<hr><a name="_details"></a><h2>Detailed Description</h2>
A class which holds vertices and connectivity information for a triangle mesh.
<p>
This is a general vertices structure but it is mostly useful for LOD generation since every vertex contains information which helps selecting the best vertices for collapsing.
