Glow Effect on Edges

How do you make a glow effect on a poly edge in Composite?

I’m new to Blender and I saw this on YouTube, and I don’t think I could do this in Maya.

you need to set you objects onto another layer then apply some composite nodes to that layer

nodes like bright if i remember well
look into wiki page for nodes

i think there is an example there !

or search for video on this effect for blender

happy 2.6

I would probably make that particular effect with beveled curve objects and hooks. If you really wanted to use poly edges, apply a Wire type material with some Emit to your model. In the compositor, a typical way to add glow is to blur the image with a gaussian filter, and Add the blurred image to the original image. You could play around with a Glare filter too, depending on the effect you want. Don’t use brightness/contrast nodes; without masking, they’ll just change the entire image.

I think Andrew Price at blenderguru.com has a nice lightning tutorial that includes similar effects.
