Function Documentation

GLM_FUNC_DECL vecType::value_type glm::angle	(	vecType const &	x,
		vecType const &	y
	)

Returns the absolute angle between two vectors.

Parameters need to be normalized.

GLM_FUNC_DECL T glm::orientedAngle	(	tvec2< T, P > const &	x,
		tvec2< T, P > const &	y
	)

Returns the oriented angle between two 2d vectors.

Parameters need to be normalized.
