Has anyone extended the webl\_lines\_fat example to allow for a perspective/depth modified fat line? That is, I want lines that are thick in world space, but as they recede into the distance they scale accordingly.

Here’s the example I’m referring to:  
[https://threejs.org/examples/webgl\_lines\_fat.html](https://threejs.org/examples/webgl_lines_fat.html)

I’m guessing I’d have to modify something within [https://github.com/mrdoob/three.js/blob/22ed6755399fa180ede84bf18ff6cea0ad66f6c0/examples/jsm/lines/LineMaterial.js](https://github.com/mrdoob/three.js/blob/22ed6755399fa180ede84bf18ff6cea0ad66f6c0/examples/jsm/lines/LineMaterial.js)

Ahead of stumbling around this shader code myself, I was curious if anyone’s already been successful with this before?

I guess you are looking for something like this, right?

Exactly that 🙂 THANK YOU!
