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.

)

Returns the component-wise logical complement of x.

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