ikz87 / picom-shaders Goto Github PK

When setting up the shaders in my rice, i realized that picom can't apply more than one shader per window, so i had to combine the border shader and the transparency shader to properly work together resulting in code redundancy in the shaders.
So i had this idea, that every shader could be transformed into a simple function that takes the pixel and/or coords and all the configuration options as function arguments.
This would make combining and reordering shaders easy.
Problem is, that glsl doesn't support any #import stuff so the functions would either need to be in the same file, or imported in some other funky way.
Having it in the same file doesn't remove code redundancy, but importing in other funky ways seems complicated as fuck:

What do you think?

Since you seem to be knowing how to code shaders,
do you think it would be possible to overlay stuff over the windows?
Like for example rounded borders, fixing the problem with picoms rounding features cutting of i3 borders.
(i know xborders exist, but doing it with shaders would be way more elegant)
As far as I have understood shaders, it is generally possible, to draw stuff, but since picoms shaders are just "GLSL fragment shaders", I'm not entirely sure.

Here's a list of them: https://github.com/libretro/docs/blob/master/docs/shader/crt.md

CRT Lottes is a really good one and it is pretty accurate.
Crt Royale is not only accurate, it looks really great and its configurable. there's also CRT Mattias, which isn't that accurate but looks "nostalgic", a lot of artifacts, which a lot of people seem to like.
