REFLECT(3G) [FIXME: manual] REFLECT(3G)
NAME
reflect - calculate the reflection direction for an incident vector
DECLARATION
genType reflect(genType I, genType N);
genDType reflect(genDType I, genDType N);
PARAMETERS
I
Specifies the incident vector.
N
Specifies the normal vector.
DESCRIPTION
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.
