Function Documentation

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

Returns the absolute angle between two vectors Parameters need to be normalized.

From GLM_GTX_vector_angle extension

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

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

From GLM_GTX_vector_angle extension.

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

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

Parameters need to be normalized. From GLM_GTX_vector_angle extension.
