Detailed Description

Relational and equality operators (<, <=, >, >=, ==, !=) are defined to operate on scalars and produce scalar Boolean results.

For vector results, use the following built-in functions.

In all cases, the sizes of all the input and return vectors for any particular call must match.

Include <glm/vector_relational.hpp> to use these core features.

(

vec< L, bool, Q > const &

v

)

Returns true if all components of x are true.

Template Parameters

L	An integer between 1 and 4 included that qualify the dimension of the vector.

GLM_FUNC_DECL GLM_CONSTEXPR vec<L, bool, Q> glm::greaterThan	(	vec< L, T, Q > const &	x,
		vec< L, T, Q > const &	y
	)

		vec< L, T, Q > const &	y
	)

Returns the component-wise comparison of result x >= y.

lessThan()

GLM_FUNC_DECL GLM_CONSTEXPR vec<L, bool, Q> glm::lessThan	(	vec< L, T, Q > const &	x,
		vec< L, T, Q > const &	y
	)

Returns the component-wise comparison result of x < y.

GLM_FUNC_DECL GLM_CONSTEXPR vec<L, bool, Q> glm::lessThanEqual	(	vec< L, T, Q > const &	x,
		vec< L, T, Q > const &	y
	)

Returns the component-wise comparison of result x <= y.

not_()

GLM_FUNC_DECL GLM_CONSTEXPR vec<L, bool, Q> glm::not_

(

vec< L, bool, Q > const &

v

)

Returns the component-wise logical complement of x.

/!\ Because of language incompatibilities between C++ and GLSL, GLM defines the function not but not_ instead.

Template Parameters

L	An integer between 1 and 4 included that qualify the dimension of the vector.

		vec< L, T, Q > const &	y
	)

Returns the component-wise comparison of result x != y.

Template Parameters

L	An integer between 1 and 4 included that qualify the dimension of the vector.
T	A floating-point, integer or bool scalar type.
