Hello to all!
Well, I was looking at a topic here:
http://www.renderosity.com/mod/forumpro/showthread.php?message_id=4126890&ebot;_calc_page#message_4126890
and this caused me a question that was not answered there
I wanted to see the suggestions here

I think he is saying that he doesn't use anti-aliasing for 1920 x 1080 because that is the Master which is then downsized for distribution, and so the benefits of anti-aliasing will be lost anyway.
What Cayman said. Anti-aliasing does nothing going smaller, or so I believe.
EXCEPTION!
If you are NOT reducing the resolution of your image, antialiasing DOES matter. If that 1920 x 1080 does not have antialiasing, you will have a very jagged, odd-looking render when viewed at 1920x1080.
In addition, geometry or transmaps that end up smaller than a pixel will look VERY odd without anti-aliasing. The picture below explains what I mean. This can affect things like hair, wires on a robot, ribbing on the grip of a tool, and the like. It goes from a single line to a series of jagged dots that may or may not end and restart in the middle (the green represents the item in question).
So "antialiasing does nothing" is not exactly true, especially if hair or detailed surfaces are involved. Shrink those grids down to 3-4 pixels across and it's easier to see what I mean.
@Cayman and Paradigm67
Hmm, so in the case of an animation in poser and vue in 1920 x 1080 can be disabled AA, even for dvd / blue ray and it will still be commercially quality?
Hi Valandar,
When I translate to Portuguese of Brazil, what you said up there, I get confused:
The first part seems to say that there is no problem, if not for reducing the image;
The second half seems to say that there are problems if the render view in 1920x 1080
I do not think in reducing the size, and even I'm afraid that when you finish the project, the full HD 1920 x 1080 is already exceeded by another value greater ...

Thin items render bad withithout Anti-Aliasing.
Thin items render correctly WITH Anti-Aliasing.
I think that was my most important point, and should translate well, and my picture shows why it is so.
Thin items are like wires, hair, thin patterns, and so on.

Oops, now I understand!
Thus, taking, or not to render, I will not leave the ant - aliasing outside the renders not.
Thank you for explanation.
I think he's getting anti-aliasing thanks to his post work anyway
Hmm...?
Even so, the sorts of things I mentioned would not render correctly without the renderer doing at least SOME antialiasing. Ribbed patterns or things like cloth bumps would moire quickly, wires and hair would have jagged missing spots, and the like.

I get it ... Without AA, it's bad ...
With AA, it's good!
Best to go for good, than have to redo all the work later.
thank you
Hmm...?
When software resizes an image (or a video) it has to make some decision about how to handle a diagonal line. This may or may not include the ability to anti alias.
This whole discussion makes me wonder how or where do enable/disable AntiAliasing for a render. For the viewport ok, there is a setting, but does this setting affect the rendered image too?
