Topic: AA Practice - Circles with science
Posted: 24 January 2011 at 2:10am

I once saw a tutorial that taught me a way of 'scientifically' creating AA.

This is me basically doing the same thing, but I changed the way it's done.

I've only done these two so far:

This is the second circle in progress, each grid contains 100 pixels inside,

allowing me to work out the percentage of how much black I need to stand

against the white.

It hardly seems worth it. When I'm finished doing however many circles

I plan on doing, would it even be submitted to the gallery? I'm curious,

I don't mind if it's not - but I have seen other people posting AA'd line

art practice.

Just did the third circle, I'd rather do this stuff by eye, seriously!

So I won't be doing anymore, that's the end of that chapter.

Definetely not sending into the gallery, just practice - and that's

all it shall be.

Peace!

Interesting, seen some similar stuff over on Pixelation before. Now try hollow circles ;D

Another practice I did with the same 'trick' I used here, but again - I've changed the way I do it (for convenience's sake).

I like the look of pixel art zoomed in way more then zoomed out.

Yeah, that's basically how you algorithmically scale an image down with "interpolation" (wrote one for brush-scaling in Grafx2 the other day). So you don't really need to calculate it yourself...you could just scale the image in any gfx-program and study it. But it's nice to see someone looking at things from scientific perspective...it will help you understand how colors etc. work. Exploring is fun! :)

@Elk,

I think that circle is insanely good for pixel art - it comes off with the

impression that it looks painted! It's really sweet. I will definitely study

it later. :-)

@DawnBringer,

My brother and I worked the formula out, it's relatively simple. Sometimes

I'd mix a whole palette of 'AA colours' with the intention of purely blending

edges of colours. I never use the formula to make colours though.

I've also seen your works, about your palette and how you scientifically

created it for the palette competition, which is now being used in the iso

collaboration, I thought that was really cool when I looked at the science

behind it (images you posted). Yay for science!

More AA practice. It's the creeper from Minecraft. Wasn't doing anything

special with the colours. It's hard to make AA work when everything was

so packed together.

My next one will be a little more difficult, as I'll be trying to AA a line

inbetween two colours. I suppose you could call this a proper test

because I chose a nice earthy brown for an outline, a lush skin tone

and a soft blue for the background sky!

I'll come back and post the finished product when it's done.

edit 1:
I'm half way through it and I don't know why but I was stupid enough

to do it with the old 'exact' method. I'll still see it through, but this really

is stupid. This is the last time I'm doing it like this LOL. It won't even look

good.

edit 2:
Well there you have it folks. I'm very satisfied with the outcome.
