Emitting media glows, rather than absorbing or scattering light. If
radiosity is on and "media on" is used, it will take media into account
when computing radiosity lighting, and emitting media (or brightly lit
scattering media) will cast a glow on nearby surfaces. (Media doesn't
take radiosity into account, though...a bright surface won't illuminate
nearby scattering media. That would be very slow, though it may be
possible to make it reasonably fast with something like photon mapping.)
