Drawing Bézier curves in Opengl C++
Curves in Computer graphics is one of the important topics to learn. Today we are going to learn about the about a special curve type - Bezier Curve . First we know about the curves, then what is bezier curves then we will learn drawing bezier curves in opengl.
Curves
Curves are set of indefinite set of points which need not to be straight. Curves are differently defines in mathematics, hence context will tell the proper definition. A curve can be in 2d (plane curves) or in 3d (space or Euclidean Space curves). A line is special type of curve which is straight. A curve is represented with some set of equation called the equation of curve.
Classification of Curves
There are mainly two types of curves -
Open Curve : The curves which have no endpoints are called open curves. Eg - Parabola, Hyperbola. Closed Curve : When the curves end points are joined, they are called closed curves. Eg - Circle, Ellipse.
The curves can be further classified into three types - implicit, explicit and par…
