Filtering flickering on screen

[Ats]

if you want your cos(x) functions to stop aliasing (flickering) on the screen, you need to filter them. If w=pixel size, replace cos(x) by
(1/w)∫cos(t)dt, t ∈ (x-½w, x+½w) = cos(x)·sin(½w)/(½w)

I just read that article and find the rendering very smooth. Is it possible to achieve something like this in ZGE using shaders?

Hi Ats,

Sure, you can just ( pretty much ) copy-paste the fragment shader. Thing is though, that this is a technique useful with runtime procedural textures. So unless that's what you're doing there are better & faster alternatives available.

Oh. All right then. I'll try it for the flickering stars in the background of Omeganaut.
But maybe a simpler anti aliasing filter would be better to smooth everything.
