Detailed Description

A simplified version of OSG's LOD node, which simply switches all its on or off based on a single distance. It also allows an extra distance to globally increase the viewable distance for all node of this type.

Constructor & Destructor Documentation

GroupLOD::GroupLOD	(	const GroupLOD &	GroupLOD,
		const CopyOp &	copyop = CopyOp::SHALLOW_COPY
	)

Copy constructor using CopyOp to manage deep vs shallow copy.

Member Function Documentation

const Vec3& osg::GroupLOD::getCenter ( ) const

inline

return the LOD center point.

float osg::GroupLOD::getDistance ( ) const

inline

returns the maximum visible distance

static float osg::GroupLOD::getGroupDistance ( )

inlinestatic

Gets the (global, extra) visible distance for nodes of this type.

value_type osg::GroupLOD::getRadius ( ) const

inline

Get the object-space radius of the volume enclosed by the LOD.

void osg::GroupLOD::setCenter ( const Vec3 &  center )

inline

Set the LOD center point.

void osg::GroupLOD::setDistance ( float  max )

inline

Sets the maximum visible distance for this node.

static void osg::GroupLOD::setGroupDistance ( float  max )

inlinestatic

Sets the (global, extra) visible distance for nodes of this type.

void osg::GroupLOD::setRadius ( value_type  radius )

inline

Set the object-space reference radius of the volume enclosed by the LOD. Used to determine the bounding sphere of the LOD in the absence of any children.
