Detailed Description

Function Documentation

depth()

template<typename V >

auto MR::depth ( const Box< V > & box )

inline

returns size along z axis

findSortedBoxDims()

template<typename V >

auto MR::findSortedBoxDims ( const Box< V > & box ) -> typename VectorTraits<V>::template ChangeBaseType<int>

inline

returns a vector with unique integer values, each representing a dimension of the box; the dimensions are sorted according to the sizes of the box along each dimension: the dimension with the smallest size is first, largest size - last. E.g. findSortedBoxDims( Box3f( {0, 0, 0}, {2, 1, 3} ) ) == Vector3i(1, 0, 2)

get() [1/2]

template<size_t I, typename V >

V & MR::get ( Box< V > & box )

constexprnoexcept

get() [2/2]

template<size_t I, typename V >

const V & MR::get ( const Box< V > & box )

constexprnoexcept

get<0> returns min, get<1> returns max

getCorners() [1/2]

template<typename T >

std::array< Vector2< T >, 4 > MR::getCorners ( const Box< Vector2< T > > & box )

inline

getCorners() [2/2]

template<typename T >

std::array< Vector3< T >, 8 > MR::getCorners ( const Box< Vector3< T > > & box )

inline

returns all corners of given box

getTouchPlanes()

template<typename V >

MinMax< typename Box< V >::T > MR::getTouchPlanes	(	const Box< V > &	box,
		const V &	n )

among all planes with given normal and arbitrary shift: dot(n,x) = d finds minimal and maximal touching planes for given box, and returns them as { min_d, max_d }

height()

template<typename V >

auto MR::height ( const Box< V > & box )

inline

returns size along y axis

transformed() [1/2]

template<typename V >

Box< V > MR::transformed ( const Box< V > & box, const AffineXf< V > & xf )

inline

find the tightest box enclosing this one after transformation

transformed() [2/2]

template<typename V >

Box< V > MR::transformed ( const Box< V > & box, const AffineXf< V > * xf )

inline

this version returns input box as is if pointer to transformation is null

width()

template<typename V >

auto MR::width ( const Box< V > & box )

inline

returns size along x axis
