Function Documentation

genType::value_type glm::gtx::fast_square_root::fastDistance ( genType const &  x,
genType const &  y 
)

Faster than the common distance function but less accurate.

From GLM_GTX_fast_square_root extension.

genType glm::gtx::fast_square_root::fastInverseSqrt ( genType const &  x)

Faster than the common inversesqrt function but less accurate.

From GLM_GTX_fast_square_root extension.

genType::value_type glm::gtx::fast_square_root::fastLength ( genType const &  x)

Faster than the common length function but less accurate.

From GLM_GTX_fast_square_root extension.

genType glm::gtx::fast_square_root::fastNormalize ( genType const &  x)

Faster than the common normalize function but less accurate.

From GLM_GTX_fast_square_root extension.

genType glm::gtx::fast_square_root::fastSqrt ( genType const &  x)

Faster than the common sqrt function but less accurate.

From GLM_GTX_fast_square_root extension.
