| 9 | <code class="function">glFogCoord</code> specifies the fog coordinate that is associated with each vertex and | |
| 10 | the current raster position. The value specified is interpolated and used | |
| 11 | in computing the fog color (see <a class="citerefentry" href="glFog.xml"><span class="citerefentry"><span class="refentrytitle">glFog</span></span></a>). | |
| 12 | </p></div><div class="refsect1" lang="en" xml:lang="en"><a id="notes"></a><h2>Notes</h2><p> | |
| 13 | <code class="function">glFogCoord</code> is available only if the GL version is 1.4 or greater. | |
| 14 | </p><p> | |
| 15 | The current fog coordinate can be updated at any time. In particular, | |
| 16 | <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 | |
