I'm looking to create a shader to apply a glowing halo around a logo, something similar to the post corona shader in the nVidia FX Composer library. Can anyone point me to something that does this?

Thanks!

Valve's "Improved Alpha-Tested Magnification for Vector Textures and Special Effects" paper gives a good technique for doing a glow effect on 2D objects (and outlines, drop shadows, etc). It does require writing a tool to pre-process your 2D shape though.

Is this their Distance Field thing? Because if so, you can get that over here (in XNA 3.1, feel free to update [smile])

A drop in solution would be nice, since I have to deliver Saturday, but thanks for the link. Looks like interesting reading if nothing else.

I have to ask, what's not drop-in about the XNA project I linked to? It seemed fairly complete and selfcontained to me? [smile]

I didn't see your sample when I posted. It's not quite what I'm looking for though. I'm looking for something more like this
