English: Quadratic
Bézier spline approximation (in red) overlayed on a black circle of radius 112 units, with tangent (on-curve) control points drawn as squares and off-curve control points drawn as circles. The spline's on-curve control points are placed at the circle's horizontal and vertical tangent points and at displacements (79, 79) from the center and its reflections about the X and Y axes. Off-curve control points are placed at the intersections between the horizontal and vertical tangent line and 45-degree lines from the diagonal control points.
