How to write a wireframe shader

Did someone already write a 3d shader that display a mesh in wireframe? I’m kind of clueless with shaders.

I just tried to do that with Godot’s node-based shader editor and the text-based editor.

and failed.

and found this article… waiting for 3.0 may be an alternative.

Indeed. It looks like reduz is only focusing on 2d now.
By the way I’m curious about your attempt. Would you mind to share your shader’s code?

I just made the mesh faces invisible and transparent.
