A quadratic Bézier curve.
A quadratic Bézier curve is a Bézier curve with two end points and one control point.

| Vector2f | p1, | ||
| Vector2f | p2, | ||
| std::size_t | pointCount = 20 |
||
| ) |
Constructor.
| p0 | The first end point |
| p1 | The control point |
| p2 | The second end point |
| pointCount | The number of points composing the curve |
|
overridevirtual |
Get a point of the curve.
The returned point is in local coordinates, that is, the curve's transforms (position, rotation, scale) are not taken into account.
The result is undefined if index is out of the valid range.
| index | Index of the point to get, in range \( [0, n-1] \) where \( n \) is the number of points of the curve. |
Implements gf::Curve.
|
overridevirtual |
Get the total number of points of the curve.
Implements gf::Curve.
