An air spring for a vehicle suspension includes a resilient spring body that is partially surrounded by a protective cover. The shelf is obtained by shrinking the structure after assembling the panel and the structure. The method of progressively decoding the transmitted, compressed bit stream which has been coded by the coding method, includes dividing the transmitted bit stream into a plurality of coded mesh components, decoding each of the plurality of coded mesh components, and reconstructing a 3-D mesh by synthesizing the plurality of decoded mesh components. A controller is in communication with the sensor and receives the output signal of the sensor. A first stereoscopic image of the game apparatus from the first viewpoint is displayed with a set of pixels configured to be visible to the first viewer.
