A network communication structure, system and method are disclosed in the invention. The fixation device includes a housing with a housing tool end and a housing template end, a seat located on the housing tool end for coupling with the rotating machine tool, and a clamping mechanism disposed at least partially at the housing template end for coupling with at least one locating pin. The socket assembly comprises a socket adapted to receive the light assembly and a bypass mechanism having a first position and a second position. The compressed stencil buffer is utilized with a compressed stencil buffer cache to perform a stencil shadow volume operation more efficiently than present methods.
