A vehicle controller selects a collision avoidance route corresponding to steering of a vehicle by a driver, to control the vehicle so that the vehicle runs based on the selected collision avoidance route. The coordinate measuring apparatus has a device that holds a CMM adapter plate in a way that simulates the locating points on the electromagnetic device in the CMM. Part or all of the wires is sealed with a second mixture including a filler and a resin. The micropolygons may be defined by the intersection of the geometric primitive and boundaries projected from specified screen space regions.
