Glossy ComputationincomingWhen computing glossy reflection, let Iin, be the intensity of the itlight ray, let dį be its incoming direction, and let reflected(Iin,i, d¿) be theintensity of that light ray after glossy reflection.Averaging over the reflected light from all incoming light rays, we could computeIout-NNi=1reflected(Iin,i, di) (Method 1)or we could average over the intensities and over the directions first, to computeIout = reflected(Ni=1lin,i,NNi=1(d;) (Method 2). For efficient computer implementations of each method, which statement below istrue?The two methods produce the same answer. Method 1 is more efficient.The two methods produce the same answer.
