<a name="cogl-intro"></a>About Cogl</h2></div></div></div>
<p>Cogl is a modern 3D graphics API with associated utility
APIs designed to expose the features of 3D graphics hardware
using a more object oriented design than OpenGL. The library has
primarily been driven by the practical needs of Clutter but it
is not tied to any one toolkit or even constrained to developing
UI toolkits.</p>
