glm::angle
GLM_FUNC_DECL T angle(vec< L, T, Q > const &x, vec< L, T, Q > const &y)
Returns the absolute angle between two vectors.
glm::orientedAngle
GLM_FUNC_DECL T 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.
