A system and method for animating a character with activation-driven muscle deformation. The steer-by-wire system includes a driver interface system, a road wheel actuator system, and a controller for monitoring and implementing the preferred control strategy. Based on a forward voltage Vf produced at this time, an output voltage VA of a DC-DC converter 4 is controlled and provided as a drive voltage VA for the light emitting panel. Next, a set of multivariable equations are generated for each evaluation point, each equation representing influence of neighboring features on a mask. Additionally, the irregular bumps have a plurality of integral probed portions far away the line, top surfaces of which are expanded such that probed points can be defined on the probed portions for staggered probing.
