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);
}
