  You can use a texture with a circular blend pattern for alpha that fades out from alpha=1 in the center to alpha=0 at the edges. If you map this across a quad, and assign a diffuse color, you get a colored particle. A more complex quad, perhaps as a triangle fan, can allow you to do more complex coloration, such as one color at the center blending into another color at the edges. The alpha component of the texture causes the particle to fade to transparent. GolemBlender--The Gimp--Python--Lua--SDLNethack--Crawl--ADOM--Angband--Dungeondweller
