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
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);
}
