Bloom 2/2 � Recombine (with increasing resolution): E’= blur(E,b5) D’= blur(D,b4)+E’ C’= blur(C,b3)+D’ B’= blur(B,b2)+C’ A’= blur(A,b1)+B’ � Blurring while up sampling � Improves quality � Barely affects blur radius blur(blur(X,a),b) ~= blur(X,max(a,b)) � Combine with dirt texture Advances in Real-Time Rendering in 3D Graphics and Games Course
