glm::fastDistance

GLM_FUNC_DECL T fastDistance(vecType< T, P > const &x, vecType< T, P > const &y)

Faster than the common distance function but less accurate.

glm::fastNormalize

GLM_FUNC_DECL genType fastNormalize(genType const &x)

Faster than the common normalize function but less accurate.

glm::fastInverseSqrt

GLM_FUNC_DECL vecType< T, P > fastInverseSqrt(vecType< T, P > const &x)

Faster than the common inversesqrt function but less accurate.

glm

Definition: _noise.hpp:11

glm::fastSqrt

GLM_FUNC_DECL vecType< T, P > fastSqrt(vecType< T, P > const &x)

Faster than the common sqrt function but less accurate.

glm::fastLength

GLM_FUNC_DECL T fastLength(vecType< T, P > const &x)

Faster than the common length function but less accurate.
