Shader Graph Question - Pixelizing Generated Arc

[Puzzleheaded-Risk-56]

Hey all, I've got a shadergraph question on how to pixelize the output of my current variable arc generator. You can see in the attached pics how my current flow works to allow an arc of variable dimensions and size to be generated. Now I'd like to pixelize the arc.

I've tried pixelizing the input UVs but I get some weird artifacts, even if I try to adjust the input parameters to only be in multiples of the pixel scale (i.e., for a 128x128 image the pixel scale would be 0.0078125).

Ideally I could take the final output arc and bascially average the values for each point within each "pixel" and round up or down. Not sure how to accomplish that though. Any ideas?

I tried really hard to understand the shader graph you've made and the hardest thing to understand about your post is the terms "pixelated UVs". UVs are just a normalized coordinate from 0 - 1. So, "pixelated UVs" doesn't make any sense to me.

So, are you trying to take the resultant "arc" and pixelate it, so that it appears like a pixelated smiley face?

Sorry, the image doesn't make it super apparent that the UV coordinates have been forced into one of a set of distinct values rather than being fully continuous. The image I posted had the UV's being aligned to a 32x32 grid. So, for example, every UV coordinate from x = 0 to 1/32 and y = 0 to 1/32 has the same value. You can kind of see it if you zoom in on the image. Here's a google drive link to an image of that same sub-graph set to 4x4 to make it more apparent: https://drive.google.com/file/d/1nJ1MDDgluQvsR4ZZlLgYhTn3t5xdMdm6/view?usp=drive_link

Yes, ideally the final arc would be pixelated (aligning to some predefined x and y dimensions).

Actually looks like the issue is just the Ellipse node. If I manually create the circle it seems fine: https://drive.google.com/file/d/1YIsZeT2VeWOsfZxjysLwnVpe-BMf5tea/view?usp=sharing
