Bezier curves. Bezier curves are used in computer graphics to produce curves which appear reasonably smooth at all scales (as opposed to polygonal lines, which will not scale nicely). Mathematically, they are a special case of cubic Hermite interpolation (whereas polygonal lines use linear interpolation).

Similarly, What are the important properties of Bezier curve?

Properties of Bezier Curves

They generally follow the shape of the control polygon, which consists of the segments joining the control points. They always pass through the first and last control points. They are contained in the convex hull of their defining control points.

Also, How do you make a Bezier curve in Illustrator?

How to Work with Bezier Curves in Adobe Illustrator
1. Corner Points: Connect straight line segments to straight line segments and do not need Bezier handles.
2. Smooth Points: To create line segments that join in smooth, continuous curves, click, hold and drag in the direction you’ll want the next line segment to bend.

## What is the difference between a smooth point and a corner point?

Corner points can connect straight lines, curved lines, or a combination of the two, but in all cases, the points exist so that the path can change direction. On the other hand, smooth points are designed so that a path continues as one smooth line, without any unexpected changes in direction or curvature.

## When drawing a path with the Pen tool How do you know when clicking will close a path?

Closing Paths

To close a path, use the Pen tool. First select one of the two points you want to join, then select the other point. When you are hovering over the first point, the Pen tool will have a slash next to it. When you are hovering over the second point, it will have an O next to it.
