reflect — calculate the reflection direction for an incident vector
genType reflect(
genType I, genType N)
;
genDType reflect(
genDType I, genDType N)
;
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.
