| Abstract: | By using the projective geometry,some schemes for generating rational curves from pencil of lines are investigated in this paper.The constructions of rational curves depend on the pencil of lines which may be blended in two or more straight lines.can be chosen Bernstein polynomials,B splines or many knot cardinal splines. |

| Keywords: | pencil of lines rational curve bernstein polynomial spline |
