I've recently implemented a glow effect using a gaussian filter and could not get the full effect I was wanting. I'm curious to know if how certain glow effects are done in WoW. Like this image:
Around the sword is a really nice glow effect. How might this be done? Also, sometimes in WoW you see these glow effects take a life of there own. Like the purple glow in this pic:
Are these accomplished with particle effects? Are there any good resources/tutorials that could help with someone to learn how to do these effects?
