【摘要】 采用射影几何学方法，研究从直线束生成有理曲线的技术方案。有理曲线由直线束确定，直线束由两个或多个直线经调配得出。调配函数可选为伯恩斯坦多项式、Ｂ样条或多结点基数型样条更多还原

【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.更多还原
