What is the best approach to render lines over a mesh?

Hi, I was trying to recreate some Three.js projects into Unity as a training exercise.

Basically: https://github.com/spite/THREE.MeshLine

My first aproach was using particles (VFX) with trails on a SDF surface, but I gues there might me another approach:
- thought on Vertex Shaders
- some scripting to render multiple lines with LineRenderer

Look forward to receiving advices/documentation/projects examples. Thanks!

 

some ideas:
- wireframe shaders https://assetstore.unity.com/?q=wireframe shader&orderBy=1 (there's many free ones in forums/github too)
- gl.lines https://docs.unity3d.com/ScriptReference/GL.LINES.html
- linerenderer https://docs.unity3d.com/ScriptReference/LineRenderer.html
- compute shaders https://github.com/keijiro/Swarm *check his other repositories too for more newer ones

 

They look like they have a bit of thickness to them.

I would just do that by converting the line into a Unity mesh. They could be done as a strip of triangles or a cylinder tube.

From the look of the image they might be tubes with a flat shader.
