Earlier versions of POV-Ray used a feature called halo to
simulate fine particles such as smoke, steam, fog, or flames. The
halo statement was part of the texture statement. This
feature has been discontinued and replaced by the interior and
media statements which are object modifiers outside the
texture statement.
See "Why are Interior and Media Necessary?"
for a detailed explanation on the reasons for the change. See "Media"
for details on media.
