<hr><a name="_details"></a><h2>Detailed Description</h2>
This class reduces the complexity of the geometry it is given.
<p>
This class is dedicated to reducing the number of triangles in a given mesh taking into account seams in both geometry and texture co-ordinates and meshes which have multiple frames. <dl compact><dt><b></b></dt><dd>The primary use for this is generating LOD versions of <a class="el" href="classOgre_1_1Mesh.html">Mesh</a> objects, but it can be used by any geometry provider. The only limitation at the moment is that the provider uses a common vertex buffer for all LODs and one index buffer per LOD. Therefore at the moment this class can only handle indexed geometry. </dd></dl>
<dl compact><dt><b></b></dt><dd>NB the interface of this class will certainly change when compiled vertex buffers are supported. </dd></dl>
