Detailed Description

Generic functions in the Math API targeted to static vector-like sequences.

They help, together with the Basic Math Functors in the Math API to implement the operators and functions on vector-like data types, whose number of elements are known at compile time. Thus, optimizations like loop unrolling are possible. These generic functions and the functors are in principle inline.

template<class Vector , class UnaryFunctor >

void mi::math::general::for_each	(	Vector &	vec,
		UnaryFunctor	f
	)

inline

Generic transform function that applies a unary functor (in-place).

The transform function applies the unary functor f to each element of the vector-like value vec, which is modifiable.

The size of vec is available as compile-time constant Vector::SIZE.

template<class Vector1 , class Vector2 , class BinaryFunctor >

void mi::math::general::for_each	(	Vector1 &	vec1,
		const Vector2 &	vec2,
		BinaryFunctor	f
	)

inline

Generic transform function that applies a binary functor (in-place).

The transform function applies the binary functor f to each pair of matching elements of the vector-like values vec1 and vec2, where vec1 is modifiable and vec2 not.

The size of vec1 is available as compile-time constant Vector::SIZE and has to be the same as for vec2.

template<class Vector , class ResultVector , class UnaryFunctor >

void mi::math::general::transform	(	const Vector &	vec,
		ResultVector &	result,
		UnaryFunctor	f
	)

inline

Generic transform function that applies a unary functor (return value).

The function applies the unary functor f to each element of the vector-like value vec and assigns the result to the same coordinate in the vector-like value result.

Both vector values have to be of the same size, available as compile-time constant Vector::SIZE.

template<class Vector1 , class Vector2 , class ResultVector , class BinaryFunctor >

void mi::math::general::transform	(	const Vector1 &	vec1,
		const Vector2 &	vec2,
		ResultVector &	result,
		BinaryFunctor	f
	)

inline

Generic transform function that applies a binary functor (return value).

The function appliex the binary functor f to each pair of matching elements of the vector-like values vec1 and vec2 and assigns the result to the same coordinate in the vector-like value result.

All vector values have to be of the same size, available as compile-time constant Vector1::SIZE.

template<class Scalar , class Vector , class ResultVector , class BinaryFunctor >

void mi::math::general::transform_left_scalar	(	const Scalar &	s,
		const Vector &	vec,
		ResultVector &	result,
		BinaryFunctor	f
	)

inline

Generic transform function that applies a binary functor (return value, LHS scalar).

The function applies the binary functor f to each element of the vector-like values vec and assigns the result to the same coordinate in the vector-like value result. The scalar value s is passed as a left argument to f and the vector element is passed as a right argument.

All vector values have to be of the same size, available as compile-time constant Vector::SIZE.

template<class Scalar , class Vector , class ResultVector , class BinaryFunctor >

void mi::math::general::transform_right_scalar	(	const Vector &	vec,
		const Scalar &	s,
		ResultVector &	result,
		BinaryFunctor	f
	)

inline

Generic transform function that applies a binary functor (return value, RHS scalar).

The function applies the binary functor f to each element of the vector-like values vec and assigns the result to the same coordinate in the vector-like value result. The scalar value s is passed as a left argument to f and the vector element is passed as a right argument.

All vector values have to be of the same size, available as compile-time constant Vector::SIZE.
