Keywords: Circle and quadratic bezier.svg 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 own Damian Yerrick 2009-10-15 Circle geometry Typographic software Splines |
