Volumetric Fog!?

Hello, I have just started to mess around with fog. What I’d like to know is how to do volumetric fog (like fogging around a cube, with a starting and ending point in 3D space)…

Has this got to do with glFog*() functions, or is it related to Transparency values (fog depth determining transparency of fog surface)??

I would appreciate any help

-Thanks

There’s a pretty good thread about volumetric fog in the old forum.
