Detailed Description

Namespace encapsulating bounding volume types for use with bounding volume hierarchies.

Function Documentation

getOverlappingVolume()

template<class T >

T EBGeometry::BoundingVolumes::getOverlappingVolume ( const AABBT< T > &  a_u, const AABBT< T > &  a_v  )

noexcept

Compute the overlapping volume between two axis-aligned bounding boxes.

Template Parameters

T	Floating-point precision.

Parameters

[in]	a_u	One bounding box.
[in]	a_v	The other bounding box.

Returns

Overlap volume; zero if the boxes do not intersect.

intersects()

template<class T >

bool EBGeometry::BoundingVolumes::intersects ( const AABBT< T > &  a_u, const AABBT< T > &  a_v  )

noexcept

Test whether two axis-aligned bounding boxes overlap.

Template Parameters

T	Floating-point precision.

Parameters

[in]	a_u	One bounding box.
[in]	a_v	The other bounding box.

Returns

True if the boxes intersect, false otherwise. Boxes that only touch do not intersect.

operator<<()

template<class T >

std::ostream & EBGeometry::BoundingVolumes::operator<< ( std::ostream &  a_os, const AABBT< T > &  a_aabb  )

inline

Print a bounding box as (low corner, high corner).

Template Parameters

T	Floating-point precision.

Parameters

[in,out]	a_os	Output stream.
[in]	a_aabb	Bounding box to print.

Returns

Reference to the output stream after insertion.
