i want to draw an arc on ellipse. i dont know how to draw arc using curve, drawing arc with direct arc method wont help, since they are for drawing arc on circles(objective c)
on further searching i came to know elliptical arc can be drawn using control points. how i can find the control points for an arc.
i know the center point of ellipse(not two foci), start angle, end angle, the two points where the angles meet on the ellipse. from these how i can find the two control points.
or what else is missing to solve this
thanks in advance
