Graphics - Dithering, Anti-Aliasing, up-scaling, shaders!
Posted: Tue Apr 29, 2014 9:32 am
This thread has been created because of the pastes (recently and over the past many months) requesting / talking about dithering. Let's talk about dithering, anti-aliasing, up-scaling, and in general better graphics!
I made this thread because I don't think people don't know what they mean when they're asking for dithering ... or, I don't understand it, and want to understand it better.
This is current as of FPse 11.113. I'll try to update these initial posts as I get more info. I'm breaking this up into a couple posts because it's too long.

"Note that Dithering and Anti-aliasing are opposite functions. Dithering uses spatial resolution to make up for a lack of colours [makes it appears as if there are colors there that don't exit]. Anti-aliasing uses colours to make up for a lack of spatial resolution [smooths out jagged lines by combining pixel colors around sharp lines, replacing some pixels with pixels of new colors)."
