- <code class="function">glFogCoord</code> 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 <a class="citerefentry" href="glFog.xml"><span class="citerefentry"><span class="refentrytitle">glFog</span></span></a>).
- </p></div><div class="refsect1" lang="en" xml:lang="en"><a id="notes"></a><h2>Notes</h2><p>
- <code class="function">glFogCoord</code> is available only if the GL version is 1.4 or greater.
- </p><p>
- The current fog coordinate can be updated at any time. In particular,
- <code class="function">glFogCoord</code> can be called between a call to <a class="citerefentry" href="glBegin.xml"><span class="citerefentry"><span class="refentrytitle">glBegin</span></span></a> and the corresponding
- call to <a class="citerefentry" href="glEnd.xml"><span class="citerefentry"><span class="refentrytitle">glEnd</span></span></a>.
