Library's collection Library's IT development CancelComputer graphic can not be separated with a curve. For making a curve
is needed a method which is called Bezier method. In the Bezier is needed
polygon control to make a curve. In making a curve, beside Bezier method there is
other B-Spline method or NURBS method.
In this study is compared three method there are Bezier method, B-Spline
and NURBS, which is used as a guide of parabola curve. All three method
will be compared based of speeding process to make a curve and how big memory
is going to used in each of method.
The purpose of this compare study is understanding how to make
effective curve in each of method. In this compare study is using program
language is called Delphi 2.0. For measure speeding process making curve in each
of method is used Delphi component, is called HiResTimer.
The result of compare study is proved that Bezier method is the most
effectively to making a curve than other method with using the same coordinate
polygon. For making a difficult curve is needed more accurately. That way is have
to used B-Spline or NURBS method, which have error coordinate smaller than
using Bezier method.
