<pageclass subcaption="C++ Function"></pageclass>

This C++ namespace function is a helper function for [[CAdditionalVertexStreamManager]].
It gets 64 bit key for a triangle by using the ordered vertex indices.

It can be found in '''Client/Client Core/Sources/CAdditionalVertexStreamManager.cpp''' in Visual Studio.

==Required Arguments==
*'''a:''' To be defined.
*'''b:''' To be defined.
*'''c:''' To be defined.

==Returns==
Returns a long long 64 bit key for a triangle.

==Code==
<syntaxhighlight lang="c++">
long long getTriKey ( WORD a, WORD b, WORD c )
{
WORD tmp;
if ( b < a ) { tmp = b; b = a; a = tmp; }
if ( c < b ) { tmp = c; c = b; b = tmp; }
if ( b < a ) { tmp = b; b = a; a = tmp; }
return ( ((long long)a) << 32 ) | ( ((long long)b) << 16 ) | ((long long)c);
