1. A method for addressing an A-Buffer used to store pixel information, the method comprising: receiving coordinate values that locate a pixel in an image frame and a depth complexity value specifying a depth complexity of a fragment associated with the pixel; computing array coordinates based on the coordinate values and a tile size; determining an array offset based on the array coordinates; computing a tile offset based on the array offset and the depth complexity value; converting the coordinate values to tile coordinates that locate the pixel in a tile; and locating the pixel within the tile based on the tile offset and the tile coordinates.
