REFLECT(3G) [FIXME: manual] REFLECT(3G)

reflect - calculate the reflection direction for an incident vector

genType reflect(genType I, genType N);

genDType reflect(genDType I, genDType N);

I

Specifies the incident vector.

N

Specifies the normal vector.

For a given incident vector I and surface normal N reflect returns the reflection direction calculated as I - 2.0 * dot(N, I) * N.

N should be normalized in order to achieve the desired result.
