GLM_FUNC_DECL vecType< T, P > | refract (vecType< T, P > const &I, vecType< T, P > const &N, T eta) |
These operate on vectors as vectors, not component-wise.
GLM_FUNC_DECL tvec3<T, P> glm::cross | ( | tvec3< T, P > const & | x, |
tvec3< T, P > const & | y | ||
) |
Returns the cross product of x and y.
valType | Floating-point scalar types. |
GLM_FUNC_DECL T glm::distance | ( | vecType< T, P > const & | p0, |
vecType< T, P > const & | p1 | ||
) |
Returns the distance betwwen p0 and p1, i.e., length(p0 - p1).
genType | Floating-point vector types. |
GLM_FUNC_DECL T glm::dot | ( | vecType< T, P > const & | x, |
vecType< T, P > const & | y | ||
) |
Returns the dot product of x and y, i.e., result = x * y.
genType | Floating-point vector types. |
GLM_FUNC_DECL vecType<T, P> glm::faceforward | ( | vecType< T, P > const & | N, |
vecType< T, P > const & | I, | ||
vecType< T, P > const & | Nref | ||
) |
If dot(Nref, I) < 0.0, return N, otherwise, return -N.
genType | Floating-point vector types. |
GLM_FUNC_DECL T glm::length | ( | vecType< T, P > const & | x | ) |
Returns the length of x, i.e., sqrt(x * x).
genType | Floating-point vector types. |
GLM_FUNC_DECL vecType<T, P> glm::normalize | ( | vecType< T, P > const & | x | ) |
Returns a vector in the same direction as x but with length of 1.
According to issue 10 GLSL 1.10 specification, if length(x) == 0 then result is undefined and generate an error.
GLM_FUNC_DECL genType glm::reflect | ( | genType const & | I, |
genType const & | N | ||
) |
For the incident vector I and surface orientation N, returns the reflection direction : result = I - 2.0 * dot(N, I) * N.
genType | Floating-point vector types. |
GLM_FUNC_DECL vecType<T, P> glm::refract | ( | vecType< T, P > const & | I, |
vecType< T, P > const & | N, | ||
T | eta | ||
) |
For the incident vector I and surface normal N, and the ratio of indices of refraction eta, return the refraction vector.
genType | Floating-point vector types. |
