glm

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...
