Function Documentation

getOverlappingVolume() [1/2]

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.

getOverlappingVolume() [2/2]

template<class T >

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

noexcept

Compute the overlapping volume between two bounding spheres.

Template Parameters

T	Floating-point precision.

Parameters

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

Returns

Overlap volume; zero if the spheres do not intersect.

intersects() [1/2]

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.

intersects() [2/2]

template<class T >

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

noexcept

Test whether two bounding spheres overlap.

Template Parameters

T	Floating-point precision.

Parameters

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

Returns

True if the spheres intersect, false otherwise.
