Glowing Shader for GLSL noob?

The goal is to get my 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.
√ documentation
√ the google.

i posted a patch in this topic that performs a bloom shader on opengl geometry.
should do the trick.
