Detailed Description

template<typename VT>
class osg::BoundingBoxImpl< VT >

General purpose axis-aligned bounding box class for enclosing objects/vertices. Bounds leaf objects in a scene such as osg::Drawable objects. Used for frustum culling etc.

Member Function Documentation

◆ center()

template<typename VT>

const vec_type osg::BoundingBoxImpl< VT >::center ( ) const

inline

Calculates and returns the bounding box center.

Referenced by osg::BoundingSphereImpl< VT >::expandBy(), and osg::BoundingSphereImpl< VT >::expandRadiusBy().

◆ contains() [1/2]

template<typename VT>

bool osg::BoundingBoxImpl< VT >::contains ( const vec_type & v ) const

inline

Returns true if this bounding box contains the specified coordinate.

◆ contains() [2/2]

template<typename VT>

bool osg::BoundingBoxImpl< VT >::contains	(	const vec_type &	v,
		value_type	epsilon ) const

inline

Returns true if this bounding box contains the specified coordinate allowing for specific epsilon.

◆ corner()

template<typename VT>

const vec_type osg::BoundingBoxImpl< VT >::corner ( unsigned int pos ) const

inline

Returns a specific corner of the bounding box. pos specifies the corner as a number between 0 and 7. Each bit selects an axis, X, Y, or Z from least- to most-significant. Unset bits select the minimum value for that axis, and set bits select the maximum.

◆ expandBy() [1/4]

template<typename VT>

void osg::BoundingBoxImpl< VT >::expandBy ( const BoundingBoxImpl< VT > & bb )

inline

Expands this bounding box to include the given bounding box. If this box is uninitialized, set it equal to bb.

◆ expandBy() [2/4]

template<typename VT>

template<typename BST>

void osg::BoundingBoxImpl< VT >::expandBy ( const BoundingSphereImpl< BST > & sh )

Expands this bounding box to include the given sphere. If this box is uninitialized, set it to include sh.

◆ expandBy() [3/4]

template<typename VT>

void osg::BoundingBoxImpl< VT >::expandBy ( const vec_type & v )

inline

Expands the bounding box to include the given coordinate. If the box is uninitialized, set its min and max extents to v.

Referenced by osg::BoundingSphereImpl< VT >::expandBy().

◆ expandBy() [4/4]

template<typename VT>

void osg::BoundingBoxImpl< VT >::expandBy	(	value_type	x,
		value_type	y,
		value_type	z )

inline

Expands the bounding box to include the given coordinate. If the box is uninitialized, set its min and max extents to Vec3(x,y,z).

◆ init()

template<typename VT>

void osg::BoundingBoxImpl< VT >::init ( )

inline

Clear the bounding box. Erases existing minimum and maximum extents.

◆ intersect()

inline

Returns the intersection of this bounding box and the specified bounding box.

◆ intersects()

template<typename VT>

bool osg::BoundingBoxImpl< VT >::intersects ( const BoundingBoxImpl< VT > & bb ) const
