Detailed Description
Fast but less accurate implementations of square root based functions.
- Sqrt optimisation based on Newton's method, www.gamedev.net/community/forums/topic.asp?topic id=139956
<glm/gtx/fast_square_root.hpp> need to be included to use these functionalities.
Function Documentation
| GLM_FUNC_DECL 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.
| GLM_FUNC_DECL genType glm::fastInverseSqrt | ( | genType const & | x | ) |
Faster than the common inversesqrt function but less accurate. From GLM_GTX_fast_square_root extension.
| GLM_FUNC_DECL vecType<T, P> glm::fastInverseSqrt | ( | vecType< T, P > const & | x | ) |
Faster than the common inversesqrt function but less accurate. From GLM_GTX_fast_square_root extension.
| GLM_FUNC_DECL genType::value_type glm::fastLength | ( | genType const & | x | ) |
Faster than the common length function but less accurate. From GLM_GTX_fast_square_root extension.
| GLM_FUNC_DECL genType glm::fastNormalize | ( | genType const & | x | ) |
Faster than the common normalize function but less accurate. From GLM_GTX_fast_square_root extension.
| GLM_FUNC_DECL genType glm::fastSqrt | ( | genType const & | x | ) |
Faster than the common sqrt function but less accurate. From GLM_GTX_fast_square_root extension.
