Function Documentation

template<typename vecType >

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.

template<typename T , precision P>

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

Returns the oriented angle between two 2d vectors Parameters need to be normalized.

template<typename T , precision P>

GLM_FUNC_DECL T glm::orientedAngle	(	detail::tvec3< T, P > const &	x,
		detail::tvec3< T, P > const &	y,
		detail::tvec3< T, P > const &	ref
	)

Returns the oriented angle between two 3d vectors based from a reference axis. Parameters need to be normalized.
