The Research On The Modification Of NURBS Curves

This thesis mainly studies the changes of method about NURBS curve.The model is given first, and in homogeneous coordinate system to the optimal solution of the problem.This paper puts forward through the control points, right factor and the simultaneous change their approach to study of NURBS curve.The first chapter mainly introduce the computer graphics and computer aided geo-metric design background and development.The second chapter introduced the definition of NURBS curve, three kinds of ex-pression and the nature of the curve, and introduced the theory knowledge modify source curve.The third chapter introduces the scholars about NURBS curve several methods of modification.In the fourth chapter introduces the problems of the proposed model and to solve it.
