| Abstract: | An algorithm to fill a closed B-spline curve was given. The way of the algorithm is similar with the scan-filling algorithm of polygons. Three methods were used in the filling algorithm. They are the method to get the intersecting points of a horizontal line and a B-spline curve, the method to judge a horizon line of B-spline curves, and the method to get extremum points of a B-spline curve. The algorithm has a high effect and a broad applied value. |
