Function Documentation

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

Returns the absolute angle between x and y.

Parameters need to be normalized. From GLM_GTX_vector_angle extension

vecType::value_type glm::gtx::vector_angle::orientedAngle	(	vecType const &	x,
		vecType const &	y
	)

Returns the oriented angle between x and y Parameters need to be normalized.

From GLM_GTX_vector_angle extension.

vecType::value_type glm::gtx::vector_angle::orientedAngleFromRef	(	vecType const &	x,
		vecType const &	y,
		detail::tvec3< typename vecType::value_type > const &	ref
	)

Returns the orientation of a two vector base from a normal.

Parameters need to be normalized. From GLM_GTX_vector_angle extension.
