GLM_FUNC_DECL GLM_CONSTEXPR T | dot (vec< L, T, Q > const &x, vec< L, T, Q > const &y) |
Returns the dot product of x and y, i.e., result = x * y. More... | |
template<length_t L, typename T , qualifier Q> | |
GLM_FUNC_DECL vec< L, T, Q > | faceforward (vec< L, T, Q > const &N, vec< L, T, Q > const &I, vec< L, T, Q > const &Nref) |
If dot(Nref, I) < 0.0, return N, otherwise, return -N. More... | |
template<length_t L, typename T , qualifier Q> | |
GLM_FUNC_DECL T | length (vec< L, T, Q > const &x) |

template<length_t L, typename T , qualifier Q> | |
GLM_FUNC_DECL vec< L, T, Q > | normalize (vec< L, T, Q > const &x) |
Returns a vector in the same direction as x but with length of 1. More... | |
template<length_t L, typename T , qualifier Q> | |
GLM_FUNC_DECL vec< L, T, Q > | reflect (vec< L, T, Q > const &I, vec< L, T, Q > const &N) |
For the incident vector I and surface orientation N, returns the reflection direction : result = I - 2.0 * dot(N, I) * N. More... | |
template<length_t L, typename T , qualifier Q> | |
GLM_FUNC_DECL vec< L, T, Q > | refract (vec< L, T, Q > const &I, vec< L, T, Q > const &N, T eta) |
