Detailed Description

template<class T>
struct EBGeometry::RayDetail::Piece< T >

Where a ray is inside a convex piece: [m_in, m_out], with the outward normals there; empty if m_in > m_out.

Internal helper; not part of the public API.

Template Parameters

T	Floating-point precision.

Member Function Documentation

clip()

template<class T >

void EBGeometry::RayDetail::Piece< T >::clip ( const RayT< T > &  a_ray, const Vec3T< T > &  a_n, const T  a_d  )

inlinenoexcept

Clip to the half-space n . x <= d.

Parameters

[in]	a_ray	The ray.
[in]	a_n	Outward normal, unit length.
[in]	a_d	Offset.

empty()

template<class T >

static Piece EBGeometry::RayDetail::Piece< T >::empty ( )

inlinestaticnoexcept

An empty piece.

Returns

The piece.

hit()

template<class T >

bool EBGeometry::RayDetail::Piece< T >::hit ( ) const

inlinenoexcept

Whether the ray meets the piece.

Returns

m_in <= m_out.

unite()

template<class T >

void EBGeometry::RayDetail::Piece< T >::unite ( const Piece< T > &  a_other )

inlinenoexcept

Parameters

[in]

a_other

The other piece.
