Earlier versions of POV-Ray used a feature called <code>halo</code> to simulate fine particles such as smoke,
steam, fog, or flames. The <code> halo</code> statement was part of the <code>texture</code> statement. This feature
has been discontinued and replaced by the <code>interior</code> and <code>media</code> statements which are object
modifiers outside the <code> texture</code> statement.
</p>
<p>
See "<a href="s_128.html#s03_06_01_01">Why are Interior and Media Necessary?</a>" for a detailed
explanation on the reasons for the change. See "<a href="#l144">Media</a>" for details on <code>media</code>.
