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.

		vecType< T, P > const &	y
	)

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

		vecType< T, P > const &	y
	)

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

Template Parameters

GLM_FUNC_DECL vecType<bool, P> glm::not_

(

vecType< bool, P > 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.
