Hello @asymmetric,

There is a tutorial about the renderers here:  
[https://processing.org/tutorials/rendering](https://processing.org/tutorials/rendering)

I have a very simple pixel viewer here:

> Hello, A very simple pixel viewer that I use to zoom in on sketch. Try different renderers, smooth() values, etc. I even tried odd and even. No pun intended! Some code for you to experiment with: // Pixel Viewer // v1.0.0 // GLV 2022-08-06 PImage img; boolean toggle; int oddeven, count, choice; void setup() { //size(650, 600); size(650, 600, P2D); //size(650, 600, P3D); background(255); //smooth(4); // Default is 2 noSmooth(); //strokeWeight(1); } …

Replace the shapes with a line and experiment a little.

You are also limited by the pixel density of your device; you can’t do better than a single pixel and smoothing will just give the appearance of a “smoother” line. Try the pixel viewer to see this.
