glm::fastLength
GLM_FUNC_DECL T fastLength(vec< L, T, Q > const &x)
Faster than the common length function but less accurate.
glm::fastDistance
GLM_FUNC_DECL T fastDistance(vec< L, T, Q > const &x, vec< L, T, Q > const &y)
Faster than the common distance function but less accurate.
glm::fastInverseSqrt
GLM_FUNC_DECL vec< L, T, Q > fastInverseSqrt(vec< L, T, Q > const &x)
Faster than the common inversesqrt function but less accurate.
glm::fastNormalize
GLM_FUNC_DECL vec< L, T, Q > fastNormalize(vec< L, T, Q > const &x)
Faster than the common normalize function but less accurate.
glm::fastSqrt
GLM_FUNC_DECL vec< L, T, Q > fastSqrt(vec< L, T, Q > const &x)
Faster than the common sqrt function but less accurate.
