Functions |
| template<typename T > |
| detail::tvec3< T > | cross (detail::tvec3< T > const &x, detail::tvec3< T > const &y) |
| | Returns the cross product of x and y.
|
| template<typename genType > |
| genType::value_type | distance (genType const &p0, genType const &p1) |
| | Returns the distance betwwen p0 and p1, i.e., length(p0 - p1).
|
| template<typename genType > |
| genType::value_type | dot (genType const &x, genType const &y) |
| | Returns the dot product of x and y, i.e., result = x * y.
|
| template<typename genType > |
| genType | faceforward (genType const &N, genType const &I, genType const &Nref) |
| | If dot(Nref, I) < 0.0, return N, otherwise, return -N.
|
| template<typename genType > |
| genType::value_type | length (genType const &x) |
| | Returns the length of x, i.e., sqrt(x * x).
|
| template<typename genType > |
| genType | normalize (genType const &x) |
| | Returns a vector in the same direction as x but with length of 1.
|
| template<typename genType > |
| genType | 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.
|
| template<typename genType > |
| genType | refract (genType const &I, genType const &N, typename genType::value_type const &eta) |
| | For the incident vector I and surface normal N, and the ratio of indices of refraction eta, return the refraction vector.
