Detailed Description

An axis-aligned bounding box; that is, a minimum and maximum coordinate triple.

This box is always axis-aligned. If you need a more general bounding box, try BoundingHexahedron.

Definition at line 29 of file boundingBox.h.

Constructor & Destructor Documentation

◆ BoundingBox() [1/2]

BoundingBox::BoundingBox ( )

inline

Constructs an empty box object.

Definition at line 18 of file boundingBox.I.

◆ BoundingBox() [2/2]

BoundingBox::BoundingBox	(	const LPoint3 &	min,
		const LPoint3 &	max
	)

inlineexplicit

Constructs a specific box object.

Definition at line 25 of file boundingBox.I.

Member Function Documentation

◆ as_bounding_box()

const BoundingBox * BoundingBox::as_bounding_box ( ) const

virtual

Virtual downcast method.

Returns this object as a pointer of the indicated type, if it is in fact that type. Returns NULL if it is not that type.

Reimplemented from BoundingVolume.

Definition at line 132 of file boundingBox.cxx.

◆ get_maxq()

const LPoint3 & BoundingBox::get_maxq ( ) const

inline

An inline accessor for the maximum value.

get_max() would also work, but it is a virtual non-inline method.

Definition at line 52 of file boundingBox.I.

◆ get_minq()

const LPoint3 & BoundingBox::get_minq ( ) const

inline

An inline accessor for the minimum value.

get_min() would also work, but it is a virtual non-inline method.

Definition at line 41 of file boundingBox.I.

◆ set_min_max()

void BoundingBox::set_min_max	(	const LPoint3 &	min,
		const LPoint3 &	max
	)

inline

Sets the min and max point of the rectangular solid.

Definition at line 102 of file boundingBox.I.

Member Data Documentation

◆ get_num_planes

int BoundingBox::get_num_planes

inline

Returns 6: the number of faces of a rectangular solid.

Definition at line 54 of file boundingBox.h.

◆ get_num_points

int BoundingBox::get_num_points

inline

Returns 8: the number of vertices of a rectangular solid.

Definition at line 51 of file boundingBox.h.

◆ get_plane

LPlane BoundingBox::get_plane

inline

Returns the nth face of the rectangular solid.

Definition at line 54 of file boundingBox.h.

◆ get_point

LPoint3 BoundingBox::get_point

inline

Returns the nth vertex of the rectangular solid.

Definition at line 51 of file boundingBox.h.
