Detailed Description

VisibilityGroup renders (traverses) it's children only when the camera is inside a specified visibility volume. The visibility volume is intersected with a line segment that extends from the current camera's eye-point along the view vector for a given segment length. If an intersection is detected then the node's children are traversed.

osg::Node* osgSim::VisibilityGroup::getVisibilityVolume ( )

inline

Get the subgraph that is intersected for the visibility determination.

Definition at line 47 of file VisibilityGroup.h.

const osg::Node* osgSim::VisibilityGroup::getVisibilityVolume ( ) const

inline

Get the const subgraph that is intersected for the visibility determination.

Definition at line 50 of file VisibilityGroup.h.

osg::Node::NodeMask osgSim::VisibilityGroup::getVolumeIntersectionMask ( ) const

inline

Get the traversal mask for the intersection testing.

osgSim::VisibilityGroup::META_Node	(	osgSim	,
		VisibilityGroup
	)

void osgSim::VisibilityGroup::setSegmentLength ( float length )

inline

Set the length of the intersection segment. The segments extends this many database units from the camera eye-point along the look vector. If this is left at zero then the diameter of the bounding sphere of the visibility volume is used.

Definition at line 61 of file VisibilityGroup.h.

void osgSim::VisibilityGroup::setVisibilityVolume ( osg::Node * node )

inline

Set the subgraph that is intersected for the visibility determination.

Definition at line 44 of file VisibilityGroup.h.

void osgSim::VisibilityGroup::setVolumeIntersectionMask ( osg::Node::NodeMask mask )

inline

Set the traversal mask for the intersection testing.

Definition at line 53 of file VisibilityGroup.h.

virtual void osgSim::VisibilityGroup::traverse ( osg::NodeVisitor & )

virtual

Traverse downwards : calls children's accept method with NodeVisitor.

Reimplemented from osg::Group.
