<para>
|
|
<function>glFogCoord</function> specifies the fog coordinate that is associated with each vertex and
|
|
the current raster position. The value specified is interpolated and used
|
|
in computing the fog color (see <citerefentry><refentrytitle>glFog</refentrytitle></citerefentry>).

<para>

The current fog coordinate can be updated at any time. In particular,
|

<function>glFogCoord</function> can be called between a call to <citerefentry><refentrytitle>glBegin</refentrytitle></citerefentry> and the corresponding
|
|
call to <citerefentry><refentrytitle>glEnd</refentrytitle></citerefentry>.
