Led Wall Shaders

Can anyone convert the Shaders Led Wall for retroarch SLANG?

we already have the ‘bead’ shader in ‘misc’, which does a very similar effect:

Thank you very much, but what would these shaders be? BEAD ? I tried, but it only works if we zoom the image a lot.

it’s easy to modify to make the “beads” bigger. Use this preset instead:

shaders = 2

shader0 = ../stock.slang
scale_type0 = source
scale0 = 0.25
filter_linear0 = false

shader1 = shaders/bead.slang
filter_linear1 = false
scale_type1 = viewport

BEAD_HIGH = 0.45
BEAD_LOW = 0.0
BEAD_SHARP = 50.0

You can change scale0 = 0.25 to whatever size you want (smaller values make bigger beads).

I’m trying it on an old video (not a game), I haven’t managed to get the result I wanted yet, like the LED wall we’re seeing on the streets these days, but I think we’re on the right track. Thanks a lot for the support.

I’m not against the idea of porting that LED wall shader directly, and it seems like it would be a pretty easy port, but I wasn’t able to find any license information in the repo, so in the absence of that, we have to assume it’s not allowed.

Thank you anyway, you were very kind.
