The book's unified treatment of all significant methods of curve and surface design is heavily focused on the movement from theory to application. In these days of age, very few models where available to the computer graphics community and creating them was also far from easy. Bézier Curves • Hermite cubic curves are difficult to model – need to specify point and gradient. This paper is concerned with the problem of fitting curves and surfaces, for computer aided design (CAD), via an ordered set of control points, so that the result is satisfactory for the user's needs. Curves and Surface The world around us is full of objects of remarkable shapes. Nevertheless, in computer graphics, we continue to populate our virtual worlds with flat objects. We have a good reason for such persistence. Graphics systems can render flat three-dimensional polygons at high rates, including doing hidden-surface removal, shading, and texture mapping.. 2 Computer graphics is important in many areas including engineering design, architecture, education, and computer art and animation.
