# Quadratic Bezier Curve

### Click and drag control points to change curve.

For more information, check out the post on my blog: Bezier Curves.

Quadratic bezier curves have 3 control points and total up the values of the 3 functions below to get the final point at time t.

- A * (1-t)^2
- B * 2t(1-t)
- C * t^2

Parameters:

**t** - "Time", this value goes from 0 to 1 to generate each point on the curve

**A** - The first control point, also the starting point of the curve.

**B** - The second control point.

**C** - The third control point, also the ending point of the curve.

In other words, if you have 3 control points A,B and C, and a time t:

CurvePoint = A*(1-t)^2 + B*2t(1-t) + C*t^2.

Note that this bezier curve is 2 dimensional because A,B,C are 2 dimensional, but you could use these same equations in any dimenion!
