<h1>NL3D::CPSFaceHelper Class Reference</h1><hr><a name="_details"></a><h2>Detailed Description</h2>
Well, we could have put a method template in <a class="el" href="a03186.html">CPSFace</a>, but some compilers want the definition of the methods in the header, and some compilers don't want friend with function template, so we use a static method template of a friend class instead, which gives us the same result :)
