The_Lionhearted Posted April 14, 2007 Share Posted April 14, 2007 Something I've been wondering about for a while: :? Could someone explain to me when it is good to disable anti-aliasing ( :AntiAliasingOff: ) and when it's good to keep it on? Some tutorials say to disable aa and some don't, so...I know what aa is but was wondering if I could get the experts to explain how to use it well. Thanks in advance. 8) Quote My Gallery Link to comment Share on other sites More sharing options...
FireFly Posted April 14, 2007 Share Posted April 14, 2007 Well I'm no expert and I'm not going to tell you how to use it, but I always keep it on for everything. I just like having nice, clean, smooth images without jagged edges. It's just me. I'm sure there are many things that aa should be turned off for but I don't (not now anyway).

Illnab1024 Posted April 14, 2007 Share Posted April 14, 2007 Generally, drawing horizontal & vertical lines (and other things involving... horizontal and vertical lines) is a good place to disable anti-aliasing. Quote ~~ Link to comment Share on other sites More sharing options...
sagedavis Posted April 14, 2007 Share Posted April 14, 2007 I haven't found AA to really play as much of an affect so far. It sure plays a big role in 3d rendering, but so far, in 2d, as long as the image isn't mondo huge, I haven't seen any noticable difference. Of course, I could just be blind. Hey, it can happen.

BmB23 Posted April 14, 2007 Share Posted April 14, 2007 Illnab, why? It doesn't show anyways in those cases. Sagedavis, AA does infact help. Everything becomes more smooth, and looks better... unless you are running 800 x 600, in wich case an unblurry image is unavoidable. Now if only the selection tools would have AA too.

Helio Posted April 14, 2007 Share Posted April 14, 2007 I'll answer for Illnab: Anti-aliasing on perfectly horizontal and vertical lines adds blending on both tips, and if the brush size number is even, it will add shading lines on both sides. This is good in some cases, but sometimes a very sharp line is needed. Quote v An excellent open–source strategy game—highly recommended.  "I wish I had never been born," she said.

The_Lionhearted Posted April 15, 2007 Author Share Posted April 15, 2007 Thanks for the feedback...let me see if I'm getting this straight. When you need to have things straight up/down/left/right, disabling the AA is good because it makes the tips of the line sharper and less rounded? Also, what do you mean by shading lines? Do you mean (on a black line) having a pixel of grey running along the sides? Quote My Gallery Link to comment Share on other sites More sharing options...
MadJik Posted April 15, 2007 Share Posted April 15, 2007 Test it you'll see: Anti alias on, draw in column in the left side base or radius 40px a square a circle a triangle a polygone Anti alias OFF, draw in column in the RIGHT side base or radius 40px a square a circle a triangle a polygone ZOOM in 1600px and take the conclusion!
