemented from osg::NodeVisitor.

void osgUtil::IntersectionVisitor::setIntersector

(

Intersector *

intersector

)

Set the intersector that will be used to intersect with the scene, and to store any hits that occur.

Intersector* osgUtil::IntersectionVisitor::getIntersector

(

)

[inline]

Get the intersector that will be used to intersect with the scene, and to store any hits that occur.

const Intersector* osgUtil::IntersectionVisitor::getIntersector

(

)

const [inline]

Get the const intersector that will be used to intersect with the scene, and to store any hits that occur.

void osgUtil::IntersectionVisitor::setReadCallback

(

ReadCallback *

rc

)

[inline]

Set the read callback.

ReadCallback* osgUtil::IntersectionVisitor::getReadCallback

(

[inline]

Get the read callback.

const ReadCallback* osgUtil::IntersectionVisitor::getReadCallback

(

)

const [inline]
