Compute angle between vectors

Function Documentation

angle()

GLM_FUNC_DECL T glm::angle	(	vec< L, T, Q > const &	x,
		vec< L, T, Q > const &	y
	)

Returns the absolute angle between two vectors.

Parameters need to be normalized.

orientedAngle() [1/2]

GLM_FUNC_DECL T glm::orientedAngle	(	vec< 2, T, Q > const &	x,
		vec< 2, T, Q > const &	y
	)

Returns the oriented angle between two 2d vectors.

Parameters need to be normalized.

orientedAngle() [2/2]

GLM_FUNC_DECL T glm::orientedAngle	(	vec< 3, T, Q > const &	x,
		vec< 3, T, Q > const &	y,
		vec< 3, T, Q > const &	ref
	)

Returns the oriented angle between two 3d vectors based from a reference axis.

Parameters need to be normalized.
