isn’t the alphaB is the exact same idea with a? So this two methods should be the same?
I've been having a misunderstanding that "If A have alpha 0.5 and B have alpha 0.5, then there is no difference between A over B and B over A".
After this lecture and implementing alpha compositing in Ass 1, I see the difference.
