There are no ugly colours, only ugly combinations of colours.

I think there should be one topic about the various pixel art programs. Topics seem to derail quickly whenever MsPaint is involved. :-X

Hehe....subpixel animation. Fun stuff. Moderately hard to pull off successfully though.. but good to know for smooth anims sometimes.  !yus!

It works great with subtle animations, like characters breathing/idling. Also known as animating with colors.

There is another type of sub-pixel art, but that deals with creating art that takes advantage of the RGB layouts of LCD screens to create the illusion of more horizontal detail.

EDIT: Whoops, Ptoing beat me to it. :P

got another query regarding this topic... thnx for the replies btw - even the OT ones.. ;)

So, I understand the technique now - it's pretty much what I thought but you've clarified it for me.

I got a technical question... Sven/Ptoing, in both your examples you demonstrates the anti alias color which the motion is moving from and to... this makes perfect sense... (essentially creating a  kind of motion blur from one pixel to another) however, my query regards masking sprites out -  now obviously, it's easier to demo the technique with the samples you've shown against plain backgrounds... so presumably if one was to create sprites, for say, a GBA game - (not that I think I ever will anymore but for arguments sake)... then presumably one couldn't do the sub-pixel aliasing on the edges that are external of the sprite as this would (I'd imagine) 'fizz' against the various broken colored backgrounds... as you can't dicate what colors your aliasing to - if that makes sense?

So, realistically, in a practicle application, what's the solution? Surely, subpixel anims can really only work within the confined space of the sprites profile/outline...? yes or no...?

If no - how does one manage to reduce (what I visualise) as edge noise - without resorting to alpha maps - which one lo color pixel work you tend not to have access to?

I've not actually tried this as yet so this is pure hypothesis... I may be completely off mark.

Cheers

Yes, only on the inside for sprites unless you have only one colour for the background guess.

Here is an example:


He has some esp at the top of the shoulder.
There are no ugly colours, only ugly combinations of colours.

heres another example:

my link sprites had quite a bit of subpixel animation, on the sword especially
my decision was, since I had a black outline, to have the outline 'lag' behind the movement of the sword, Im not an expert with subpixel animating, but I think it had good results and at the very least a resolution you could consider

hmmm... yeah I see... this is great chaps... real food for thought...

something I can see I'll need some time experimenting with... I'm now starting to have ideas of where to take this as a technique and using it within my own skillset and adapting it...

hmmm... food for thought indeed...

I wonder...
