==It is Flares!== Technically it's "flares" A lens flare is usually an effect of light passing through a lens of some sort and creating a rainbow or colored bloom effect.. Flares of light are the type seen in foggy , or dusty areas,. or where the air particle content is high or there is alot of water vapor /humidity in the air.. the light cast will create a physical shadow or projectiion of what it's passing over onto other objects. This is from the perspective of a professional graphic artist --o0paradox0o 08:55 am, 28 Sep 2006 (EST)

Okay, but I'm thinking it must be both flares and glows, because sprites are not only used for the effects you describe, but also for normal shining of bulbs - it is used to blind the player when he looks directly at a bulb - but however they are called "glows" in the browser, so that's probably the head category. I'll change it accordingly. --Andreasen 06:09, 28 Sep 2006 (PDT)
Lens Flare, Glare, Bloom, etc are caused by internal reflections (etc) in the Lens system itself. These are therefore rightly simulated in the Player Viewport (see HDR). (Atmospheric) Scattering is caused entirely by reflective particles (fog, dust, etc) or translucent materials in the Light's path, and is therefore (rightly) simulated by World sprites, etc. IMO Halos would be a better word for glow sprites etc. --Beeswax 13:07, 13 Apr 2008 (PDT)
