Description
The Halo shader is currently only limited to verticies. It would be nice if there were an option to apply the same shader effect to edges rather then verticies.

There have been several instances where I've used the Halo for effects like neon light, but it's a real pain because you have to split edges up many many times to get the desired effect, and even then you have problems with the physical scale of the object, and different densities of the verticies along the subdivided edges.

Would probably mean disabling some of the options like "star" with this option enabled.

Interesting idea but I wonder if this is desirable. If it wouldn't be smarter to create something more along the lines of a glow shader (search glow on this forum) since most uses of halos along the lines that you are refering to are simply workarounds for a true glow effect.
So currently I'm not voting for it yet but my tendency is towards no. I think the time should better be invested in a true glow shader.

I agree with above, It doesn't help that most halo textures rely on point sources..

How were you expecting it to work with an edge? Mayve the scaling of a halo texture between two points...?

I think a true glow shader would me much better. What media were you hoping to present, still, annimation or game?
