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.

bool glm::all ( vecType< bool > const & v )

Returns true if all components of x are true.

Template Parameters:

vecType Boolean vector types.

See also:: GLSL all man page; GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

bool glm::any ( vecType< bool > const & v )

Returns true if any component of x is true.

Template Parameters:

vecType Boolean vector types.

See also:: GLSL any man page; GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

vecType::bool_type glm::equal	(	vecType const &	x,
		vecType const &	y
	)

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

Template Parameters:

vecType Floating-point, integer or boolean vector types.

See also:: GLSL equal man page; GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

vecType::bool_type glm::greaterThan	(	vecType const &	x,
		vecType const &	y
	)

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

Template Parameters:

vecType Floating-point or integer vector types.

See also:: GLSL greaterThan man page; GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

vecType::bool_type glm::greaterThanEqual	(	vecType const &	x,
		vecType const &	y
	)

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

Template Parameters:

vecType Floating-point or integer vector types.

See also:: GLSL greaterThanEqual man page; GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

vecType::bool_type glm::lessThan	(	vecType const &	x,
		vecType const &	y
	)

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

Template Parameters:

vecType Floating-point or integer vector types.

See also:: GLSL lessThan man page; GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

vecType::bool_type glm::lessThanEqual	(	vecType const &	x,
		vecType const &	y
	)

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

Template Parameters:

vecType Floating-point or integer vector types.

See also:: GLSL lessThanEqual man page; GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

vecType<bool> glm::not_ ( vecType< bool > 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:

vecType Boolean vector types.

See also:: GLSL not man page; GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

vecType::bool_type glm::notEqual	(	vecType const &	x,
		vecType const &	y
	)

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

Template Parameters:

vecType Floating-point, integer or boolean vector types.
