Join Joe Marini for an in-depth discussion in this video Bezier and quadratic curves, part of Learning HTML Canvas.
- [Instructor] You can actually get fairly…advanced with some of the drawing operations…that are possible with the Canvas.…In fact, the Canvas lets you draw…Bezier and quadratic curves, which,…if you've ever used a drawing program like Adobe…Illustrator, you've probably seen these before.…Bezier curves are defined by four points.…They have a starting and ending point,…along with two control points to determine how the…curve is drawn from the start to the end.…Quadratic curves are similar.…They also have start and end points,…but they have only one control point.…
Each of these curve types…have corresponding functions for drawing them,…and I've listed those functions here.…So like other paths, you first use the moveTo function,…which we saw when we learned how to draw…lines in a previous example.…And in the Bezier curve case, you supply two control points…that will shape the curve of the line,…ending at the specified point.…And quadratic curves are similar, but again,…they have only one control point.…So let's take a look at this in a live example.…
