Bezier Curves - Modeling and Rendering
Bezier curves are utilized in computer graphics to turn out curves which display reasonably smooth at all scales. Such spline approximation method was developed through French engineer Pierre Bezier for automobile body implementation. Bezier spline was designed in that a manner which they are very helpful and convenient for curve and surface implementing and are easy to design Curves are trajectories of moving points. We will identify them as functions allocating a location of that moving point as in 2-D or 3-D, to a parameter t, that is parametric curves.
Curves are helpful in geometric modeling and they must have a shape that has a clear and intuitive relation to the way of the sequence of control points. One part of curves satisfying this need is Bezier curve.The Bezier curve requires merely two end points and the other points which control the endpoint tangent vector. Bezier curve is defined via a sequence of N + 1 control points, P0, P1,. . . , Pn. We explained the Bezier curve by using the algorithm that is invented via DeCasteljeau, based upon recursive splitting of the intervals combining the consecutive control points. For Bezier splines a purely geometric construction does not rely upon any polynomial formulation and such is extremely simple to know. The DeCasteljeau technique is an algorithm that performs repeated bi-linear interpolation to calculate splines of any order.
