Calculate the cross product between two vectors (not taking into account the w ordinate).
CL_Vec4<Type>& CL_Vec4< Type >::cross3( const CL_Vec4 < Type > & vector); static CL_Vec4<Type> CL_Vec4< Type >::cross3( const CL_Vec4 < Type > & vector1, const CL_Vec4 < Type > & vector2);
Detailed description:
\vector1 = The first vector \vector2 = The second vector
