The Research On The Modification Of Rational Bezier Curves

This thesis mainly studies the change of method about rational Bezier curve. The first through the single control point and right factor and the simultaneous change their approach to change the shape of rational Bezier curve.the second add restrictive condition to change the shape of rational Bezier curve.The first chapter introduces the computational geometry、CAGD and CG background and development.The second chapter introduces the definition of rational Bezier curve and the nature of the curve.the definition of the right factor and geometric meaning.The third chapter introduces the scholars about rational Bezier curve several methods of mosification.In the fourth chapter introduces the problem of the curve and to solve it.
