Continuity of Bézier splines

{{$t('general.by')}} Move the points to make the green curve continuous! Move the points to make the blue curve continuous! (you probably ruin the continuity of the green curve) Hide the velocity and acceleration vectors and show the mirror points! When C2 lies on the grey mirror point C1', the velocity is continuous. When the yellow mirror points C0' and C3' coincide, the acceleration is continuous. Lock C2 and C3 to an A-shape! Move the other points! {{$t('general.eg',["mouse, keyboard"])}}
