Definition: _noise.hpp:11
glm::dot
GLM_FUNC_DECL T dot(vecType< T, P > const &x, vecType< T, P > const &y)
Returns the dot product of x and y, i.e., result = x * y.
glm::cross
GLM_FUNC_DECL tvec3< T, P > cross(tvec3< T, P > const &x, tvec3< T, P > const &y)
Returns the cross product of x and y.
glm::reflect
GLM_FUNC_DECL genType reflect(genType const &I, genType const &N)
For the incident vector I and surface orientation N, returns the reflection direction : result = I - ...
glm::faceforward
GLM_FUNC_DECL vecType< T, P > 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.
glm::normalize
GLM_FUNC_DECL vecType< T, P > normalize(vecType< T, P > const &x)
Returns a vector in the same direction as x but with length of 1.
glm::distance
GLM_FUNC_DECL T distance(vecType< T, P > const &p0, vecType< T, P > const &p1)
Returns the distance betwwen p0 and p1, i.e., length(p0 - p1).
glm::length
GLM_FUNC_DECL T length(vecType< T, P > const &x)
Returns the length of x, i.e., sqrt(x * x).
glm::refract
GLM_FUNC_DECL vecType< T, P > 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...
