Function Documentation

template<typename genType >
genType::value_type glm::fastDistance ( genType const &  x,
genType const &  y 
)

Faster than the common distance function but less accurate. From GLM_GTX_fast_square_root extension.

template<typename genType >
genType glm::fastInverseSqrt ( genType const &  x)

Faster than the common inversesqrt function but less accurate. From GLM_GTX_fast_square_root extension.

template<typename genType >
genType::value_type glm::fastLength ( genType const &  x)

Faster than the common length function but less accurate. From GLM_GTX_fast_square_root extension.

template<typename genType >
genType glm::fastNormalize ( genType const &  x)

Faster than the common normalize function but less accurate. From GLM_GTX_fast_square_root extension.

template<typename genType >
genType glm::fastSqrt ( genType const &  x)

Faster than the common sqrt function but less accurate. From GLM_GTX_fast_square_root extension.
