  • Publication number: 20100177110
    Abstract: A method of fast coloring a polygon for calculating areas of figures, the method comprising steps of resetting record values of all coordinate points to zero in the memory space; inputting the coordinate value of the ordered nodes defining the polygon into the memory space; connecting the nodes according to a predetermined order to determine connection points between the nodes; assigning a record value of each of the nodes as a flag value or a line value; assigning a record value of each of the connection points as a flag value or a line value; and calculating the area of the polygon by processing record values of the coordinate points in the memory space according to the record values of the nodes and the record values of the connection points. The method of fast coloring a polygon of the present invention is implemented with ordinary instead of complicated hardware configurations.
