I never heard of this AA
thing I don't even need AA but seriously
guys I'm not talking about Alcoholics Anonymous I'm talking about
anti-aliasing which refers to the technology that removes jaggies or the
staircase effect from your video games in real time making them appear smoother
so where the heck do jaggies come from well the images on your computer screen
are made up of tiny squares called pixels whereas real objects have rounded
Corners so what happens is when you take a bunch of squares and line them up you
end up with a nice straight line that looks perfect but then what happens if
you try to draw a diagonal line that's where the squares end up corner to
corner and you end up with that staircase effect that looks quite
unappealing now there are a wide variety of different kinds of anti-aliasing the
most basic being msaa or multi- sample anti-aliasing and some more advanced
newer ones like FXAA which is a faster
more approximate style of anti-aliasing from NVIDIA but they all work in
fundamentally the same way that is to say that they take the missing data in
that line and they go okay well there's there's a gap here but we're going to
take samples all around it and try to fill in the approximate data that should
be there in order to make the image look more pleasing to the user I call
anti-aliasing fake resolution you're always better off to increase the
resolution to get a more clear image hence something like Apple's Retina
Display where rather than using using anti-aliasing tricks they actually are
just squeezing more pixels into the point where your eye can't even tell
that it's a square block anymore but if you don't have that option anti-aliasing
is a way of making it look smoother and higher resolution without actually
upgrading the display device that you're using thank you for checking out this
explanation on Techquickie for anti-aliasing and as always don't forget
