Question How to draw lines with efficiency and without pixelation or aliasing?

Hello Worldbuilders

Has anyone discovered how to draw lines with efficiency and without pixelation?

The pixelation problem occurs when using Unity's LineRender components - which has a nice simple interface. However I've yet to be able to get it to render nice, crisp thin lines. Instead it delivers pixelated lines and in some cases not lines at all. For example, this is a 2mm line screenshotted from Game Mode however the same problem occurs with larger widths and in Editor:

When built to device (Quest) - the jagged lines render to the left eye but not the right eye.

Thanks!

I would just use shaders, on large plane, to render many lines like that.
You sdont want to use line renderer, for straight lines.

 

you could try https://github.com/bassmit/lineburst/ I haven't updated it in a while, so let me know if there are any issues

 

I use https://assetstore.unity.com/packages/tools/gui/aline-162772
Which support burst and ecs

 

Thank you all for the suggestions.

What would you use if you were drawing tick intervals (time measures across orders of magnitude - i.e. secs, mins, hrs,... years, centuries, millennia, etc.)?

 

Still shaders
You could use two planes.
One for thinner lines, one for thicker for example.
Or more complex shader.
I did something relevant in 2018

 

I've done a grid like this before. It is indeed just a single shader that draws the whole thing. Basic trick is to use screen space derivatives (ddx and ddy) to make the lines crisp. In this case I've also used the derivatives to blend over powers of 10.
