The goal is to get my jit.gl.sketch lines to glow like this:

That looks like 3 pixel convolution+input for only select portions to me.

It seems to my noob brain that GLShaders only operate on the *faces* of objects but I think what I need is something that operates on the viewport? I think? Maybe?

Can someone point this lost soul in the right directions?

√ So I've read cycling's online tutorial for creating shaders.

very cool. I'll try and implement that technique in my code.
