Detailed Description

template<class BoxScalarType>
class vcg::Box3< BoxScalarType >

The templated class for representing a point in 3D space. The class is templated over the ScalarType class that is used to represent coordinates. All the usual operator overloading (* + - ...) is present.

Templated class for 3D boxes. This is the class for definition of a axis aligned bounding box in 3D space. It is stored just as two Point3

Parameters

BoxScalarType (template parameter) Specifies the type of scalar used to represent coords.

Member Function Documentation

◆ Add() [1/4]

template<class BoxScalarType >

void vcg::Box3< BoxScalarType >::Add ( const Box3< BoxScalarType > & b )

inline

Modify the current bbox to contain also the passed box. Adding a null bounding box does nothing

◆ Add() [2/4]

template<class BoxScalarType >

void vcg::Box3< BoxScalarType >::Add	(	const Matrix44< BoxScalarType > &	m,
		const Box3< BoxScalarType > &	b
	)

inline

Modify the current bbox to contain also the box b transformed according to the matrix m

◆ Add() [3/4]

template<class BoxScalarType >

void vcg::Box3< BoxScalarType >::Add ( const Point3< BoxScalarType > & p )

inline

Modify the current bbox to contain also the passed point

◆ Add() [4/4]

template<class BoxScalarType >

void vcg::Box3< BoxScalarType >::Add	(	const Point3< BoxScalarType > &	p,
		const BoxScalarType	radius
	)

inline

Modify the current bbox to contain also the passed sphere

◆ Collide()

template<class BoxScalarType >

bool vcg::Box3< BoxScalarType >::Collide ( const Box3< BoxScalarType > & b ) const

inline

Verifica se due bounding box collidono cioe' se hanno una intersezione non vuota. Per esempio due bounding box adiacenti non collidono.

Parameters

b	A bounding box

Returns: True se collidoo, false altrimenti

◆ Intersect()

template<class BoxScalarType >

void vcg::Box3< BoxScalarType >::Intersect ( const Box3< BoxScalarType > & b )

inline

Calcola l'intersezione tra due bounding box. Al bounding box viene assegnato il valore risultante.

Parameters

b	Il bounding box con il quale si vuole effettuare l'intersezione

◆ IsEmpty()

template<class BoxScalarType >

bool vcg::Box3< BoxScalarType >::IsEmpty ( ) const

inline

return true if the box is empty (e.g. if min == max)

◆ IsIn()

template<class BoxScalarType >

bool vcg::Box3< BoxScalarType >::IsIn ( const Point3< BoxScalarType > & p ) const

inline

true if the point belong to the closed box

◆ IsInEx()

template<class BoxScalarType >

bool vcg::Box3< BoxScalarType >::IsInEx ( const Point3< BoxScalarType > & p ) const

inline

true if the point belong to the open box (open on the max side) e.g. if p in [min,max)

◆ IsNull()

template<class BoxScalarType >

bool vcg::Box3< BoxScalarType >::IsNull ( ) const

inline

return true if the box is null (e.g. invalid or not initialized);

◆ Offset() [1/2]

template<class BoxScalarType >

void vcg::Box3< BoxScalarType >::Offset ( const BoxScalarType s )

inline

Offset of a vector (s,s,s)

◆ Offset() [2/2]

template<class BoxScalarType >

void vcg::Box3< BoxScalarType >::Offset ( const Point3< BoxScalarType > & delta )

inline

Offset the two corner of the box of a vector delta. adding delta to max and -delta to min.

Parameters

delta offset vector

◆ Translate()

template<class BoxScalarType >

void vcg::Box3< BoxScalarType >::Translate ( const Point3< BoxScalarType > & p )

inline

Trasla il bounding box di un valore definito dal parametro.

Parameters

p	Il bounding box trasla sulla x e sulla y in base alle coordinate del parametro
