My goal is to build an indexed list of triangles from OGR
polygons as inputs to a hardware rasterizer for efficient
rendering. I see RFC 64 was implemented a few years ago but
the documentation warns "not yet implemented". </div>

<p>-->where exactly do you see this mentioned?</p>
<p><br>
</p>
<p>Anyway, tesselation as triangles wasn't in the scope of the RFC</p>
<p><br>
</p>
<p>But you might want to use OGR_G_DelaunayTriangulation()<br>

Is this functionality available? If not, are viewers like QGIS
manually building an index list themselves (or perhaps they
use old fixed function APIs)?<br>
