'Spline surfaces' presentation slideshows

Introduction

Introduction. Bezier curves , B-spline curves and subdivision curves are all based upon the input of a control polygon and the specification of an algorithmic method that contructs a curve from this sequence of points. Fundamental to these methods is the concept of a refinement .
