A multimode wireless communication device and method for having the device detect a communication access technology is described. When a server, to which an IP address is assignable, is contained in the ad-hoc network, the control unit instructs the new terminal apparatus to access the server. The stent is implanted at a bifurcation so that the main stent section is in the main vessel, and the portal section covers at least a portion of the opening to the side branch vessel. While doing so, the system processes each visible sprite by first compositing the visible sprite into the translucent light map, and then incrementally blurring the resultant translucent light map.
