<hr><a name="_details"></a><h2>Detailed Description</h2>
This is actually the same class as <a class="el" href="classcsPoly3D.html" title="The following class represents a general 3D polygon.">csPoly3D</a>.
<p>
But it has been renamed to make it clear that it is for other uses. It also adds some functionality specific to that use. In particular this class is more used to hold an unordered collection of 3D vectors.
