glm::fastLength
GLM_FUNC_DECL T fastLength(vecType< T, P > const &x)
Faster than the common length function but less accurate.
glm::fastSqrt
GLM_FUNC_DECL vecType< T, P > fastSqrt(vecType< T, P > const &x)
Faster than the common sqrt function but less accurate.
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.
